I have the following problem regarding a fallback bridging deployment:
I already configured the switch to support fallback bridging as follows:
interface vlan 2
ip address 18.104.22.168 255.255.255.0
interface vlan 3
ip address 22.214.171.124 255.255.255.0
bridge 1 protocol vlan-bridge
I have correctly assigned vlans to switched ports, the following is happening:
when I first configure bridging on the switch my users on vlan 2 cannot access a server on vlan 3 (netbeui protocol), after reloading the switch without making any changes on the user computer or the server the user is able to access the server and all the services needed, but if the user reboots the computer when it tries to log again in the system is unable to find the server and services.
It seems to be that fallback bridging is only working once after reloading the switch.
A customer is experiencing a similar issue with IPX, on a 3550-EMI running 12.1(13)EA1a. Removing and re-applying the bridge-group seems to fix the problem for a few days. Might be enough to help you until the fix comes out.
