I have running 3640 with ATM IMA and everything is working ok. I must replace it with 7200, but when I try to move ATM IMA links to 7200, link is down with IMA status insufucient links.
Any ideas? Does anyone have sample config for ATM IMA on 7200
Thanks!

first of all, make sure that all physical parameters (Framing, linecode, scrambling, ...) are correct on the 7200 ATM interfaces. What is the status of the ATM interfaces on the 7200 ? What is that 7200 connected to ?

1. I do not know to what 7200 is conneted at provider side but following config is ok on my 3640, same physical lines

I get following status on ima group
Router#sh ima int atm1/ima1
ATM1/ima1 is down
ImaGroupState: NearEnd = startUp, FarEnd = insufficientLinks

Note that I cannot write ubr 2048 on pvc and that interfaces atm1/6 and atm1/7 looks ok if they are not in ima group, but after putting them in ima group I get following status

... and also i get following message durin router boot

%PA-3-DEACTIVATED: port adapter in bay [1] powered off.
bay 1 is a bay with ATM card

Hi,
A couple of things, verify with provider, sequence # on the t1's, it matters.
Secondly i did not see the ima group defined, try this
What's your total bandwidth? is it 2 E1's
interface ATM1/6
no ip address
scrambling cell-payload
framing crc4adm
ima-group 0
!
interface ATM1/7
no ip address
scrambling cell-payload
framing crc4adm
ima-group 0
interface ATM1/IMA0

It looks like you have an IMAM version mismatch. 7200 implements IMAM 1.1, but 3640 supports IMAM 1.0. So you need to call your provider and let them know you change to IMAM 1.0, they will probably need to restart the IMAM group in order to renegotiation take place between Router and switch (in some switches IMAM version should be change manually).
Unfortunately this is one part of the problem. In the old times when ATM Forum made the recommendation for IMAM development USA Vendors misinterpreted them. So there are 2 variants of IMAM 1.0 one apply by most of American Vendors and an other by Europeans. The differences are on how TX/RX Link IDs should be assign (you can read more about this at: Cisco Bug CSCdw74417). There are two possibilities to workaround this problem, some switches like Lucent SAX may be configure for any of the two variants. The other one is to connect port 1 of router with port 1 of switch, 2 with 2 and so on.
But in any case you need to call your provider and let them know, if you are unable to reach some one at your provider who understands about IMAM, just tell him to restart de IMAM group.

You need to have an Enterprise IOS to support IMA modules.

... or maybe problem is that on

"The PA-A3-IMA in a Cisco 7200 VXR router requires the NPE-300, 4 MB of SRAM,
and a minimum of 64 MB of DRAM"
and I have NPE-255
