SRW2048 Trunking issue

I have a string of switches trunked together, all the VLANS on the different switches work together fine. but the issue is with the management interfaces of any switch "downstream" of the srw2048, the map is Router---->Srw2048---->3750ps---->2960 each of these switches has the same 5 VLANS configured.
The srw2048 is 192.168.1.254
The 3750 is 192.168.1.252
the 2960 is 192.168.1.250
I can get to the srw2048 management interface, but not the 3750 or 2960. If I connect a device to an access port on any switch, it is assigned an IP and functions properly on the network.
If I remove the swr2048 and just use the 3750 and 2960, the two hosts can talk fine, so I think I have a configuration problem on the srw2048. I have the uplunk from the srw2048 to the 3750 set as a Trunk and all VLAN membership.
Do I need to use the LAG function in the srw2048? I'm not sure what I'm missing here.

Hi,
so the trunk 802.1q concept requires to have VLAN untagged with PVID and the other must be tagged. That should match on both ends.
General mode allows basically any settings. Basically all the packet with VLAN tag would be forwarded as per tag and those packets with no tag should be classified as per PVID. Perhaps the management VLAN on the other end of the trunk is not tagged...
can you tell me what are the detailed settings on both ends?
such as 100T, 200T, 1P etc

SRV3000 Trunking Issues

Issue:
Need some assistance configuring 3 aditional lines on my SRV3000, There are two lines that are working fine but when trying to add 3 new ones, It was unable for them to work. Provider explained that this is a Trunking issue, The three aditional lines state they belong to Trunk 9-DID Any suggestions?
Thanks in advance.

Hi Juan,
Do you mean a Linksys One SVR3000?
If so, this is a specialized services router that was designed to only work in the Linksys One environment registered to a Service Node.
I can't offer any help with this device.

Trunking issue with autonomous AP

I was at a customers that wanted a new ssid configured on his 20 1252 AP's and to stand up a new one with the olds and new SSID on it. Added the vlans, trunked them down and configured the interfaces and SSID's on the existing AP's no biggie. The new AP(not really new been kicking around in a lab) is giving me some weird issues. I deleted the exisiting config from it and took one of the running configs fromm the others that are working, modified the name and ip and pasted it in. This should have worked just fine. However the trunk port on the 4507 will not come up. The radio's are up and so is the BVI, however I cannot ping to it since the trunk is down. I started looking at the config and the thing I notice is that the AP's are in vlan 2, and the native vlan is set for vlan 2 on all the working trunk ports on the switch. However the AP's do not have vlan 2 on them, and their native vlan is 1. This should not work! I always thought the native had to match on both sides?? In any case I am probably missing something stupid, I have been up since 4am it was a 4 hour drive to get here. Oh and I have to go back and make firewall changes at midnight. Here is the relavent configs please let me know if its something stupid I usually do a lot of controller based installs havnet done a autonomous one in years. Thanks!

Hello Mike,
actually, native VLAN doesn't have to match on two sides of a trunk, in fact it's quite common with autonomous APs. Your BVI1 is usually tied to a native VLAN 1, but switch port native VLAN is usually configured for whatever VLAN you want AP's management IP to belong to, in your case VLAN 2.
When you connect two catalyst switches together with a trunk that has different native VLAN configured on two sides, you will keep getting logging messages warning you about it. It's not recommended, but some scenarios require such setup.
Something else is wrong, maybe a physical issue. When you say the trunk is down, do you mean the interface is down ? Can you paste config of bad switch port and bad AP?

NAC Appliance + OOB Virtual Gateway Trunking issues

I have the following problem. When I connect the CAS eth0 to a trunk port in the core switch it disconnects from the CAM. When the port is in access mode, the CAM can connect to the CAS. The core switch is a 4500 with IOS 12.2(25)EW. What could be the problem?

Hi prananth,
I managed to resolve the issue. It was a HA issue. I had configured "Link failure detect" on the redundant CAS app. Apparently the CAS couldnt reach the pingable IP causing failover to take place many times between the two boxes causing the CAS not to communicate with the CAM.
Kindly help me with the following problem I am now having:

Trunking issue

Hi Everyone,
I just need a clarity on one issue. We have a scenario where we have 2 basestations with Cisco 2950 series switches. There is layer 2 connectivity on bridged mode in between the 2 basestations.
a<--->b<---->NOC
The connectivity between b and NOC is also on layer 2 via bridged mode.
there is a requirement of trinking the ports that cross connect the switches thru wireless bridged mode.At the extreme most end at noc the port is in access-mode. The switch at NOC is extreme summit 48 si.
When i tried to make the port at switch b in trunk mode i lost the vty access.
Please suggest as to what an be the reason since a trunk port should also allow untagged traffic.

Hi ER,
Trunk port bydefault allow only vlan 1 as native vlan which will be send across the trunk without tagging.

Ankur

SRW2048 - trunk port

Hi,
I have a question according trunk port behavior.
I need to connect Cisco Linksys to a Catalyst switch. On the Catalyst I have set up the port to trunk mode.
I have also put the SRW2048 port to trunk mode. But the switches are not able to communicate to each other.
Is there any possibility to set up on the SRW2048 to accept all tagged vlans on the trunk port. Because it looks like
to be a bit different behavior from cisco switches where are all vlans available on the trunk mode port.
I am talking about encapsulation dot1q (tagged Vlans)
The switch has teh newest firmware: v1.2.2d
Thank you for your response.
Juraj

Unlike the Catalyst, the SRW does not automatically add all VLANs on the switch to a trunk port. Instead you have to make all your VLANs member of the trunk mode port.

4500X VSS Trunking issue

Hi,
I am having an issue that the VSS is different for each switch and the trunking is not working, is there anyway to configure the trunking on the VSL port without breaking the VSS? I have set the trunking on both switches but somehow after the VSS connection is up the trunking is removed on the switch 2. The following are the snippet of the VSS configuration:
Switch 1:
interface Port-channel1
description *** VSS Port-Channel 1 ***
switchport
switchport mode trunk
switchport nonegotiate
switch virtual link 1
interface TenGigabitEthernet1/2/8
description *** VSS Links ***
switchport mode trunk
switchport nonegotiate
no lldp transmit
no lldp receive
no cdp enable
channel-group 1 mode on
service-policy output VSL-Queuing-Policy
Switch 2:
interface Port-channel2
switchport
switch virtual link 2
interface TenGigabitEthernet2/2/8
no lldp transmit
no lldp receive
no cdp enable
channel-group 2 mode on
service-policy output VSL-Queuing-Policy
Now I only have limited command on the Port-Channel 2:
SWITCH01(config)#int po2
SWITCH01(config-if)#?
virtual link interface commands (restricted):
default Set a command to its defaults
description Interface specific description
exit Exit from virtual link interface configuration mode
load-interval Specify interval for load calculation for an interface
logging Configure logging for interface
no Negate a command or set its defaults
service-policy Configure CPL Service Policy
shutdown Shutdown the selected interface
switch Configure switch link
Thanks in advance for any helpful comment.

Hi,
You don't need to configure the VSL link as trunk:
just follow this config example:
Switch-1(config)# interface port-channel 10
Switch-1(config-if)# switch virtual link 1
Switch-1(config-if)# no shutdown (If the port is admin shutdown)
Switch-1(config)# interface tenGigabitEthernet 5/1
Switch-1(config-if)# channel-group 10 mode on
Switch-1(config-if)# no shutdown (If the port is admin shutdown)
Switch-2(config)# interface port-channel 25
Switch-2(config-if)# switch virtual link 2
Switch-2(config-if)# no shutdown (If the port is admin shutdown)
Switch-2(config-if)# interface tenGigabitEthernet 5/2
Switch-2(config-if)# channel-group 25 mode on
Switch-2(config-if)# no shutdown (If the port is admin shutdown)

WLAN 4400 - Trunking issue

Hi all,
We are having an issue setting up a truck port for the 4400 to our 2950 swithes.
The setup will work fine without vlan tagging. The WLAN controller can ping the switch and our network.
When I configure trunking on the switch, the connection drops.
I have configured the Gi 0/2 port with the below commands
interface gi 0/2
Switchport trunk allowed vlan 1-10
switchport mode trunk
No shut
Modifying the WLAN 4400 I set the management interface tagged for vlan 2.
This breaks the connections between the WLAN controller and the switch.
Can you advise where I may be going wrong and how to rectify.

Hi fella5 :
First , Thx your idea.
All vlans configured to the switch and all the Layer3 interface configured for each one .
DHCP scope work fine .
The PC client can associate to the AP successfully when i change the interface to other vlan at WLAN interface.But the AP group just not work.
by the way , would you mind tell me how i can assign the ap group to each radio ?

Vlan Trunking issue

Hi,
I need some help setting up L3 Cisco 3560 for my VM lab. I have setup a few vlans and at this point I am trying to test out routing and connectivity. I came across with two issues and I am trying to get good advise from the experst since I am not
The Cisco 3560 is directly connected to my home router gi0/4 192.168.10.0/24 which would be my internet connection. The home router default gateway is 192.168.10.1.
I created Vlan192 on the 3560 to interact with the home router and get me to the outside world from the core. Obviously I'm doing something wrong here and came across 2 issues.
1- I tried setting Fas0/2 as trunk port and using the vlan226 on my pc but it wont work when I set this to my computer. It wont route to all vlans and I am not able to ping this 10.23.226.9 address from the 3560. The only way this works for me is if I set the IP to the 192 range which is my native Vlan, but anything other from 192 wont route.

VTP trunking issues

I have a VTP domain with approximately 70 VLANS. Some of our older switches are only capable of handling 64 VLANS and therefor switched from VTP Server to VTP Transparent when the limit of 64 VLANS was reached. I need to configure some of those older switches for newly added VLANS.
I have since limited the VLANS that are allowed on the trunk link (on both sides) and deleted some of the disallowed VLANS from the Transparent switch. I would like to turn the switch back to Server mode, but it immediately switches back even though it has less than 64 VLANS .
Is there any way to return this switch back to a VTP server?

If you are configuring the switch as a VTP server in a new domain, it should not be a problem but becoming the VTP server in an existing domain would mean that when you enter vtp mode server, the configuration revision number for that domain in that switch starts off at 0. In this case, it would recieve a vtp advertisement for the same domain from an existing server with a higher configuration number and overwrite the configuration you just created.
Try creating just one server and all others in client mode.

Cisco 2950 - 3350 Trunking issue - Port not lighting up

Hi There,
I have two switches I am trying to connect a 2950 and a 3350. I have a crossover cable connecting them from fa0/24 to fa0/24 setup as a trunk,
however they won't connect and the port on both switches is down, (e.g no port light coming on on switch)

WiSM Trunk Issue

Anyone know how to reset the WiSM to factory defaults? Troubleshooting FAQ suggests resetting WiSM and entering "recover-config" at the username prompt, but that did not work. I made a change to one of the gig ports and it brought down the port-channel that's dynamically configured during initial configuration. Since I can't restore the port-channel, I need to start over...

Depending on which version of IOS you are running, it should re-create the channels on its own.
if you back out the wism config commands on the switch, it should create the interface/channels for you.
no wism service-vlan xxx
no wism module x controller 1 native vlan xx
no wism module x controller 1 allowed vlans xx,xx
do for controller 2 as well
and then re-add them.
afterwards, do the following:
sho wism status
sh wism module x controller 1 status
sh ether-channel xxx (what the wism/720 created) summary

Dynamic Trunking Protocol and ports mode

((Dynamic Trunking Protocol (DTP), as the name implies, is the protocol used to automatically negotiate a trunk link.
DTP supports the auto negotiation of both ISL and 802.1q.
By default all ports on the Catalyst 3550 are dynamic desirable ports which will aggressively attempt to negotiate trunking through DTP.
To disable DTP and the auto negotiation of trunking, issue the interface level command switchport
nonegotiate)).
1- How many trunk mode have we got ? one of them is negotiation,,,Do we have any other ?
2- "By default all ports on the Catalyst 3550 are dynamic desirable ports".
2/a- Are there any other mode for ports ?
2/b- Is this different form one type of switch to another type ?

"1.Diff trunk modes are on,off,desirable,negotiate".
Does DTP decide which mode to be used (chose one out of 5)?
"2/a. Diff modes of ports are, access, trunk, dynamic desirable. "
does that mean the dynamic desirable can be either access or trunk port ?
I get confused between three different interface mode :
1- switchports----can be access and trunk ports
2- routed ports
3- switched-virtual interface
