I'm not sure you can trunk vlans across diffarent manufacturers.

on the cisco you need to set trunk mode on blade/port and set type. if you can set same type on both switches then the trunk should come up

I just replaced cisco 4506 with new 4506-e, the uplink port didn't work for trunking


Hi, if you installed a Supervisor 6L-E 10GE (X2) in the new 4506-E and you want to use the two 10GE uplinks as Gigabit, you need to type in the following config lines:

hw-module module 1 port-group 1 select gigabitethernet
hw-module module 1 port-group 2 select gigabitethernet

Make sure that the frame encapsulation is set on the router to 802.1q on each of the sub-interfaces. You could also try fixing the speed and duplex on both the router and the switch in case there is a problem negotiating the speed and duplex.

Hope that helps!

How can configure trunk


not sure about the 3COM side, but on the Cisco side... go to the configure prompt, then the port that you need to trunk (int [interface name and number] and enter)

Once you are in the interface, use the following command:
switchport trunk encap dot1q
switchport mode trunk

Then make sure that the interface is not shut down, connect the switches together and (hopefully) the 3COM will negotiate to trunking... if not you will need to manually configure the 3com.

Hope that this helps!

Lucent Cajun not talking to cisco catalyst


Not sure what Cat switches you have, but the cajun switch must use the same trunking encapsulation.  Older catalyst switches use ISL trunking which only work with Cisco switches.  Make the port between the lucent and cisco dot1q encapsulation on the cisco trunk port.  Also turn on debugging on the cisco and see what messages are generated.

LINKSYS SWITCH


No. You will create a bridge loop. The only way to do this is if you have a smart switch capable of aggregating multiple ports into a virtual trunk.

Cisco error on switch


%SYS-4-P2_WARN: 1/Tag 0 The switch generates %SYS-4-P2_WARN: 1/Tag 0… messages.
This example shows the syslog output that you see when this error occurs:
%SYS-4-P2_WARN: 1/Tag [dec] on packet from [ether] port [chars],
but port's native vlan is [dec] This message indicates that an 802.1Q-tagged packet was received on a nontrunk port. The VLAN that is derived from the packet tag is different from the port native VLAN. In the error message:
  • The Tag [dec] is the VLAN identifier from the packet.
  • The [ether] is the host MAC address.
  • The port [chars] is the port identifier.
  • The second [dec] is the native VLAN number.
There is a possibility that the local port is incorrectly configured as an access port instead of a trunk port. Alternately, the remote side can have been configured as a trunk port instead of an access port.
Verify that the local port is not incorrectly configured as an access port instead of a trunk port. Also, verify that the remote side is not configured as a trunk port instead of an access port.
