Caveats for Cisco IOS Release 12.0

Resolved Caveats—Cisco IOS Release 12.0(13)

There is no workaround.

• CSCdp95498

Ciscoview 4.2 might not work properly on a Cisco 7513 router that is running Cisco IOS Release

12.0(9). This situation occurs when slots 0, 2, 5, and 9 are populated with VIP2 Versatile Interface

Processors and PA-8T-V35 port adapter cards. CiscoView 4.2 might not show the PA-8T-V35 port

adapter on slot 9. Other slots might also report incorrect information. This situation is caused by

Simple Network Management Protocol (SNMP) agent, not CiscoView 4.2. The output of the

snmpwalk command shows the wrong cardType with a note indicating that indices 19 and 24 are

"unknown." There is no workaround.

• CSCdr50614

An NM-2E2W, NM-1E2W, NM-1E1R2W network module with a BRI WAN interface card (WIC)

and a WIC-T1CSU on a Cisco 3600 series router might function incorrectly on rare occasions.

When this problem happens, ISDN layer 1 on the BRI WIC is persistently deactivated and the

WIC-T1CSU continues to work corrrectly (if no event requires the integrated CSU/DSU to signal

the main IOS, in which case it ceases to pass date) except that the show service-module serial

privileged EXEC command returns an error message.

Workaround: Power cycle the router.

Alternate workaround: Reload software.

• CSCdr68325

A Cisco 7500 series router that is running encryption in Cisco IOS Release 11.2 might experience

spurious access and a software-forced reload after displaying the following log messages:

Crypto engine 4: sign message using crypto engine: %SYS-2-NOBLOCK: idle with blocking

disabled -Process= "Crypto SM"

There is no workaround.

• CSCdr76238

The VLAN0 of a Route Switch Module (RSM) participates in Open Shortest Path First (OSPF)

election. There is no workaround.

• CSCdr83309

Cisco Encryption Technology (CET) fails when you try to connect a third peer in a hub and spoke

topology and two active connections are already up . When one active connection is dropped, the

third peer is able to connect. There is no workaround.

• CSCdr92559

A new Hot Standby Router Protocol (HSRP) message type introduced in Cisco IOS

Release 12.1(3)T causes the STANDBY-3-BADAUTH error message to be displayed periodically.

This does not affect the operation of HSRP, and the message can be ignored.

Workaround: Upgrade to Cisco IOS Release 12.0(13).

Wide-Area Networking

• CSCdr07506

On a Cisco router, routes on multipoint subinterfaces are not learned within 360 seconds when

static map is not configured.

Workaround: Configure static map using the frame-relay map interface configuration command.
