I have a Nortel Passport 8600 and am trying to connect a 2950/24 to it using multiple links for redundacy. This is just a test to see if it will work. We are planning on upgrading our closet switches in a few months with 3750's and I want to be able to have multiple uplinks to the 8600. I can't seem to get this to work. Here are my commands from the Cisco switch. I can provide information from the 8600 if needed.
interface Port-channel1
no ip address
interface FastEthernet0/1
no ip address
duplex full
speed 100
channel-group 1 mode passive
!
interface FastEthernet0/2
no ip address
duplex full
speed 100
channel-group 1 mode passive

seems you need an additional command "channel-protocol lacp"
interface Port-channel1
no ip address
interface FastEthernet0/1
no ip address
duplex full
speed 100
channel-protocol lacp
channel-group 1 mode passive
!
interface FastEthernet0/2
no ip address
duplex full
speed 100
channel-protocol lacp
channel-group 1 mode passive
!
Also if you use passive on Cisco switch, make sure that it's active on Passport.

Sorry for the late reply. I have tried the protocol lacp command. Currently I have the Cisco swithc setup with the following.
interface FastEthernet0/23
no ip address
channel-group 1 mode active
channel-protocol lacp
On the Nortel switch there is no way that I see to configure active or passive. The tech I am working with said that it is active by default. One thing on the Nortel switch, you have to configure a lacp key. I have set this key value to 1 on the 8600 but don't see any way to set it on the Cisco. When I do the command show lacp 1 neighbor I get the following which has partner oper key listed. Since there is a standard for 802.3ad I would think this would be alot easier to setup.
Switch#show lacp 1 neighbor
Flags: S - Device is sending Slow LACPDUs F - Device is sending Fast LACPDUs
A - Device is in Active mode P - Device is in Passive mode
Channel group 1 neighbors

I am not sure that your problem is solved or not. I had the same problem one month ago between Nortel 8600(MLT) and cisco 2950(FastEC).
Nortel tech provides us a procedure which describes step-by-step configuration with MLT and etherchannel on these devices. If your problem persists I can supply the same document to you.
