Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
developed by the University of Oulu to target this protocol and identify vulnerabilities. Support for
the H.323 protocol was introduced in Cisco IOS Software Release 11.3T, and all later Cisco IOS
releases are affected if configured for various types of Voice/Multimedia Application support. The
vulnerabilities can be exploited repeatedly to produce a denial of service (DoS). There are
workarounds available that may mitigate the impact, but these techniques may not be appropriate
for use in all customer networks. This advisory is available at:

This problem is resolved in Release 12.1(13)E12. (CSCea46342, CSCdx76632, CSCin56408,
CSCdx40184, CSCec76776)
• When there is insufficient memory, crash information is not generated after a Supervisor Engine
reload. This problem is resolved in Release 12.1(13)E12. (CSCeb51785)
• The system resets when the AAA protocol is configured for accounting. This problem is resolved in
Release 12.1(13)E12. (CSCeb42177)
• With Multicast Source Discovery Protocol (MSDP) configured, a reload might occur if you enter
the show ip msdp peer ip_address advertised-SAs command. This problem is resolved in
Release 12.1(13)E12. (CSCec23559)
• An IGMP packet flood might cause a reload. This problem is resolved in Release 12.1(13)E12.
(CSCec39132)
• A reload might occur when a TCP session is cleared. This problem is resolved in
Release 12.1(13)E12. (CSCdw76948)
• With the Protocol Independent Multicast (PIM) Dense-Mode State Refresh feature enabled, a reload
might occur if the group mode changes from PIM dense mode to PIM sparse or bidirectional mode.
This problem is resolved in Release 12.1(13)E12. (CSCea09302)
• With Layer 2 protocol tunneling configured, VTP traffic might be incorrectly dropped by IEEE
802.1Q tunnels. This problem is resolved in Release 12.1(13)E12. (CSCec11165)
• OIR of a fabric-enabled switching module might cause a reload. This problem is resolved in
Release 12.1(13)E12. (CSCec12236)
• A reload might occur if you modify a policy map that is attached to an interface. This problem is
resolved in Release 12.1(13)E12. (CSCec15119)
• With EoMPLS configured, a reload might occur if you configure a different access VLAN on the
CE-facing port. This problem is resolved in Release 12.1(13)E12. (CSCec23787)
• A FIB-related memory leak might occur. This problem is resolved in Release 12.1(13)E12.
(CSCec43573)
• With VLAN aging configured, the routed MAC (RM) bit might be set on the Layer 2 entries for
routed traffic, which causes the entries to be purged every 5 minutes. One packet might be flooded
and relearned for each purged entry. This problem is resolved in Release 12.1(13)E12.
(CSCec43605)
• With a large number of static multicast entries configured (approximately 8,000), some entries
might not propagate to DFCs. This problem is resolved in Release 12.1(13)E12. (CSCec50577)
• L3-PS-DRVR messages are seen every 12 to 16 seconds. This problem is resolved in
Release 12.1(13)E12. (CSCec63833)
• For BGP routes learned through a WAN interface, if the BGP neighbor goes down, the default route
adjacency does not change if the default route learned through BGP had a better metric than a static
route configured locally. This problem is resolved in Release 12.1(13)E12. (CSCec41005)
