Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
• When there is insufficient memory, crash information is not generated after a Supervisor Engine
reload. This problem is resolved in Release 12.1(20)E. (CSCeb51785)
• Cisco 7603 switches running Cisco IOS Release 12.1(19)E and using 950 Watt DC power supplies
might keep modules in a power-deny state. This problem is resolved in Release 12.1(20)E.
(CSCeb57796)
• Ethernet interface counters are updated only at 10-second intervals, instead of in real-time and on-
demand. This problem is resolved in Release 12.1(20)E. (CSCec02790)
• An autonomous system border router (ASBR) might not update the forwarding address in
self-generated LSAs if the interface with the forwarding address was removed from the OSPF
domain. This problem is resolved in Release 12.1(20)E. (CSCdt45079)
• A Cisco 7200 series router may experience a memory leak caused by the Border Gateway Protocol
(BGP) I/O process. This problem is resolved in Release 12.1(20)E. (CSCdu43164)
• Non-facility associated signaling (NFAS) E1 or T1 ISDN calls that arrive on B-channel 16 (for E1)
or 24 (for T1) are not purged from the call history when the call disconnects; the calls are still shown
as active. This situation can cause the ISDN process to consume large amounts of memory. This
problem is resolved in Release 12.1(20)E. (CSCdv00338)
• A router may send linkUp traps with the loclfReason attribute set as “Down” and linkDown traps
with the loclfReason attribute set as “Up.” This problem is resolved in Release 12.1(20)E.
(CSCdv46906)
• The CISCO-MEMORY-POOL-MIB gives the wrong value for ciscoMemoryPoolType. This
problem is resolved in Release 12.1(20)E. (CSCdv55144)
• The counters in the show ip ospf output are not being reset correctly when the process is cleared.
This problem is resolved in Release 12.1(20)E.(CSCdv63847)
• When you enter the ip tcp path-mtu-discovery command on a router connected to an MPLS
network, the BGP session times out. This problem is resolved in Release 12.1(20)E. (CSCdv89098)
• OSPF might not set nonzero forwarding address in external default LSA. This problem is resolved
in Release 12.1(20)E. (CSCdw47949)
• If an IPsec peer receives an ISAKMP keepalive packet while keepalive is not locally configured on
the router, the following message is generated:
%SYS-3-MGDTIMER traceback
This problem is resolved in Release 12.1(20)E. (CSCdw58489)
• The connectionless network service (CLNS) to DecNet translation process causes packet corruption.
This problem is resolved in Release 12.1(20)E. (CSCdw79785)
• CLNS routes are not advertised on aggregation routers. This problem is resolved in
Release 12.1(20)E. (CSCdw83966)
• When OSPF is redistributed into any distance vector protocol such as RIP or EIGRP, OSPF does not
correctly process the command to remove the network. This problem is resolved in
Release 12.1(20)E. (CSCdx17429)
• IOS server load balancing (SLB) does not inspect RADIUS attributes before destroying the
framed-IP sticky database object. This problem is resolved in Release 12.1(20)E. (CSCdx70212)
• The multicast route monitor (MRM) test receiver intermittently reports false packet loss. This
problem is resolved in Release 12.1(20)E. (CSCdy03612)
• Distance vector multicast routing protocol (DVMRP) does not advertise the proper routes. This
problem is resolved in Release 12.1(20)E. (CSCdz08348)
