Caveats for Cisco IOS Release 12.0

Resolved Caveats—Cisco IOS Release 12.0(7)

• CSCdm72581

After continuously looping in nns_olu_cdinit_reply_processing, an Advanced Peer-to-Peer

Networking (APPN) router running Cisco IOS Release 11.2 might reload and exhibit the following

error message:

abort crashdump process_handle_watchdog signal_receive process_forced_here

nns_olu_cdinit_reply_processing

There is no workaround.

• CSCdm73345

A Cisco router running Advanced Peer-to-Peer Networking (APPN) might not respond to BINDs

or fail BINDs in sense 0x08150004. There is no workaround.

Interfaces and Bridging

• CSCdk60571

Serial interfaces and line protocols on Cisco 3600, 7200, and 7500 series routers might fail with all

physical control signals up, including data carrier detect (DCD).

Workaround: Perform a microcode reload.

• CSCdk66951

When you are configuring a new E1 PRI interface on a port adapter in a VIP2-based system, all

active E1 interfaces will fail even if those E1 interfaces are not on the same VIP2. There is no

workaround.

• CSCdk89313

In certain Cisco IOS releases there is currently no NetFlow support for Bridge-Group Virtual

Interfaces (BVIs) or any other interfaces in a bridge group. The resolution is to upgrade to a

Cisco IOS release that support this feature. There is no workaround.

• CSCdm28550

If the ATM interface on a Cisco 7000 series router receives an ATM adaption Layer 5 (ATM5)

packet of 66532 bytes, it might result in an internal zero length packet and cause the Versatile

Interface Processor (VIP) to reload. There is no workaround.

• CSCdm45222

An ATM interface on a Cisco router might drop Operation, Administration, and Maintenance

(OAM) packets and exhibit increasing ignores and drops with distributed Cisco Express

Forwarding (dCEF) and an input feature (such as Access Control List) configured. There is no

workaround.

• CSCdm61507

If you enter the show frame-relay pvc command on a Cisco router with FRF9 compression

enabled, the incoming packet count might be doubled, first in its compressed state and then in its

uncompressed state.

Workaround: Disable FRF9 compression.

• CSCdm69501

A Versatile Interface Processor (VIP) might reload with distributed Cisco Express Forwarding

(dCEF) switching locally between subinterfaces with different maximum transmission unit (MTU)

size on a PA-A1 port adapter.

Workaround: Do not use distributed switching.
