Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
• SSH Version 1 does not work. This problem is resolved in Release 12.1(20)E2. (CSCed47810)
• When the OSPF cost is changed on one of the upstream paths in the network and a request to delete
or remove the stale entry is not received, the TTFIB table contains stale entries that causes traffic
loss. This problem is resolved in Release 12.1(20)E2. (CSCed01611)
• A Catalyst 6500 switch with an MSFC
• Layer 2 traffic might be dropped if policy-based routing (PBR) is enabled on a VLAN interface. This
situation affects all traffic not permitted by the configured policy. This problem is resolved in
Release 12.1(20)E2. (CSCed05843)
• A Catalyst 6500 switch with an MSFC may drop Layer 2 traffic if policy-based routing is enabled
on the VLAN interface of the MSFC. This situation will affect all traffic not permitted by the
configured policy. This problem is resolved in Release 12.1(20)E2. (CSCed05843)
• A 512 MB small outline DIMM (SODIMM) registers as only 256 MB when you enter the show
diagnostic command. This problem is resolved in Release 12.1(20)E2. (CSCed07253)
• Weighted Fair Queuing WFQ over Frame Relay runs like first-in-first-out (FIFO). This problem is
resolved in Release 12.1(20)E2. (CSCed09383)
• Malfunctioning PIM, MLSM, or mwheel processes might cause “CPUHOG” and “WATCHDOG”
messages and reloads. This problem is resolved in Release 12.1(20)E2. (CSCed12393)
• Gigabit Ethernet negotiation does not work. This problem is resolved in Release 12.1(20)E2.
(CSCed19431)
• On the WS-6548-GE-TX and WS-6148-GE-TX modules, the functionality for the mls qos trust
ip-precedence and mls qos trust dscp commands is reversed. This problem is resolved in
Release 12.1(20)E2. (CSCed38413)
• A Catalyst 6500 series switch crashes when an exception is generated as the result of adding a
policy. This problem is resolved in Release 12.1(20)E2. (CSCed46684)
• A reload might occur when an exception is generated as the result of adding a policy. This problem
is resolved in Release 12.1(20)E2. (CSCed46684)
• When more than 12 VLOUs are used in a policy attached to an interface, the entries are expanded.
If the expanded entries are for a non-deny ACE, the entries are not accurate. The resulting ACEs for
the policy are also inaccurate. This problem is resolved in Release 12.1(20)E2. (CSCed47753)
• With a Supervisor Engine 2, when a fabric-capable line card comes online and an RSPAN source
session is configured, the RSPAN source session might stop working. When this happens, the traffic
being monitored will not be replicated on the RSPAN VLAN. This problem is resolved in
Release 12.1(20)E2. (CSCin61989)
• Occasionally, multicast traffic that should be completely Layer 3-switched is partially
Layer 3-switched, which causes multicast packets to be dropped when the ACL TCAM is full. This
problem is resolved in Release 12.1(20)E2. (CSCin63402)
• QoS access control list with Layer 4 port operation is not supported. This problem is resolved in
Release 12.1(20)E2. (CSCdx91720)
• The output rate bits per second value is incorrect. This value is consistently high and does not
correlate to actual traffic. This problem is resolved in Release 12.1(20)E2. (CSCeb33104)
• With an MPLS PE configuration, some IP-to-tag adjacencies might be incorrectly installed on the
switch processor after interfaces go up and down and a large number of BGP routes need to be
resolved. This problem is resolved in Release 12.1(20)E2. (CSCec30461)
