I have configured bridge-group for dlsw on a Fastethernet dot1q encapsulated subinterface.

on the switch I have seen the remote mac-address learned in vlan 1 (untagged vlan of the trunk) and I have not seen that mac-address on vlan 3 as it was aspected.

here is the configuration:


interface FastEthernet0/0

no ip address

duplex auto

speed auto


interface FastEthernet0/0.2

description lan SERVIZIO

encapsulation dot1Q 2

ip address


interface FastEthernet0/0.3

description lan UFFICIO

encapsulation dot1Q 3

ip address

ip helper-address

bridge-group 1


dlsw local-peer peer-id

dlsw remote-peer 0 tcp

dlsw icannotreach sap F0

dlsw bridge-group 1


bridge 1 protocol ieee

Hi Massimiliano,

Are you possibly using an older version of IOS? This was not supported until later versions (~13) of 12.2. Otherwise what you have looks OK.

Hi Dan,

thank you for your answer.

The problem was no longer seen changing the switch (a non-cisco switch was installed).

the ios is a 12.2-17a and it supports dlsw bridging on dot1q trunk.

thank you
