A client is running a 2600 series router with an NM-4T1-IMA (4 port ATM T1) card in it. When the router was running 12.0.?T, the ATM interfaces were showing just fine. We had to upgrade the IOS because of an EIGRP issue. The router is now running 12.2.7c. After the IOS upgrade, the ATM interfaces disappeared. When doing a show ver, we get:
cisco 2611 (MPC860) processor (revision 0x203) with 58368K/7168K bytes of memory.
Processor board ID JAD043707AE (4180082506)
M860 processor: part number 0, mask 49
X.25 software, Version 3.0.0.
2 Ethernet/IEEE 802.3 interface(s)
32K bytes of non-volatile configuration memory.
8192K bytes of processor board System flash (Read/Write)
The ATM interfaces used to show up here. We're still running bootstrap 11.3(2)XA4.
