Resolved Caveats—Cisco IOS Release 12.0(7)
• CSCdm48366
When entering the crypto-map map-name command on a Versatile Interface Processor (VIP)
interface, you must use a name that is not a subset of another crypto map’s name. For example, the
interface recognizes “testtag1,” “testtag10,” and “testtag100” as the same crypto map names. There
is no workaround.
• CSCdm51060
When software compression is configured on a Cisco 7200 series router on an interface configured
for Cisco Express Forwarding (CEF) or NetFlow switching, the router might experience a bus error
failure and reload. This situation occurs because CEF and NetFlow switching are not disabled when
compression is configured even though compression is not supported in CEF, NetFlow, or any
fast-switching mode on a Cisco 7200 series router.
Workaround: Explicitly disable CEF or Flow switching on the interface configured for compression
by entering the no ip route-cache {cef | flow} command.
• CSCdm59007
The Systems Network Architecture (SNA) packets might not be forwarded over a 64k leased line
with High-Level Data Link Control (HDLC) encapsulation. There is no workaround.
• CSCdm63884
A Cisco router might systematically reload with an error message if “num-exp 1* *” is configured
on the router. There is no workaround.
• CSCdm68773
A Cisco router might reload when the Cisco Service Manager (CSM) tries to allocate modems from
a different pool. There is no workaround.
• CSCdm68811
Hot Standby Router Protocol (HSRP) does not work if Inter-Switch Link (ISL) encapsulation is
configured. The active router does not respond to an Internet Control Message Protocol (ICMP)
ping of the virtual IP address.
Workaround: Load a new image that contains a fix for this problem.
• CSCdm68862
Hot Standby Router Protocol (HSRP) does not work when IP Protocol Independent Multicast
(PIM) is configured on a Fast Ethernet interface that uses the DEC211140 chipset. The active router
does not reply to an Internet Control Message Protocol (ICMP) ping of the virtual IP address.
Workaround: Use the burned-in address by entering the standby use-bia command.
• CSCdm69227
A Cisco 2600 series router that is running Cisco IOS Release 11.1(27)CC, 11.1(27.01)CC,
11.002(019.001), 11.2(19.01)P, 12.0(05.04)PI06, 12.0(05.05)S, 12.0(05.05)T, 11.2(19.01)BC,
11.1(27)CT, 12.0(05.05)SC, or 11.1(27.01)CT might exhibit the following rate-limited error
message:
%LINK-2-INTVULN: In critical region with interrupt level=1, ...
The router should continue to function normally. There is no workaround.
• CSCdm70085
A Cisco router running Cisco IOS Release 12.0(5.4) encryption image might reload if you enter the
crypto cisco pregen-dh-pairs command. There is no workaround.
