Resolved General Caveats in Release 12.1(23)E1
• SNMP traps are sent for every Internet Key Exchange (IKE) timeout and rekey but not for every
IPsec timeout and rekey. This situation might generate many false alerts that an IKE tunnel is down
when the IKE tunnel is torn down but immediately rebuilt. Releases where CSCee91044 is resolved
do not send SNMP traps that are sent for normal IKE operation. This problem is resolved in
Release 12.1(23)E1. (CSCee91044)
• A specifically crafted Transmission Control Protocol (TCP) connection to a telnet or reverse telnet
port of a Cisco device running Internetwork Operating System (IOS) may block further telnet,
reverse telnet, Remote Shell (RSH), Secure Shell (SSH), and in some cases Hypertext Transport
Protocol (HTTP) access to the Cisco device. Telnet, reverse telnet, RSH and SSH sessions
established prior to exploitation are not affected.
All other device services will operate normally. Services such as packet forwarding, routing
protocols and all other communication to and through the device are not affected.
Cisco will make free software available to address this vulnerability. Workarounds, identified below,
are available that protect against this vulnerability.

This problem is resolved in Release 12.1(23)E1. (CSCef46191)
• In an MPLS VPN provider edge (PE) configuration, for prefixes with multiple paths, some of which
are on an OIRed switching module, the local label for a prefix in the label forwarding information
base (LFIB) might be different from the local label allocated by the Label Distribution Protocol
(LDP). To display the LFIB local label, enter the show mpls forwarding prefix command. To
display the LDP-allocated local label, enter the show mpls ldp binding prefix mask length
command. This problem is resolved in Release 12.1(23)E1. (CSCee72857)
• After you enter a shutdown command on a physical ATM interface, ATM subinterfaces configured
on the physical ATM interface are displayed as “down” instead of “administratively down.” This
problem is resolved in Release 12.1(23)E1. (CSCea92873)
• Configuring an extended Border Gateway Protocol (BGP) community-list statement with any illegal
regular expression pattern might cause a reload. This problem is resolved in Release 12.1(23)E1.
(CSCdx71842)
• A memory leak might occur with Cisco IOS firewall authentication proxy configured. This problem
is resolved in Release 12.1(23)E1. (CSCef14971)
