• Question of trunking GS716T and GS724T

  I have a build based on HP ProCurve switches. #2 has set the VLAN as #1 two of them have own internet streams and are #1 East to shared resources with #2 where one of these internet stream will fail or switches fails it is even WAN communication from any of these VLANS.

  Is it possible to do this with 2 of the GS724T or GS716?

  Thank you

• Stacking and trunking

  Hello

  I have a question regarding trunking in combination with the stacked switches. In my example, I have two switches that are stacked and stacked switch. I placed all the sales employees in VLAN 10 (put first in the stack) and the management VLAN 20 (second switch in the stack) on switches employees stacked. The servers are on 30 VLAN on the switch stacked.

  I need to assign trunkports between two switches stacked in order to allow the stacked switches communicate?

  Thanks in advance!

  The ports that are used for the stacking shouldn't be junction ports.  They are only dedicated for stacking, and once the two (or more) switches are stacked together, they become a single logical switch.  Think about your carpet as a simple switch.  You only need ports of connectors for the connection between the battery and the only stacked switch.

  I hope this helps.

• Ethernet VMware with Cisco EtherChannel and Trunking Question

  Hello

  Trying to get our etherchannels works correctly with our network administrator. Here is our config with a few questions.

  1. as it is to create the trunk between switch and host directly, can I use spanning tree portfast chest edge ?

  2. when don't we use no ip address and when not for this configuration? I see online showing examples with and without it.

  3. in some articles, he described in access mode , while in others he said dot1q trunk mode. See here for the access mode. Admin think it should use dot1q.

  4 Etherchannel is fully support and preferred extending from links on maps, right? Not all of the links on the same card?

  5 is this the case in order to change the load balancing algorithm in vmware first or first to the work of cisco? I did first vmware. (IP-hash)

  It's on a series with 4 cards/blades 6500 switch.

  Wow Josh. If only you had written documentation. That's the trouble with him. People like me get final instructions, because we're not the guys from network 24 x 7. Great documentation would be layout, the reasons to go this way or that way you did just. That being said, here's my summary based on this discussion.

  1. we have several VLANS that descends from 3 links on the etherchannel. Thus, we should use mode trunk because there is not a single.

  2. we have an another etherchannel with just 1 vlan (vmotion), but in all of two links. This should be the access mode. Or is it still trunk because it's the multiple links?

  3. I don't know what crash dump logger is, or how it applies to my situation.

  4. I saw the bpduguard setting before what exactly is the syntax to use for us? 6500 series.

  5. I don't know if our switch would deliver on that port. How can I tell? At this moment I have switchport setting in there.

  Thank you!

  No problem for reference, the other question of documentation is one of the languages. Their word etherchannel on HP networking hardware, 'trunk' and has nothing to do with the discussion of port "access vs circuit", which they call "tag unidentified vs.

  1 Yes

  2. you would certainly make an access port.

  3. If your server never begins to have a problem with break, VMware can a copy of the accident for the debug log. You can see an article on setting up here: put in place the collector of Dump ESXi 5.0 | VMware vSphere Blog - VMware Blogs.

  4 I'm sorry I'm not familiar with this model

  5. I think if the switchport parameter is here and connectivity seems to work, you can consider yourself safe

• Question on the trunks on SPA9000

  When I call to my trunks DID number

  Auto assist picks up the phone then I dial an extension or call and external number works fine

  But I do not know why, with one of my tracks when I compose the fact of him and then the extension it works

  but when I try to dial an external number he says samething like

  "ip call do not outgoing sip numbers other than toll free numbers allow.

  And hungs call...

  What I have to do is to call one of my DID and dial an external number my SIP dial plan.

  Is - this posible.

  Thank you

  It seems that this error message is not a typical message given by the SPA-9000.  If you have checked if the numbering plan defined on the line for this DID and FXS or the extension of the line are defined correctly, this should allow you to dial a number out unless this was the CASE the account was configured by the VoIP provider, not to do. Try to test the account DID regularly on a regular SIP phone as the SPA-941 and see if you have the same result.

• Sip Trunk design question

  Hello

  I have a requirement to pass an h323 to SIP environment environment. I'm looking for good practices, especially around security. I have 2 servers CUCM (8.5) in cities separated for redundancy. I have also 2 voice gateways which, at the present time, h323 to the PSTN, are each located in different cities.

  My requirements are:

  1. create a sip trunk instead of the supplier of the use of PRI.

  2 If the Wan link fails on a gateway provider, router replacing in the other location should be able to receive installation messages and if a user connects via extension mobility, should be able to answer the call.

  Is there a simplified design docos on for this? I hesitate to create a SIP trunk directly to the supplier for safety, thus thinking to end the call on the routers of voice with the CUBE. I am sure that it is managed from the factory and would appreciate comments.

  See you soon!

  Pieter

  Simple answer use ALWAYS the CUBE.  With IOS 15.1 T and more you have security against fraud free of charge that you can use to restrict which can address IP contacted the CUBE, that's all you need.

• Quick question from a newbie

  I want to implement VOIP trunk between two fixed location. Location A is as B location is the work from home. There is a virtual private network between the two, they are on different subnets. I want to access the PSTN line to site B to Site A (home) (work) using VOIP. In other words, I want to use the PSTN to work for voice calls when I'm working from home.

  Can I install the SPA3102 to work and use SPA901 home. No SIP server comes directly from trunk between the two. In other Woods can I just "dial" the SPA3012 using the SPA901 and get the PSTN tone. No other device will not involve just point to point between these two.

  Is it possible, is it easy to implement?

  Thank you very much

  I found the answer in the excellent "sandbox SPA3000 to save the document. It seems that this question was asked several times our apologies for those who discover VOIP it also well know what question to ask and what to actually look for!

• N3048 vlan trunk band guaranteed bandwidth

  Hello

  Ive got 2 batteries of n3048 which will be connected by a link of fiber shds 1 Gbps, there are several local networks virtual on each stack and some of them I want trunk on the binding fiber.

  an of vlan is for a balanced load diversely routed internet connection, there is a router on each site with 100 Mbps bandwidth, but also firewalls at each site that will be in the same vlan.

  I don't want no internet to run slow because something is hogging the bandwidth on the shds, so the question is how can I guarantee 100 Mbps of traffic for vlan 10 through the shds with us other traffic crossing of vlan?

  I have install other powerconnect switches and switches cisco with trunking VLANs between switches but I've ever done where I need to ensure a slice of bandwidth with QOS?

  I'd appreciate any help or advice to achieve this

  Thank you very much

  I used jperf on 2 laptops in VLAN 10, 1 in each switch then your laptop on the other switch into a vlan with jperf mode server and 3 computers, send traffic using jperf him around the trunk and which seems to work well. ive tried run qos traffic vlan first and then maxing the bandwidth through the traffic trunk vlan qos not and then vice versa with traffic vlan qos to a already maxxed bandwidth through the trunk and he still gave him its bandwidth of 100 Mbps in both scenarios.

• N2048 - VoIP QoS, data Ports and trunk Configurations

  Hi all

  I am new here and also new to work with the Dell Networking hardware. I just need to some insights into setting up a new network, that I put. We use 3 switches to N2048 for access to data and VoIP. Each port will have only have only a phone or a client PC in different VLANS.

  My question is what is the best configuration across all three powered to ensure that we have the optimum configuration for the quality of service for VoIP phones. Here is the configuration that I came up with this day.

  Global configuration

  VLAN, VoIP

  Voice port

  item in gi1/0/1 interface
  switchport mode access
  switchport access vlan 5
  VLAN 5 voices
  Voice vlan dot1p 5
  output

  Client port PC

  access mode swithport
  swithport access vlan 10

  Trunk Port

  Te1/0/1 interface
  switchport mode general
  VLAN allowed switchport General add 5,10,100
  switchport General pvid 100
  VLAN 5 voices
  output

  Thanks for the comments

  By default, the ports are configured to trust the priority of incoming user. So for your switch connections you can configure ports and trunk mode, there is no need to set general mode with VLANs voice, etc.

  switchport mode trunk

  switchport trunk allowed vlan add 5, 10, 100

  switchport trunk vlan 100 native

  For ease of deployment, I suggest to all the other general mode ports.

  switchport mode general

  VLAN allowed switchport General add 5,10

  pvid switchport General 10

  VLAN 5 voices

  With the general mode configuration, you can connect a client or a phone, or both at the same time, in a port. This will make things easy if later you decide to plug a phone in where a customer to reside.

• VLANning questions about blades MXL

  Hello

  I have a new M100e with a SAN PS4110xs case, a few servers blade and two switches Force10 MXL (switches and SAN on fabric)

  I put it all in place and works fine, but using the default VLAN for all

  I want to connect the switches to a Juniper EX3300 via SFP ports + and send the subnet SAN out so that I can connect remotely to the IP address of the EqualLogic for VMM integration management

  However, every time I try to put SAN ports in a VLAN separate-, before even that I look into the chutes for the Juniper - I lose all connectivity on the San.

  I created a new VLAN (VLAN120), but as soon as I set the ports inside they cannot ping each other.

  int vlan120

  Tagged te0/1 (this is the port of SAN)

  Tagged te0/12 (it is a single server)

  Tagged te0/16 (that's the other server)

  as soon as I do that I lose all connectivity to the San and server cannot ping each other via the iSCSI network.

  I tried to use 'no label' instead of 'tag' with the same effect.

  The VLAN is active (non-stop)

  I am at a loss for what is the question.

  Any help gratefully received.

  Select this option.

  I understood the question - I got 2 trunk in the Juniper VLAN120 links - as soon as I disabled the second interface everything arises in life

  Now I need to try to find a way to implement a SHIFT between the two MXL in the stack and a Juniper ex3300 - I managed to get the connectivity that I need, but with only a single link - as it is a remote site I want redundancy :-)

• Question S4048-on ACL

  Hello

  You have a few questions of ACL.

  I have 2 VM on the single ESXi host.

  VM - a eth0-> vlan 250, 10.172.250.20 dgw 10.172.250.1

  VM - b eth0-> vlan GTS 250, of 10.173.250.20/24 10.173.250.1

  I have the S4048 interface vlan 250.  and vlan added as a trunk ports that connect to the esx host.

  So many VM - a I can ping the GTS and VM - b I can ping the GTS

  I have assigned 10.172.250.1/24 to the interface and added secondary 10.173.250.1/24 as an ip address.

  If I want to block all traffic from VLAN 250 except for access to 10.32.80.7

  I can create a standard ACL

  and to add

  allow any host 10.32.80.7

  refuse any any newspaper

  !! I know that I do not need to deny downstairs, as it is implicit, but for the sake of clarity, I have added

  I would apply this to the penetration or the output of the VLAN250.

  I can limit the traffic so that 10.172.250.0/24 can initiate traffic to 10.173.250.0/24, but the response to tcp traffic initiated from 10.173.250.0/24

  If Yes, how do I write me the ACL and can I speak it IN or OUT?

  Sorry for the late reply. Without moving would be used in conjunction with a card without moving the policy used in an iSCSI environment.

• Several questions, the system crashes, corrupted notepad.exe.mui, SFC scan errors, cant play Battlefield 4 game

  Original title: I need help - corrupt notepad.exe.mui

  Hi all! This is my first time around these parts, so forgive me if I make a mistake and prepare for a long story.

  Quick information on my computer:

  Windows 7 64 bit

  AMD Radeon HD 7950

  8 GB RAM

  Intel i5 4670 k 3.40 GHz Quad Core

  Recently I bought Battlefield 4 for PC. I have loaded on my computer with ease but quickly came across a problem when I tried to play the game. My GPU drivers were apparently outdated and he gave me the choice of either a. cancellation of the launch, or (B) try to play anyway. Looking forward, I tried to launch anyway. No dice, the game freezes immediately and I can not play. At a time of the option.

  After traveling around for a bit, I discovered that my drivers were, in fact, to date and should update. So I downloaded the latest drivers, "AMD Catalyst Omega", and you click install (note that I have not manually uninstall previous drivers, so I don't know if it has really done anything). After that, he went through the whole process, do things (I suppose) as uninstall the old drivers and install the new. After it was over, I was able to boot successfully in the field of battle 4 and was able to play both the campaign and multiplayer without fault at 60 fps oh high heat. (Great game BTW, recommend to all who love FPS).

  Well, after a few hours, I decided to call it a night. After closing, I noticed that the bar at the bottom of my screen flickered from top down in very quickly. Naturally, I found it quite strange and decided to shut down my computer (thinking at the time, that I should probably do that as soon as the new drivers were installed - it was the result of not doing).

  The next day, I woke up wanting to start playing Battlefield 4. But, much to my dismay, my computer froze as he was loading the desktop. Now, it was nothing new for me, I had a lot of computer problems in the past, I can fix it this one as well. My first thought was just reboot and see if that will change anything. Unfortunately, he did nothing. He froze in the exact same task as he had before. It started to scare me a little. Previously, during an automatic update of windows, is the same thing. He has downloaded everything installed fine, very good, but when my computer restarted and tried to load to the top of my desk, my computer would freeze. Finally, I had to use system restore and restored my computer to a point before Windows automatically updated. After that, I disabled the automatic updates and him haven't touched since (Yes, my computer is has not been updated for months and months. I think that I stopped the download of updates at the time an update of Windows technically dirtied by malicious software that would crash the computers).

  I noticed the problem how similar I saw now was the question I had before with the updates of Windows. So I took to the system restore and wala, my computer was still running reliable update of the driver pre - GPUS. Now, I was still burning for some 4 battlefield. Whether I went through the same process as before, it would result in the same outcome, I did a little research. It turns out that someone had a similar problem for me. Their solution was to ensure that information on previous drivers had gone to 100%, and it said to use two programs called DriverFusion and CCleaner, well, I followed the instructions of the solution: uninstall the drivers - with DriverFusion - restart good computer - installation of new drivers - to go, but once again, no dice. A frozen at the exact same task as it did before.

  Now completely annoyed at all this, I'll be back and system restore to the point that I just had previously. Except that this time it did not work. Were no longer my system restore bringing back me to the settings of the computer that worked, it would freeze (and sometimes a blue screen), every time I tried from the desktop. Sometimes, I could get a few minutes before it would freeze, other times that I do not see my office. And it doesn't matter what time I have to put in place. Sometimes, the system restore would work, sometimes it wouldn't, but in two results, it would freeze at the office.

  Panic is now being that my computer does not seem to work at all. I can still run without danger made (thank God for that), but normal Windows is just the gel. As my panic slowly transforms into a will, I turn to google to see if someone is having my exact problem (Note: everything I do on my computer is in safe mode, and any internet research I do is on my smart phone). Finally, I came across a page saying: I need to use the command "sfc/scannow" and this should solve my problems. If I use the command, and he said that he detected problems, but has been unable to fix. He also said that he saved the information on the analysis in a journal, a journal that I could access. So I do! The entrance to the EXACT newspaper that speakes of the error is.

  "(Note that I stressed and bolded what I assumed important information, and it's the only mistake he came with).

  The only thing that I have noticed time and time again is the reference to a file called "notepad.exe.mui". Curious, I investigated more research and found that the file may be damaged and even deleted without knowing you, even by simple virus. Now, I know that I had a virus on my computer when the update of the driver. Try to add the pieces together, I thought that maybe this virus was the reason that this file has been going crazy and maybe even corrupt the file itself. Later in the article to tell me about the "sfc/scannow" command, he said that if it is available, I can get the file from another computer that is the same as mine. So, I borrowed laptop from my brother, running Windows 7 64-bit, publish the file on his computer, put it on a flash drive, plug it into my computer, move my old notepad.exe.mui on the desktop (Yes, I still have the original) and replace it with my brothers.

  Now for the part I did not yet understand. Replacing the file met with some success. After the first restart, my computer blue armored, but after the second reboot, it was in normal operation once again! Pre - GPUS normal update driver, that is. But nevertheless reliable running. Careful, I decided to run my anti-virus, Avast! and see if something happens. Of course, on a quick scan, he found a "malicious" file and I "moved it to the chest. To be doubly sure that all is well, I decide to run a scan at startup and have it automatically move all the malicious files, he finds 'trunk' or whatever he calls. I allow this to run at night and wake up to find that my computer still works reliably.

  Well, not wanting to take another chance, I run "sfc/scannow" once, just to see the error is still there. Nothing has changed. Sad it's not yet over, I again to replace the "notepad.exe.mui" in my computer this time that I deleted it, with one always on the flash drive. No blue screen on reboot, but I decide to again run the command "sfc/scannow". Once again, same error.

  At this point, I have no freaking idea what to do. My last two options are to use my disc and 'repair installation' and see if it makes something or just completely re - install Windows, which without a doubt, I don't want to do. Now, I can still play my old games very well. It's just I can't update Windows or drivers, fear, it may have a very dangerous effect.

  Anyone with any information which could be of use, please do not be afraid to say something. I come to this community as my last resort. Any information will be helpful, and I will watch this post like a bird of prey. Thank you for reading all of this. I'm sure it was quite the trip.

  They want a data center in a solution so I spec'ing on 1 3945 with UCS, CUCME, unit, etc. plus a 24 ports PoE Etherswitch)

  SM-ES3G-24-P)

  .

  For server redundancy, I put in a router 2921 with a blade of UCS and another 24 ports PoE Etherswitch.

  My question is this.  I can build and SVI on both routers to say VLAN20 running HSRP and then the trunk 2 routers together using a port on the Etherswitches just as I would do if I had a couple of normal switches?  Or if this configuration is not supported?

  My goal is to try to design a solution using only the routers without buying different external switches but the Etherswitches 2 in the router will have to shared resources and talk just like 2 external switches might.

  Thanks for any help!

  Hi Chris,

  I didn't test, but I don't see any reason why it won't work.
