Thanks for the inputs.
Am having just 2 vlans(plus vlan1) and connecting one fast
ethernet port of nortel with one fast ethernet port of
cisco.
trunking on cisco is set to ON.
this port of nortel which is connecting to cisco is made a
tagged member of all the vlans inclusing vlan 1.
still i am not able to get connectivity between the two
vlans.
Thanks
Murali
