PVC in IMA group become INACT after IOS Upgrade 12.3(17b)

Hi all,

on a cisco 7204VX running a IOS image c7200-is-mz.121-14.E10.bin

I have a 8 port E1 IMA port adapter with pvc

configured in a IMA group.

Here is part of the working configuration:

----------------------------------------------------------------------------------------------

interface ATM2/0

no ip address

scrambling cell-payload

framing crc4adm

ima-group 1

!

interface ATM2/1

no ip address

scrambling cell-payload

framing crc4adm

ima-group 1

!

interface ATM2/ima1

description

mtu 1500

bandwidth 8000

no ip address

no atm auto-configuration

no atm ilmi-keepalive

!

interface ATM2/ima1.111 point-to-point

ip address 10.254.99.61 255.255.255.252

pvc 10/111

ubr 1536

I tried to upgrade the IOS to image c7200-is-mz.123-17b.bin, as a result all of the PVC became inactive, so after some try I needed to downgrade to old image to have it working again.

Please can anybody tell me what have I to do to

have it working on a 12.3 IOS image?

Thanks in advance,

Marco.
