• How to block all communication port

  Hello

  I've got sg - 300 cisco cisco switch. I want to make connections between 2nd port on the 3rd and the block between 3rd and 4th port communication.

  In short, 2nd port must Access all ports located in the same switch, 3rd port not to communicate all ports except port 2.

  and 4th port should not communicate all the ports except port 2nd...

  How to do this? is this possible... Please help...

  Hi sundar, this can be done with protected Harbour located by editing a port under the administration of the track. This will isolate all individual ports to see each other while using the uplink port. If you need one of these ports AP to connect then it will need to access lists.

• Home network and multiple switches

  Hi, I put to level my small business network that ran from ports on my Cisco SG100-24 switch. I bought another SG100-24 who will give me the required ports. My question is how best to connect them.

  I am currently using modem from my ISP to a router Cisco RV320 24 / first SG100. I see two options a obvious here being just string them or simply each connect to the router as more of an approach to the tree. I also have a 8 switch (SG200-08) port, but not sure that I need more with the new switch 24 ports so it's a "Smart Switch".  I guess I am curious to know if there is any advantage to use mini-GBIC combo ports (with or without having to buy the modules) or simply to browse the two switches of the RV320.  I also use a WAP 4410 so my current pan is as follows:

  1. Port RV320 1-> SG100-24 #1
  2. Port RV320 2-> SG100-24 #2
  3. Port 3 of RV320-> WAP4410N
  4. RV320 4-> server port

  I'd appreciate thoughts and suggestions, in particular with regard to the combo Mini GBIC ports.

  Hi Jason,

  There are a few ways to accomplish the same thing.

  1. you can, as Mike has suggested to continue the physical isolation and each of the SG100 place switches VLAN different interconnected via a RV320 router.

  2. If you need more ports for one of VLAN perhaps physical isolation is not possible, then you may need to add SG200-08. You can try to disable some settings that can improve performance, such as Hello, Smartports macro, even STP and Green Ethernet.

  I hope this helps a little.

• Virtual MACHINE is unable to ping host and vice versa

  It is a very strange problem.  VMWare support tried to understand this output as Dell.  So, I just throw it to the community to see if anyone else has experienced this problem and may have a solution.  I have 3 identical Dell R720 servers.  2 work with no problem, but 1 (let's call it vm8) gave me problems since day 1.  Reference verified Dell equipment today and has updated me the BIOS, firmware and drivers on vm8, which did not solve the problem.  VMWare technicians checked each parameter network in recent weeks and currently, they are not the cause.

  VM8 have ESXi installed 5.5.0.  The Server 4 has 2 NICs with 4 ports each.  Current configuration is vmnic 0-3 is connected to our LAN, 4-5 on our DMZ and 6-7 in our SAN (iSCSI). The AP will go up and down because VM8 loses connectivity to our isolation address (gateway).

  VM8 (Mgmt IP network is 172.20.100.9) has only 1 VM (172.20.100.40). Same subnet (255.255.255.0).  .9 happens to ping expiration.40 using vmkping.  When I ping.9 de.40, the first package gets a quick response, then all following packets timeout.  According to VMWare, when you ping in (VM to host) it does not go out through the card physical network to the physical switch.  Everything is internal with vmnic and vSwitch.  When I ping my gateway (172.20.100.1), the ping is successful.  When I ping.9 from my workstation, the first packet times out, then answered the following packages.  It is the exact opposite of ping the virtual computer.

  Here's a better ventilation-

  .9 VM8 host

  .40 VM on the host VM8

  .1 gateway

  .122 workstation over LAN

  .25 vRanger connection (physical server on LAN)

  Ping

  .9 40 (100% packet loss)

  first package de.40 a.9 (75% packet loss) Gets the response, then 3 timeout

  .9 a.122 good ping (0 packet loss)

  .122 a.9 (0 packet loss) good ping

  vmkping (75% loss).9 a.25 does not appear each packet that it is sent.  But other results, can I assume first package times out.

  first package de.25 a.9 (75% loss) has expired, the following 3 got a response

  .40 a.122 good ping (0 packet loss)

  . 122. 40 (100% packet loss)

  The 3 can ping a.1 (every 20 minutes on VM8 I get a "vSphere HA agent on this host failed isolation address 172.20.100.1"

  Also, throughout the day, I get the message - "vSphere HA agent on this host cannot reach some of the management of the addresses of network of other hosts, and HA is perhaps not able to restart the virtual computer if a failure of the host is displayed."  I came to work in the morning, and all my VMS on VM8 migrated to my other 2 hosts.  My backups don't work on VM on VM8.  I use vRanger connection and when I ping connection vRanger VM8 (physical server), the first package expires and the following packages get a response.  Then, when connection vRanger goes to back up my VM, runs aground due to loss of original packet.

  These are things I've already tried.  I tested individually each physical NETWORK adapter.  I removed all the ports on the two NIC to try to isolate a specific port. All the 4 vmnic is active adapters in network properties NIC Teaming management and I moved each vmnic individually to unused to test each port.  I replaced the Cat6 cables.  I used different Dell switches and various ports of the switch.  I even swapped the switch ports that host another employee, exclude a switch port configuration problem. In addition, port security is disabled on the ports.  I upgraded ESXi 5.5.0 to a newer version.  There is a known issue with the tg3 driver, which I've updated to the latest version without problem.  I also used tg3 workaround by disabling NetQueue.  And we do not use of VLAN. Dell technical support says that it is not a hardware problem and thinks it's a matter of layer 2, but does not know where.  Basically, it's an internal problem (meaning strictly on VM8) with vSwitches or vmnic or it's a material gremlin in our Dell R720 box.

  The final recommendation of Dell is to blow the ESXi server and install a clean copy.  It's extremely frustrating and I'm out of ideas.

  Thanks in advance.

  Any luck that you have an IP address that is duplicated on your network?

• Page setting for the Port SG200-26 1.4.0.88 corrupt firmware / Firmware Bug?

  Hello

  After the upgrade to 2 switches SG200-26 version 1.4.0.88 firmware, I am unable to set up the CONFIGURATION of the PORT page.

  See the attached images.

  Must be a bug in the firmware.

  Please notify for the solution!

  Hello Dimitris,

  According to the instructions mentioned in the release notes, the downgrade is possible. Please you have the boot updated as well (it is a part of the firmware package)? (answer to this question does not depend on possibility of downgrade).

  What about other browsers, don't know you the same problem with Firefox or Chrome?

• Security SG200-26 and port

  We have a 26 SG200 and unfortunately one of its ports is connected a mute switch. Whenever this silent switch is disconnected and reconnected several things happen.

  1 port security intervenes and dynamically blocks port even if all ports are the default classic locking. We have not changed the default settings in the port security

  2. the Macro for "IP phone + Office" runs like dumb switch has several PC and Cisco IP phones plugged into it. This caused the PVID (2), I manually assigned to the switch (2) to changed to 1 which is the VLAN by default set in the "settings of VLAN by default.

  Is it possible to effectively disable the port security, or should I disable Smartport.  I guess that what is originally kick port security is that the switch expects that there is only 1 or 2 MAC addresses and all of a sudden it's getting 10-20? I'm not sure but I can not think of another reason that it is not like we are plugging into new devices, then it should have already learned these MAC addresses.

  Mr. Sammycbmi,

  You could disable Smartport for this interface or manually change the port to a switch port.  As a switch is connected to this interface.  However, this may affect some functionality if you have phones and PCs connected the switch turned off and the different VLANS.

  Another option is to change the port to access the mode and allow only the traffic of data VLAN or VLAN voice.  However, with this, you will need to take appropriate measures for your network based on what you want off as interface/unmanage.

  Hope this helps,

  Michael D.

• Isolate the port on a vSphere standard switch traffic

  Hello

  I deploy an environment where I have a pool of 100 virtual machines that live on a switch standard vSphere isolated. The virtual machines to communicate with the rest of the world through a virtual double-NIC machine. This configuration does not work as expected, but I would go a little further and to isolate the connectivity network, such as each virtual machine can communicate with the system of double-NIC and not each other. The switch standard vSphere, the pool of 100 virtual machines are all located on the same VLAN and group ports. I spent some research time through documentation, but I did find a clean way to implement what I want. The best I can get to each of the virtual machines 100 puts their own VIRTUAL LAN, but it is ugly and will be difficult to maintain. Is there something easier that I missed?

  Thank you

  Steve

  PVLAN, but you will need the distributed virtual switch.

• Implementation of VLAN and QoS for VOIP on SG200-18

  We recently purchased the smart switch SG200-18 to replace a Netgear switch. We are moving our phone service to VOIP through our local ISP as well.

  I currently have the VOIP phone plugged into Port 17 on SG200-18 (it is a Grandstream Cordless VOIP phone).

  I want to put the VOIP phone on one VLAN separate from the rest of the network and optimize QoS parameters so that the VOIP phone has exceptional audio quality even during network traffic.

  Here are my questions:

  1. do I need to set anything on the type of port to Port 17 (because it resembles a shape any Combo port)?

  2. How can I do to isolate VOIP telephone it's own VLAN (I see the parameters VLANS and VLAN voice, not sure that one to use;) I've tried to set a VLAN and broke the Internet connectivity on the phone until I went and removed)?

  3. do I need to adjust the QoS settings to switch to better optimize the VOIP phone?

  Some additional questions about the GS200-18 in general:

  1. do I need to adjust the parameters of the system on the switch time? I am in the Central time.

  2. do I need to adjust the Green Ethernet/Energy Saving parameters or should I stay with the default settings?

  In addition, a couple of "getting started" questions for Cisco:

  1. I registered an account My Cisco. What should I do to register my switch with Cisco and associate with my My Cisco account?

  2. What are the benefits of purchasing a contract of Cisco Small Business support, and how much would it cost the SG200-18 (I ordered it from Provantage)? I'm curious to see if it's worth the money.

  Here's my 'features ':

  Switch: SG200-18

  VOIP phone: Grandstream DP715 and 710 handsets

  Plugged in: Port 17 on SG200-18

  Services: Internet Local (Direclynx)

  Type of connection: 3 m down / 500 k up DSL move to a future wireless connection that will give us higher speeds

  Backend VOIP provider: VOIP Innovations

  Router: Apple Airport Extreme AC model (all Macs and iOS devices and the OS X Server on the network, so I use the Apple router facilitates installation, because is not QoS, trying to QoS and VLAN in the switch)

  Thank you all!

  Hello

  I'll just go to the list again:

  1. sounds good in the port from the drop-down list. So can I just connect the VOIP phone and go with it, correct?

  Yes, just plug in ethernet combo port and it will work.

  2. is not an issue, but I agree, Apple likely isn't compatible QoS or VLAN.

  3. thanks for the info on time/NTP settings. If I wanted to go there and try to configure NTP, how much is it and what I have to do? I want to I can give it a quick try.

  To Setup NTP on the switch is quite simple.  Go to Administration > Time Settings > time system and check the boxes to activate the main clock Source (SNTP)

  Then go to the settings of the SNTP page and add a new entry with the IP address of an NTP server.  There is a list of available NTP servers here:

  http://www.pool.ntp.org/en/

  You must also ensure that the switches Administrative default gateway is set correctly (it must be set the to the default gateway, probably the most convenient airport) so the switch can contact the NTP server.  That option is set under Administration > Interface Management > Interface IPv4.  Change the user-defined default gateway and enter the IP address of your airport (or whatever your default gateway for your network)

  4 sounds good on the Green Ethernet settings. I'll leave it as default value.

  Yes, better to just let those unless you have weird problems with ports disconnect, who can sometimes be caused by Green Ethernet, but if there's nothing like leave it on and save a few watts.

  5 sounds good on does not need to attach my passage to my Cisco account. Should I fill out a form any registration of the product with Cisco before calling support?

  It is not a record for support.  The only thing we need you to do is to create a Cisco account, but you have already done this, so if/when you call in support, you just need your ID for Cisco (also called a CCOID sometimes) and the serial number of your switch.

  6. thanks for the info on the Service contract. Is it something that I would need to order directly from Cisco or I who would get my Cisco partner (Provantage)? After the three years is up, treat yourself to renewal or it just falls? Is there a certain amount of time I have to buy the Service Contract forward make me ineligible?

  Support contracts are purchased through a partner Cisco, or you can get them online for the CDW or Newegg for example.  Basically, you have until the expiry of your current aid for the purchase of a new contract.  For example, right now your switch comes with 1 year of technical support.  You can only buy a contract while it is still active.  Once your three-year contract is about to run out, you're in the same situation.  You can renew it before it expires, however if you leave is up, you will not be able to put a contract on it.  Contracts are not my specialty, however, so you can check with your partner for complete details.

  7. sounds good to how data use VOIP calls. His dislikes too. :-)

  I agree, a voice call is not much traffic.  What you have described you probably don't have problems, although of course I can't guarantee that.

  8. because it is from your provider and they specifically mentioned the VOIP, I would say that you'll be fine here.

  You had also placed on your airport using access point behind a router in small businesses.  I would like to say that it is possible, a large number of wireless routers have an option to put access point only mode or something like that, but you should check with Apple on how to do it.

  Insofar as a Small Business router if you decide to upgrade for the options VLAN or QoS, I would recommend the RV180, or perhaps the RV320.  Two of these models are available with or without wire depending on what you decide to do with the airport.

  I think I got all the questions, but if not just let me know,

• DHCP for several local area networks VIRTUAL via SG200 - 50 p

  Here's my scenario.  One of my clients is an executive suite.  Each office gets its own internet through a separate router.  It is a big mess of wiring and confusion.  I want to simplify this by using a single router that feeds a single DHCP subnet to a confgured to switch SG200 - 50 p with multiple VIRTUAL LANs. I was able to do this by connecting an ethernet cable from the router to each group VLAN ports.  So VLAN1 has 4 ports, the first is connected to the router.  VLAN2 has 4 ports, the first is connected to the router etc.    Each VLAN is done with success of DHCP, I isolate traffic between the VLANS.  There is no cross = ping between the VLAN, which is what I want.  And each VLAN can access resources within its VIRTUAL LAN and also provides access to the internet.  Bravo HOWEVER, I would like to provide DHCP to all them VLAN on a single switch port, rather you use a router to power for each grouping of VIRTUAL LAN port.  Because my router is limited to 4 ports, I am limited to 4 VLANS.  I need 12.   I guess this is accomplished in trunking all the VLAN of the to a single port.  But I failed to achieve.  Any ideas are much appreciated.

  Hi Andy, it depends on what one of your routers support. The switch supports 802. 1 q. One of your routers must support a trunk or subinterfaces with 802. 1 q capabilities. It is very important for more than just DHCP. Since I use a single wire, all the VLAN except the vlan native will not have access to the internet unless the router can understand tags vlan.

  My advice to you is first to identify the capacity of your routers, know which router you have / want that supports 12 VLAN and 802. 1 q. The configuration should be the easy part.

• Execution of shared USB port

  Hello:

  I use a key USB Hub (x 8) RS - 232 and I created a Subvi to read the data via a port COM using VISA. Everything works fine.

  When I try to run two instances of the same Subvi in parallel (with two instances of the same VI on the block diagram with different COM ports as inputs), the SubVIs are not running at the same time, but in the order. What settings will allow to run the SubVis in parallel and share the USB port?

  Thank you!

  Dan

  Hi Dan10

  Have you tried

  "VI > properties > run > run (Checked) reentrant'?"

  You should be able to communicate with

  -different instances of the same program (VI) on different ports... is not serious USB, series, GPIB.

  It works for you?

  (However you want to access the same port, then you will need to isolate your 2 instances (such as MISTLETOE) talking to the same resource driver underneth.)

• isolate the imposing of the event

  I'm controlling a valve using my serial port that sends a signal to turh in clockwise or counterclockwise. To reduce the CPU usage I put this in a structure of the event so that the signal is sent only once as opposed to each iteration, which now works. However, this seems to have stopped everything. The only time wherever my advance program is when I operate the switch to turn the valve.

  How to isolate it the action of the structure of the event so that the switch works, but everything else works as well. For example my elapsed time is displayed once I have activate the switch, but then it won't change until I have press the power switch again. It's exactly like pressing the lap button on a timer instead of watching the progress of the time elapsed before. See attached file to see what I mean.

  I tried to put the two parties in their own while loops, but met with little success. I'm new to labview, help you to everything which can give is welcome, ideas?

  Thank you for your help in advance.

  Try this. I just put your code inside the event of timeout. You'd never put the time.

• Unable to forward Port 5900

  Hi, I think I tried everything I could think to forward port 5900 with no luck. I have e4200. This is for the purposes of RealVNC. I followed the steps from here:

  http://PortForward.com/English/routers/port_forwarding/Cisco/Linksys-E4200/RealVNC.htm

  I have windows 7 and internet safety of nortn. I've disabled the firewall and added a rule to redirect port 5900 under windows but does not help either.

  any idea what else do I do? Thank you.

  Thanks for all your replies. However, pfporterchecker has always said that the port is not open! Here's what I've tried so far:

  -reset the default router

  -windows Firewall includes the exception for port 5900

  -updated the firmware (there was a new one that just came out a couple of days!)

  -filter disabled in the Security tab options

  -forwarded port according to the link in the ther first port

  How about you, you isolate the problem. Try front/open another port number and see if that will open uisng pfporterchecker. If it will also say 'Not open', try disabling UPNP and then check again through pfportercheckern.

• LACP hash between N3048 and CISCO SG300/SG200 + question Twinax attach direct cable

  Hello

  In my network I have deployed two new N3048 with 2 transceivers SPF + and SPF module back + as core switches are connected to other 3 switches from edge of N2048 using optical fiber and I reused my previous CISCO SG300 and SG200 goes to serve the other two boxes of my campus via the spine in copper.

  I have 4 copper cable which starts from the hub of the SG300 network and 2 the SG200 brass. I set up to have a redundant connection using 2 + 2 with SG300 and 1 + 1 with SG200 RSTP.

  So for the SG300 I re LAG + LACP to have two channels of the N3048s port, but now that a single cable is connected because I don't know what kind of LACP hash mode should I put on N3048 to have a compatible hash between Dell and Cisco switches.

  My N3048 have mode 7 (Advanced hash) as default but I guess that cisco models do not understand... so, what mode is the best for LACP work perfectly with small business cisco switches?

  I also received my twinax cables to connect my two N3048 via SPF + back modules... conhot can I plug the cables into the slots SPF + (already mounted) without turning off my basic switches?

  Thank you!

  See you soon

  Cables can be connected/disconnected, but I don't know if the real module SFP + for the rear of the N3000 is hot plug.

• SG200 to VLAN SG300

  Hi all

  I have a client with of several SG300 for VLAN1 for data and voice VLAN10. PCs are piggy is interrupting the phones and showing in the fine SG300:

  

  A Department has recently employed more people, so we have a SG200 switch to connect the computers and phones. I don't seem to be able to get all the connectivity between the new switch and the SG300 it should connect. I have installation VLAN1 and 10 according to the images below:

  

  

  (Most likely) I'm missing something obvious here?

  Thanks in advance.

  If all ports are 1u, 10 t between the two switches, there is a different problem.

  I guess it's possible that the new switch SX200 can act only wobbly. Pass you any firmware prior to installation?

  I probably load the latest software and the switch to make sure it isn't being weird with you.

• on WAP 321 trunk port

  I intend to deploy cisco WAP321 on my client and after rading the document on WAP321, he said the WAP321 support for VLAN ID function, but I can't find that it supports for trunk port because I would like to connect the LAN 321 WAP port to the cisco SMB switch SG300/SG200. is the trunk port already activated on port LAN 321 WAP so I don't have to set up or not?

  need your support and help

  Hey Bram. Yes, it supports the trunk. You configure it vlan untagged on the local networking. VLANS with each switch is no problem.
