Hi, me again.
I am in the unhappy situation to renumber my vlans.
I would like to cross-connect (bridge) the old-vlans
with the new ones (without plugging cables)
so the client-ports may migrate smooth .
Problem are not the access-ports, but
when dot-q trunks go into a firewall or an esx-server.
The spanning-tree problematic has been solved already,
bpdu's must not be forwarded between old and new vlans.
So is there a way to configure it on Cisco Catalys switch
Enter configuration commands, one per line. End with CNTL/Z.
VLAN 200 TLB 1 VLAN value 501 have similar types (Ethernet)
APPLY VLAN changes failed.
This does not work,
and the switchport vlan map xxx to yyy port command for a trunk interface
seems not to be supported on my hardware.
Thank you for any hints,
