Hello Subhojit,


an etherchannel using LACP  is the recommended solution.


This solution can be used if the two links are between the same two devices.


note:

on cisco side you can consider like a single box a stack of 3750 / 3560 or a VSS pair of two C6500



example config (cisco side)


interface gi0/x

switchport

shut

switchport trunk enc dot1q

swichport mode trunk

switchport trunk allowed vlan X,Y,Z

channel-group 5 active



interface gi0/y

switchport

shut

switchport trunk enc dot1q

swichport mode trunk

switchport trunk allowed vlan X,Y,Z

channel-group 5 active


later you can enable both at the same time using


interface range giga 0/x - y

no sh

!

similar configuration has to be done on nortel side


X.Y,Z are just example of vlans to be permitted on the trunk

I' ve used channel-group 5 but it is just an example


you can use

sh etherchannel summary

to find what bundles are active on your system you need to use an unused group number



at the end the same show can tell you if the new bundle is fine


Hope to help

Giuseppe
