Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
• In a topology that uses VLAN interfaces for intermediate router connections, PIM register and PIM
register stop messages might loop between the intermediate routers until the TTL count expires.
This problem is resolved in Release 12.1(13)E7. (CSCea82353)
• With IP inspection configured, a reload might occur following an “%ALIGN-1-FATAL” message.
This problem is resolved in Release 12.1(13)E7. (CSCea51320)
• The switch might drop into ROMMON mode after reload. This problem is resolved in
Release 12.1(13)E7. (CSCea88910)
• Invalid 64-bit counter values instead of zero values may be returned for IF-MIB Layer 2 VLANs.
This problem is resolved in Release 12.1(13)E7. (CSCea59775)
• If a crash information file is written to an ATA Flash PC card, the file on the ATA Flash PC card may
be corrupt and unusable. This problem is resolved in Release 12.1(13)E7. (CSCdz81035)
• If the copy operation of an image file to a PC Flash card is interrupted by a system reload or a power
failure, the image file might be corrupted. If this image is later copied or used to boot the system,
the copy or boot process may fail and display a “sector read failed” error message. This problem is
resolved in Release 12.1(13)E7. (CSCdz54387)
• Multicast shortcuts take a long time to install during dense mode fallback, which causes latency in
hardware switching. This problem is resolved in Release 12.1(13)E7. (CSCeb14435)
• When you enter a shutdown command followed by a no shutdown command, or enter a clear ip
mroute command, the scan timer may not restart and multicast route entries may not be hardware
switched. This problem is resolved in Release 12.1(13)E7. (CSCea05404)
• Multicast entries may become inconsistent when configuration changes are made, such as modifying
an interface’s IP address. The multicast entries are programmed in the hardware, but the software
does not reflect the hardware state. This problem is resolved in Release 12.1(13)E7. (CSCea71130)
• User-configured static multicast MAC entries are not processed correctly. When the system first
boots, the interface state does not show up/up, and the interface does not get added to the Layer 2
table. Consequently, traffic is not received by the port. This problem is resolved in
Release 12.1(13)E7. (CSCea72405)
• On a system with a Supervisor Engine 2, a MSFC 2 and a DFC, when the DFC card is reset, traffic
is software switched for those ports that have HSRP enabled. This problem is resolved in
Release 12.1(13)E7. (CSCea89099)
• A default route learned through a routing protocol might be either missing or incomplete. This
problem is resolved in Release 12.1(13)E7. (CSCeb18552)
• If you enter a show cdp neighbor command on a switch connected to another switch with a port
channel, the command output may show the same local interface for all member ports in the channel.
This problem is resolved in Release 12.1(13)E7. (CSCea15655)
• When using stateful Cisco IOS server load balancing (Cisco IOS SLB) and with the standby
preempt command configured on some interfaces, a switchover to the redundant supervisor engine
might cause high CPU utilization. This problem is resolved in Release 12.1(13)E7. (CSCea54756)
• When the maximum number of RLB sticky subscribers for a real server (SSG1) are exceeded, the
RLB does not pass AcctStop packets (from GGSN) to SSG1 for the existing host objects, but to the
next SSG in the round-robin pool. The SSG proxies the AcctStop packets to the AAA server, which
then closes the corresponding RADIUS sessions. This situation leads to stale host objects on the first
SSG. This problem is resolved in Release 12.1(13)E7. (CSCeb09340)
• A reload might occur if you configure an IP address that is a duplicate of an IP address configured
on a redistributed BGP peer. This problem is resolved in Release 12.1(13)E7. (CSCdz30644)
