Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
• With Rapid-Per-VLAN-Spanning Tree (Rapid-PVST) or IEEE 802.1s multiple spanning tree (MST)
configured, when the root bridge in a spanning tree domain ages out, the remaining bridges
reconverge after timing out the root bridge. During this reconvergence, a spanning tree loop might
occur. This problem is resolved in Release 12.1(22)E. (CSCed00441)
• In releases where caveat CSCed00441 is resolved and with Rapid-Per-VLAN-Spanning Tree
(Rapid-PVST) or IEEE 802.1s, multiple spanning tree (MST) configured, when an edge port goes
down, a topology change is generated. This problem is resolved in Release 12.1(22)E.
(CSCed63897)
• Network Address Translation (NAT) does not work with WCCP configured. This problem is
resolved in Release 12.1(22)E. (CSCeb28941)
• 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(22)E. (CSCin63402)
• 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(22)E. (CSCin61989)
• The show controller serial command output is not complete. This problem is resolved in
Release 12.1(22)E. (CSCin60835)
• With fall-back bridging configured, ARP fails after a switchover to the redundant supervisor engine.
This problem is resolved in Release 12.1(22)E. (CSCed61632)
• 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(22)E. (CSCed47753)
• A reload might occur when an exception is generated as the result of adding a policy. This problem
is resolved in Release 12.1(22)E. (CSCed46684)
• Gigabit Ethernet negotiation does not work. This problem is resolved in Release 12.1(22)E.
(CSCed19431)
• When a Border Gateway Protocol (BGP) process propagates routes that are learned from an interior
Border Gateway Protocol (iBGP) peer to an external BGP (eBGP) peer, the eBGP peer should see
these routes with the next-hop address of the originator’s address, but the eBGP peer incorrectly sees
the routes with the next-hop address of the router that propagates the routes instead of the router that
originates the routes. This problem is resolved in Release 12.1(22)E. (CSCed15277)
• To avoid dropping into ROMMON, do not insert a WS-X6816-GBIC that does not have a DFC
installed. This problem is resolved in Release 12.1(22)E. (CSCed14506)
• Malfunctioning PIM, MLSM, or mwheel processes might cause “CPUHOG” and “WATCHDOG”
messages and reloads. This problem is resolved in Release 12.1(22)E. (CSCed12393)
• Weighted Fair Queuing WFQ over Frame Relay runs like first-in-first-out (FIFO). This problem is
resolved in Release 12.1(22)E. (CSCed09383)
• 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(22)E. (CSCed07253)
• Occasionally, the nvram:/startup-config file cannot be read. This problem is resolved in
Release 12.1(22)E. (CSCed06462)
• 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(22)E. (CSCed05843)
