• RV220W - implementation of support of VLAN

  Hello

  I'm new on the VLAN and wanted some comments about how I have the router configured prior to deployment.  I have 5 VLAN configured as follows:

  VLAN ID	Description	InterVLAN routing	Device management	Port 1	2 port	Port 3	Port 4
  1	By default	Activated	Activated	Not tagged	Not tagged	Not tagged	Not tagged
  2	Office	People with disabilities	Activated	The tag	The tag	The tag	The tag
  3	USDA	People with disabilities	Activated	The tag	The tag	The tag	The tag
  4	Cameras	People with disabilities	Activated	The tag	The tag	The tag	The tag
  5	Guests	People with disabilities	Activated	The tag	The tag	The tag	The tag

  The USDA and the cameras VLAN will be on the same track with a switch (I counted on MAC filtering help to differentiate) and the VIRTUAL office LAN will go to another switch (reservations MAC/IP using here), that the VLAN invited would be used for comments only, Wifi with this completely separate from other networks.

  Is there a better way to configure or what I need to do further adjustments?

  Any help is greatly appreciated!

  Hi Dwight,.

  I don't see why you would need this other router you always 4 Port you might use (based on what you wrote above) for the VLAN of the USDA.  If the device on the USDA must be reached outside a demilitarized zone would probably be the best bet.  Otherwise, this seems fine assuming that these two ports offices are connected only to the RV-Yes, it's a good idea to exclude any VLAN interfaces, on what you don't want them.

• Authentication of the junction ports?

  Hi all

  Maybe a stupid question, but I am unable to find a satisfactory answer.

  We have a couple of 3560 switches, all connected to 3750 battery. One of these 3560 switches is in an open area and asked me if that could be considered a security risk. Of course, whether in an open place is a risk, but if anyone where them unplug the connection of the trunk to our battery and then plug it into another switch, what will happen?

  Should / could authenticate us ports/channel-groups of circuits? I have all the switches configured for authentication ssh connection and network (mac based) against a radius server, but I have not configured authentication on trunk ports that I found descriptions that dot1x cannot be enabled on the ports of junction.

  Thanks in advance

  Hello

  I suggest the following:

  > Organise a physical envelope (locked) or any other control of physical security to ensure authorized access to the device. Work around any technical solution or bandage should be only temporary. What is a righteous person happening to your switches? DOS attack! This could also be done by mistake, with the result a unstructred threat.

  > Allow follow-up of these switches (ICMP, SNMP), so that you are alerted when they are disconnected.

  > Change the default NATIVE VLAN (vlan1)

  > Disable trunk negotiation (mode ON)

• Airport Extreme Multiple Port forwarding

  Y at - it anyway to implement multiple ports to one only volume, for example, that I need to set up port 55000 to 55999 and 56000 to 56999. Is there a way to put it, so I did not open them one by one?

  Yes, just use a comma or a hyphen, as follows:

  • For several ports in series, like: 5000 to 6000, use 5000-6000
  • For several ports in a series, such as 8080, 7000 and 9000, use: 7000, 8080, 9000

  For example,.

  Private TCP Port (s): 5000-6000, 7000, 8080, 9000

• Automatic detection of settings serial port using LabWindows

  Hi all

  I have a program that interacts with the device via RS232. For now, I've just implemented the port number in my code and it must be changed every time we turn on the computer. Is - it feasible that I could detect the port number first and then communicate with this device.

  Thank you very much!!

• Automatic EA6500 for PokerStars port forwarding

  When I play poker online I am sometimes disconnected. The network status report showed that it is because of my router. They recommended that do the following:

  Please set the trigger (automatic port forwarding) for the following ports: 26002 and 443 22.

  The access router configuration page and follow the instructions as a guideline.

  Click the Advanced tab.

  Click the app button

  Click the enable button

  Name of PokerStars

  After the outbreak of Port, enter 26002

  After the trigger Type, select TCP

  After the Public Port, enter 26002

  After Public Type, choose TCP

  Click on apply

  Repeat to ports 443 and 22

  In the Linksys Smart Wi - Fi, under Security, I went to the apps and games to find the port forwarding and triggering, but I don't see how I can implement a port as an example here with a public port. Can someone explain? I have little knowledge about this kind of thing. Thank you!

  First, you must go in the DHCP server setting and to reserve an IP address for the main device that you use to do this.

  Then in simple port forwarding using that IP address and the same port number for internal and external. External port, that's what they call public port.

• Advanced Port forwarding rules

  I bought a WRT1900AC router and changed my old router Dlink DIR - 905L.

  There is a function in Dlink to set a unique public port in the router to redirect a private IP LAN and LAN if necessary internal address port. This is called: "Advanced por rules of transfer".

  In this function I defined a rule like this (real case):

  Name: CCTV

  IP address: 192.168.0.120

  Public Port: 80--> 80

  Private port: 80--> 80

  Tye of traffic: all

  Question: Where can I find this function in the WRT1900AC?

  Appreciate your help, my CCTV is not managed.

  Hi HappyLefty. That's how we have implemented simple Port Forwarding on Linksys routers. Will we know what you want to accomplish with the WRT1900AC? We would like to have a better understanding of your challenge with our camera so we can help you accordingly.

• port management and control for nm-cids

  Any body can help me to find the difference between the ip address we use to ID-sensore 1/0 interface and ip address of the sensor and its default gateway

  10.10.10.2/24,10.10.10.1

  JOINT-2 information.

  There are 8 interfaces of interest when it comes to the JOINT-2.

  4 If the interfaces belong to the JOINT-2 itself.

  4 other interfaces are the switch ports connected to these 4 JOINT-2 interfaces.

  The management of the JOINT-2 interface is ' GigabitEthernet0/2 '.

  When you assign an IP to the JOINT-2 is the interface where the IP address is assigned.

  On the backplane of the switch it will connect to a corresponding switch port.

  In the BONE of cat is "/ 2", and in the IOS is the "management-port intrusion detection module.

  These switch ports must be assigned to what ever vlan door network address assigned to the interface JOINT-2 s Gig0/2.

  The ' GigabitEthernet0/7 and GigabitEthernet0/8' JOINT-2 are the JOINT-2 control interfaces and must be assigned to the AnalysisEngine for surveillance.

  On the backplane of the switch they will connect to 2 corresponding switch ports.

  In the BONE of cat, they are "/ 7" and "/ 8", in IOS, they are "detection module of intrusion-modem 1" and "data-port 2". ""

  You will need to set these ports as capture ports if follow on promiscuity, OR vlan unique ports (access-ports) if making pair interface online monitoring or ports of junction If inline vlan pair followed to do.

  "GigabitEthernet0/1" of the JOINT-2 is not configurable on JOINT-2 and is used only for sending TCP resets in promiscuous mode.

  On the backplane of the switch it will connect to a corresponding switch port.

  In the BONE of cat is "/ 1 ' and should be left a trunk port routing all the VLANS. In IOS this port is not considered in the configuration that the user never needs to change the configuration of this port.

  There are also 3 to 6 ports that are visible in the BONE of cat. But none of these 4 ports are connected to anything on the JOINT-2 module itself and can be ignored safely. These ports are not at all in IOS.

• Configuration of a port as 'server port' in UCS FI 6120

  Hi all

  It is a fundamental question. If any user of UCS can kidly help me by providing a checklist for setting up a server in the UCS port, I will be grateful.

  What I've been running a port as the port of the server using the UCS Manager and nothing more. Then I connected the ANC of 10G from the server to this UCS FI. FCoE login never happened. My setup is slightly different from that of a regular system of UCS as I am trying to connect a stand-alone server to the UCS IF instead of use the chassis. Please visit https://supportforums.cisco.com/thread/2117756?tstart=0 to learn more about this topic.

  Looks like these server ports are the ports of junction and can carry any traffic VLAN? So why not FCoE VLAN? Why no "announcement of the discovery? I hung a finisar and don't see something specific protocol FCoE from port of the server.

  Any help is appreciated.

  Thank you

  Niranjan,

  It might help to take the steps that need to occur when you connect a 10G ANC to Nexus one N5K.

  In order to get a CF on a N5K virtual connection, the following steps of the manuals must be made:

  (1) create a vfc and bind it to the physical interface where the ANC is attached

  (2) create a vlan and vsan and associate the vlan for the vsan fcoe

  (3) place the vfc in the vsan created in step 2 above

  Once these steps are completed, and a couple of closing/No.-stops, you will get a vfc on the N5K flogi.

  When you create a Service in UCSM profile and associate with a blade with an ANC, UCSM performs all these tasks for you. If you dig into the system, you will see the vfc and veth that were created for your SPs.

  Without a SP and UCSM to manage the port of the server, any of these steps occur, and you will not get a flogi. There is no method to manipulate UCSM to perform what you're trying to do. It is not in the current design of the product.

  The only supported method to attach a rack CSeries server to a cluster UCSM is using the integration of the C-series features and the necessary equipment (FEX)

  I hope this helps.

• SRW2048 - trunk port

  Hello

  I have a question according to the behavior of the trunk port.

  I need to connect Linksys Cisco Catalyst switch. On the catalyst I've implemented the port in trunk mode.

  I also put the SRW2048 port in trunk mode. But the switches are not able to communicate with each other.

  Is it possible to implement on the SRW2048 to accept all VLAN Tags on the trunk port. Because it looks like

  be slightly different behavior of cisco switches where are all the VLAN to the trunk mode port.

  I don't speak dot1q encapsulation (tag VLAN)

  The switch has the new firmware: v1.2.2d

  Thank you for your response.

  Juraj

  In contrast to the catalyst, the SRW does not automatically add all the VLANS on the switch to a trunk port. Instead, you must do all your Member VLAN trunk mode port.

• Network management using a trunk for the connectivity port

  Hi all

  I'm currently developing a couple of hosts with a unique vswitch esx. Ideally, I would like to allocate 4 physical NICS on the host to connect to my physical network via 802. 1 q trunks. These network interface cards will then be used by some groups of ports for example vlan 10,20 and 30. I also want the Group of ports management network the vswitch using one of/all of these ports of junction for its uplink to the physical network. However, I seem to lose connectivity to the host whenever I put the port network management group vmnic to one vmnic that is attached to an uplink of trunk. If I allocate an uplink access and secure it to the management network port group I do not seem to have everything get to the problem of the host.

  I have to do something wrong as having to use a physical network adapter, mapped to a vlan access, just for hospitality management seems a bit exaggerated.

  Any advice would be greatly appreciated.

  See you soon,.

  CiscoKid

  Hello Ciscokid,

  is not a problem to achieve what you want. What VLAN id you use for the management network? You specify this number VLAN on the portgroup of management?

  Do you have any "vlan native" on the physical switch port?

• Catch 22 - Port Trunk Configurations: how to combine identifiers VLAN native with DHCP (but allows traffic of VM)

  Catch 22 - Port Network Configurations: how to combine identifiers VLAN native with DHCP (but allow the virtual computer)

  I came across a Catch 22.  Maybe someone can restore the directly here.  I found a "witch hunt" for sure.

  It comes with the Ports of junction on the side of the switch of the ESX host network.

  Context:

  Ok. The Setup is a HP Blade C7000 enclosure.  I try to configure ports for switching to the blades.  ESX 3.5 U4 will be installed the BL460cs.  Installation is preferred method: revive unattended.  No problem with the syntax of Kick-Start,

  I am here, it's the side network.

  The problem:

  I find a major complication in that the switch ports must be configured for both traffic Service Console and VMkernel, more Virtual Machine since only two NICs by blade. Not best practices, but we have only two switches Cisco 3020 inside.  The two uplink physical NIC is paired in the same vSwitch.  (No iSCSI does fortunately).

  So the Catch 22 question is as follows:

  If the id VLAN native set up on the switch port, DHCP works of course and the VMware boot loader is able to grasp a binary / packets on the network (FTP Site) and install OK.  But after no installation, no communication with SC unless I set the VLAN id of the SC to '0 '.  The value "4" 0 does not communication, but "40" is the VLAN native.

  If id configuring VLAN native retired from the Switch port, DHCP will not work and host does not have IP address during the VMware boot process.  This is as expected as traffic without label is not assigned an eligible

  VLAN, so no comms.

  The Port of the Switch configuration:

  interface GigabitEthernet0/16

  SERVERNAME description

  switchport trunk encapsulation dot1q

  switchport trunk vlan native 40

  switchport trunk allowed vlan 40-254

  switchport mode trunk

  switchport nonegotiate

  Speed 1000

  No cdp enable

  spanning tree portfast trunk

  end

  Summary

  OK, let's summarize where things are and if possible please attach responses to their digital identity.

  (1) is there a way to delete the VLAN tagging altogether side ESX host? Not only the id '0 '. The problem is with clearly with the VLAN native defined as "40".  If "40" IDs specified on the Group of ports for the Service Console, no joy, no comms. If the id of '0' value, capable of ping gateway and communicate on the network.

  (2) what is the problem with the definition of VLAN native as "40" when the config for the switch port is set as VLAN native "40"?  Or if it was a problem?  Both parameters clearly do not work together.

  (3) a switch receiving a unmarked frame it will assign to the VLAN Trunk native. Ok. Trunking bases and why I need a VLAN specified on the port for DHCP native work.  But it seems that since the id VLAN is set manually even as VLAN native, closed communications and no traffic as possible.

  (4) executives made tag 802. 1 q VLAN native?  I think that it is not and this could well be the problem. Since the id VLAN "40" is not labeled, but try to score the side host vSwitch port group.

  Please let me know your thoughts, community and how in general, we are approaching 2 NIC ESX configurations.

  When trunking multiple VLANs, you either have a default VLAN is nothing is tagged, or you don't.  That's what the vlan native to you, it defines which VLAN would be used if no tag is visible on the packets traversing the network.  For servers, if you are marking, then everything has to tag, if you're not marking at the server level, then the port must be either an access port or a VLAN native or default must be set.  I also don't keep your service console the same network as your vm.  Keep this isolated for the security of the network.  If you isolate this VLAN, you can separate and use a single IP address for installation and one for post construction.

  Or, you can provide an IP address during the build.

• Deliver the addition of new set of switches stacked as an extension to the network in another data center building

  Hello

  I was wondering if someone can help me, I am a humble sysadmin with no real network admin training.

  I have the following Setup to work in a rack in our data center.

  2 x Dell Sonicwall NSA2400
  2 x stacked switches Dell Powerconnect N5524

  A Sonicwall is connected to each switch (active-passive)

  Every Dell server has 2 x nics in servile failover mode, one of each network card connected to each switch

  This is done to allow a full redundancy for network, cable, switches and Firewall interface cards. It works well.

  The above mentioned rack is now full and we ordered a new rack that is in a different datacenter of construction on the same site. We decided to buy another set of stacked switches and _extend_ (no battery) these via optical SPF on the rack on the other.

  The idea is that we still have the switch fault tolerance but link to two grids through 10 GB. The new switches are 2 x Dell Powerconnect N2048 and have been implemented stacked with any connected devices.

  I have implemented SPF ports on both switches to be a junction ports and connected the two sets of switches, unfortunately our site went offline, our alert went ballistic and no servers could not talk to each other!

  Quickly, I unplugged the new switches and after a worrisome 10 alerts deleted seconds and the site is back online.

  I don't know why this has happened and reflected on the STP parameters that my googleing seem well. I don't know I'm missing something basic.

  I'll post a framework and a diagram in a follow-up post

  Which is no doubt tree covering the shot weight. It is a good idea to assign lower priority to the main switch. Generally, your root switch will be the one that plugs into the firewall. Definition of priority on the main switch to 4096, it will make the root switch. So as you work your way through different layers of the network, increase the priority. Access layer switches can be left by default.

  I would also check the physical connections for loops. In situations where you have multiple connections switch, make sure that these ports are configured in a SHIFT.

  Keep us informed.
