Caveats for Cisco IOS Release 12.0

Resolved Caveats—Cisco IOS Release 12.0(4)
• CSCdm05685
A Cisco router might reload if DLSw priority peers and Downstream Physical Unit (DSPU) over
virtual data-link control (VDLC) are configured together. This condition also occurs when DLSw
priority peers and Systems Network Architecture (SNA) over VDLC are configured together.
Workaround: Use regular DLSw peers.
Interfaces and Bridging
• CSCdj54192
An interface on a HSSI 1 port adapter (PA-H or H1T+) might go down/down and display the
following error message (XXXX represents the affected interface):
%MUSELIX-1-STOPFAIL: XXXX: Stop Failed at disable port
%MUSELIX-1-STARTFAIL: XXXX: Start Failed at enable port MUESLIX-1-FAILURE_CAUSE:
SerialX/X:
Issuing the shutdown and no shutdown commands has no effect. There is no workaround.
• CSCdk33589
A router might reload when traffic shaping is configured on an ATM interface. There is no
workaround.
• CSCdk47517
When a four-Port Token Ring 4/16-Mbps port adapter (PA-4R) is used on a congested or unclean
Token Ring, the VIP port adapter might exhibit the following errors and traceback:
> Sep 17 14:04:26 EDT: %IPC-5-SLAVELOG: VIP-SLOT4: > IBM2692-1-SRBQ_OVERFLOW: IBM2692
(0/0), SRB queue overflow. > Sep 17 14:11:03 EDT: %LINK-3-UPDOWN: Interface

There is no workaround.
• CSCdk52565
If you use a Cisco 7500 series router, a CT1/CE1 port adapter, PPP distributed hardware or software
compression, and Cisco IOS Release 11.2 P or below in conjunction with a remote router running
PPP software compression and Cisco IOS Release 11.3 or greater, a reload in LZS_Decompress, or
an “output stuck” error message might occur on the Cisco 7500 series router.
Workaround: Run Cisco IOS Release 11.2 P (or below), or Cisco IOS Release 12.0 (or above), on
both routers.
• CSCdk69514
The Ethernet interface of a Cisco 2600 series router that runs Cisco IOS Release 12.0 might not
come back up when the interface is flapping.
Workaround: Issue the clear int command.
• CSCdk77411
Although a Bridge-Group Virtual Interface (BVI) can receive Internetwork Packet Exchange (IPX)
packets, BVI cannot send IPX packets. There is no workaround.
