What is the latest IMA protocol version running on a 3640 with IOS version 12.0(7)T

[admin_2]

I am having problems with a 3640 router running IMA to a Nortel Passport 15000. I need to verify that the 3640 is running IMA version 1.0

Actually, the specification depends

on the HW, not the IOS. In your case

I assume you are using the NM-4/8E/T1-IMA,

which does support 1.0.

Regardless, the IOS you are using can

be providing you with problems; the

support for this NM came in 12.0(5)T, so

you may consider upgrading (maybe try the

latest 12.1 mainline) to see if that helps.
