Hi,
Any one created port-channels with Nortel 5500 switches at the edge i.e. with two 6500's running HSRP ? A config would be much appreciated
I am assuming LACP will be the protocol
much appreciated

Hi Saquib,
I helped a guy to create an LACP port-channel between a Nortel switch and a Cisco switch.
I guided him with the configuration of the Cisco side of the port-channel.
I can help you with the LACP configuration but not the Nortel switch specifics.
Please tell what exactly you need.

You say that your 6500's are running HSRP. Based on this i assume that you need a connectivity to both the 6500's but do you have dual connections to each of them to run LACP?
If you have a single link, STP will block one.
Cisco switches do not support SMLT which a nortel switch does and loadbalance traffic between 2 chassis at L2

I don't have an issue either creating it on the Cisco side or the Nortel side using LACP.
Instead of using MLT / SMLT on the 5500 switches, LACP is the compatible protocol between Cisco and Nortel.
Just wondering if someone has already done it and can share the configurations to confirm. I have it kinda running in a lab environment. It should be a common configuration.

Hi Saquib,
Here's a sample config I used for connecting a Cisco switch to a Nortel switch:
conf t
port-channel load-balance {load-balance method}
lacp system-priority 100
interface range gig2/11 - 14
switchport
switchport trunk encapsulation dot1q
switchport trunk allowed vlan x,y,z
switchport trunk native vlan x
switchport mode trunk
channel-protocol lacp
channel-group 1 mode active
The load-balance method depends on your traffic. Please read more about it on the link here:
Click on the "Configuring EtherChannel Load Balancing" link.
Load balancing can be based on the mac-addresses, ip addresses (on 6500 and 4500 switches on port numbers as well).

I do have the stuff working with LACP with both on the Cisco side and the Nortel side. Does anyone have a configuration from the Nortel side 5500 or 470 switch side, not 8600 ?
Another option, I am told if I use MLT on the Nortel side and Port-Channel on the Cisco side, I should be able to talk. Is that true, has anyone tried this without using LACP ?
