I have discovered the reason for the trouble I was having, this was not related to mtu or switch configuration. We were connected from site to site over T1, using Adtran Total Access 850 units at both locations. Apparently these units do not pass 802.1q vlan tagged packets. The person I spoke with at Adtran said this is something intrinsic to all channel-bank equipment - I don't know if he means all Adtran brand units, or all channel bank units in general. Adtran suggested a hybrid solution involving a netvanta 3200 used in conjunction with the ta850 to resolve the issue. In the mean time, we've elected to live without an appearance of the second vlan at this location.

Wow! Excellent idea! system mtu routing 1500 is set on both switches. I can from the client pc on vlan 29 on switch gc2960 send packets up to 1472 bytes when native vlan is set to vlan 29 on the trunk port. More, and we receive an error that the packet needs to be fragmented. When native vlan is NOT set to vlan 29, I can ping with packet sizes up to 1468 bytes. Anything larger than that is not returned (no error). It does not seem that "system mtu routing" is something I can set on the 2960. Can you suggest how to set the mtu?

Hi Cisco Support Community. I posted earlier about this but have not found resolution. However, I have learned some more about the problem. Here is a portion of the network. On switch gc2960, we want to have clients on vlan 29 and vlan 27. We are connected over trunk port between switch gc2960 and the stack ch3750. We used to have it connected to the switch ch3550 but it exhibited the same issue... I plan to retire the 3550 switch so that's why we're on the 3750 now. The connection is on a fractional T1, split out by Adtran 850 units at either end. Both devices are connected to the ethernet interfaces of their Adtran 850's. I don't know if this makes a difference, but the other units are connected via other means and work as expected. When native vlan 29 is NOT set, we can ping, telnet, resolve dns, etc. but we simply cannot use any web browser (firefox or ie both). It times out when browsing to anything. I use netstat -a on the client pc and I see the outbound connections on port 80. I know that data is coming back to at least the unit ch3750. This is both to targets on the internet, as well as for things on other parts of our organization's network such as a print server web management interface. When native vlan 29 is set at both ends of the trunk, we can browse the web using firefox, ie, etc as expected from client pc's on vlan 29 on the gc2960 switch. But vlan 27 clients get the issue where they cannot browse, but can ping, do dns, telnet, etc. What I am thinking is: for some reason, the "high ports" are not getting back to the clients on vlan 29 or vlan 27 unless we set the native vlan. Why on earth would this be the case? I am stymied by this. Thanks for your comments.

Glen, Originally, I had the gc2960 connected to the ch3750 unit shown on the extreme left of the diagram as trunking. I moved it to f0/5 on the 3550, thinking we had too many switch hops or spanning-tree issues. The problem persisted. But... That's *exactly* how I had it configured. It should work, but doesn't. In this configuration, clients on vlan 29 had the problem with inbound tcp stuff. Let me be more explicit about the trouble we were seeing. A client pc on vlan 29 running windows at the GC site was able to ping any web site. It could resolve DNS. We could browse to previously-resolved web sites, for example google would appear and we could even receive google's type-ahead search. But we would go to some random web site, and it would just sit there and the throbber would spin. Eventually it would time out. This was veirified on two other pc's on vlan 29. Why ICMP ping would work, but TCP web sessions would not, is a mystery I don't fully understand. We tried some of the obvious client-side solutions. This was seen in both ie and firefox. We switched to google dns server. We checked to see that proxy was off. We checked to see that appropriate routes were present on the firewall and the ch3550 switch. We put the ports ch3550 f0/5 and gc2960 g0/1 from trunk to access vlan 29 and it worked. The access vlan 29 shown in my running config above is a relic of that. I called one cisco consultant. He was stumped - suggested it was a weird firewall problem, perhaps it was out of sessions. I called the firewall manufacurer, Fortinet. Our unit is a 60b, rather old. They turned on packet tracing. We could see the outbound packets from our test client on vlan 29. We would also see return packets - I even saw text of a website that I recognized in one packet. So traffic is getting at least back through the firewall, and it's not an issue of the firewall being out of sessions. Regardless, I ordered a new firewall. it is sitting on my desk, I haven't tried it yet. We needed a new one anyway. I used a different port on the ch3550. It used to be on g0/9 I think. I replaced the gc2960 switch with an old crappy dell powerconnect 3024. I set it so some ports were untagged on vlan 29 and some on vlan 27, and set tagging on the 3024's gigabit port for both vlans. I set the upling port as native vlan 29. This configuration had worked elsewhere in our network. I changed the ch3550 f0/5 to trunking. Same result as before. This tells me the problem is not with gc2960. I called another cisco consultant. They were equally stumped. These are the guys who suggested adding native vlan 29 to the trunk port. With this, client pc's on vlan 29 could finally browse as expected. We just bought a used ws-c3750g-24t off ebay to stack with the existing ws-c3750g-12s labeled as ch3750 so as to eliminate unit ch3550, thinking maybe there is something wrong with ch3550 or we are having spanning-tree issues or something. We haven't received it yet. We were also planning to do that anyway to simplify the network. thanks! Message was edited by: Network Support to correct typos

duh. just noriced switchport access vlan 29. maybe taking that out will help for vlan 27 traffic. Will advise, but need to drive out to the site to check. But... why do we need to do native vlan 29 anyway? I would think it would work without it.

yes, the firewall uses all static routes, that point to ch3550. Also, the switch ch3550 has a route to vlan29. this is the config as of just now. gc2960#show running-config interface gi0/1 Building configuration... Current configuration : 92 bytes ! interface GigabitEthernet0/1 switchport trunk native vlan 29 switchport mode trunk end ch3550#show running-config interface fa0/5 Building configuration... Current configuration : 183 bytes ! interface FastEthernet0/5 description trunk to gc2960 switchport access vlan 29 switchport trunk encapsulation dot1q switchport trunk native vlan 29 switchport mode trunk end

Cisco Support Community, I hope I am articulating this problem correctly: We have a switch gc2960. It has ports configured on vlan 27 and vlan 29. It is connected to switch ch3550. It has presence of vlan 27 vlan 29 and also vlan 18 and several other vlans. Our internet firewall is connected to ch3550. It is a fortinet product, so this is not indicated on the diagram. When the two switches were connected on vlan 29 access ports, pc's on vlan 29 on gc2960 worked as expected. vlan 27 clients of course did not work. When we switched the connecting ports to trunk ports, some weird stuff happened. Clients on gc2960 on vlan 29 could ping and resolve dns, but not browse the intenet. The same was true for clients on gc2960 vlan 27. We verified that packets from the web were coming in through the firewall. What we were thinking, is that they somehow were not being tagged to vlan 29 even though we were trunking. When we set native vlan 29 on the trunk, then clients on gc2960 vlan 29 operated as expected. However, clients on gc2960 vlan 27 are still having this problem, we can ping and resolve dns but not browse. Consider the other switch ch2960-jstreet which has presence of vlan 18 and vlan 27. It is also connected on trunk to ch3550. We are not using native vlan on this trunk, and traffic works as expected. Is the lack of presence of vlan 18 a factor as to why gc2960 is not receiving the tagged packets correctly? Should the interface vlan18 on gc2960 have an ip address on the vlan 18 network? Thank you all for your comments and advice.

Hi Cisco Community, On my 2960, 3550, and 2801 equipment which all have IOS 12.2 or 12.3 I am able to obtain things like "show tech" and save it on a tftp server in this manner: ch3550#show tech | redirect t ftp://192.168.18.18/techsupport.txt This is because the | pipe has a bunch of options it refers to as output modifiers. ch3550#show tech | ? append Append redirected output to URL (URLs supporting append operation only) begin Begin with the line that matches count Count number of lines which match regexp exclude Exclude lines that match format Format the output using the specified spec file include Include lines that match redirect Redirect output to URL section Filter a section of output tee Copy output to URL HOWEVER, on my 3750, I am not able to do this. The list of output modifiers has changed, and "redirect" is not available. Consider the following: ch3750#show tech | redirect t ftp://192.168.18.18/techsupport2.txt ^ % Invalid input detected at '^' marker. ch3750#show tech | ? begin Begin with the line that matches exclude Exclude lines that match include Include lines that match The 3750 unit I am working with is WS-C3750G-12S with IOS version 12.2(25)SEB2 Now, I know I can capture the show tech output via other means such as in the buffer of Putty.exe... but finding this out has become a matter of principle now! thanks! mtoal

Hi CSC, This is more of a philosophical or "best practices" question. I have a Cisco 3550 at the home office. Connected to the 3550 is a number of branch offices by way of T1 circuits or VDSL modems. They all come to the home office, where we have a central internet connection and server farm for our entire organization. Except for one special case branch office, we don't forsee the need for appearances of the home office vlan at the branch office sites. In that case, we bring it into a trunk port at the home office, and at the special case branch office we have a dell 3024 switch and tag some ports as vlan 18 (the home office) or vlan 27 (the special case branch office). We also do not forsee a need for the vlan from one branch office to appear at another branch office. They are all (except for the special case mentioned above) currently configured something like this: interface FastEthernet0/1 description home office switchport access vlan 18 switchport mode access ! interface FastEthernet0/2 description t1 to branch office 1 switchport access vlan 19 switchport mode access ! interface Vlan18 description subnet for home office ip address 192.168.18.1 255.255.255.0 ! interface Vlan19 description subnet for branch office 1 ip address 192.168.19.1 255.255.255.0 Is it better, in terms of reduced network complexity or performance on my 3550, to do something like this instead? That is, to make the interfaces router ports as opposed to vlan member ports? Of course, if we ever DID need to have appearances of the home office vlan at branch office sites, or appearances of one branch office's vlan at another branch office, we would lose that flexibility. interface FastEthernet0/1 description home office switchport access vlan 18 switchport mode access ! interface FastEthernet0/2 description t1 to branch office 1 ip address 192.168.19.1 255.255.255.0 ! interface Vlan18 description subnet for home office ip address 192.168.18.1 255.255.255.0 ! no vlan 19

Just to be sure, I made another t1 crossover cable. Looks like my original t1 crossover cable was bad! With the new t1 cable, serial 0/3/0 comes up on both units. I am able to ping each unit from the other unit. Test your homemade cables!!! And, I do appreciate the tip about line versus internal clocking, this was also an important key to resolving this issue. Thanks a lot, vmiller!!!!

Hi there, I wish to create an ethernet bridge between different network segments on the same subnet over t1. I am replacing two adtran ta850's with two cisco 2801, each router has wic-1dsu-t1-v2 installed, to communicate over a telco t1 from Qwest. We need to do this because of an application that uses multicast udp is communicating over the network and requires 100mbps full duplex... the adtrans are gen 1 and only give 10/half and the application vendor thinks this is a problem. I have made a T1 crossover cable to connect the two serial ports. it is about 1 meter long. On unit "pd 2801" with ip 192.168.11.66 AL is lit, CD is not lit. On unit "ds 2801" with ip 192.168.11.67 AL is lit, CD is lit. I defaulted both routers and entered configuration by hand based on examples I found on the net. The routers cannot ping each other. Here is show ver, show diag, and show run on both units. Can someone please suggest revision to my configuration? Thanks!!!! ----------------------------------------------------------------------------------------------------------- information on pd2801 pd2801#show ver Cisco IOS Software, 2801 Software (C2801-IPBASE-M), Version 12.3(11)T5, RELEASE SOFTWARE (fc1) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2005 by Cisco Systems, Inc.
