Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
• A reload might occur if you enter the interface loopback interface_number interface configuration
command and the value of the interface_number argument is a 9-digit number that starts with 10.
This problem is resolved in Release 12.1(22)E. (CSCec03907)
• Because the WCCP service group list is scanned in the order in which service groups are created,
rather than by priority, with multiple dynamic WCCP services defined, traffic that matches the
selection criteria for more than one service group is not redirected to the service group with the
highest priority. This problem is resolved in Release 12.1(22)E. (CSCec55429)
• When Automatic Protection Switching (APS) is not configured on a POS interface, ignore an
incrementing “COAPS” counter. This problem is resolved in Release 12.1(22)E. (CSCec89414)
• NetFlow Data Export (NDE) does not support multicast traffic, but NDE might export some
multicast data. This problem is resolved in Release 12.1(22)E. (CSCec37069)
• With Web Cache Communication Protocol (WCCP) configured and the cache farm formed
successfully, packet redirection to a cache might not occur. This problem is resolved in
Release 12.1(22)E. (CSCuk47528)
• HSRP packets are sent with the IP TTL field set to 2 instead of 1. This does not affect HSRP
operation because HSRP packets are sent to a Layer 2 multicast address. This problem is resolved
in Release 12.1(22)E. (CSCuk31498)
• A reload might occur after you enter the shutdown and no shutdown interface configuration
commands multiple times on different interfaces. This problem is resolved in Release 12.1(22)E.
(CSCed55567)
• When the HSRP MIB is polled and there are HSRP groups configured on subinterfaces, an error
such as “OID not increasing” might occur on the device that is polling the router. In some cases, a
CPUHOG traceback may occur on a router when the HSRP MIB is polled, especially when a lot of
interfaces are configured but HSRP is not configured at all. This problem is resolved in
Release 12.1(22)E. (CSCed52163)
• With Multiprotocol Label Switching (MPLS) configured, after accessing a freed Label Information
Base (LIB) entry, this message might be displayed:
%TIB-3-LCLTAG: 10.10.10.10/10.10.10.10, tag advert; unexpected tag state=13
After the message is displayed, a reload might occur. This problem is resolved in Release 12.1(22)E.
(CSCed47409)
• When configured as a PE router, if you change the layer encapsulation of a PPP, Frame Relay, or
HDLC PE subinterface, ping traffic to a CE router might fail. This problem is resolved in
Release 12.1(22)E. (CSCed13350)
• A switched virtual circuit (SVC) might not transition to the established state. This situation might
cause ping failures. This problem is resolved in Release 12.1(22)E. (CSCec80061)
• With an ATA flash device, you might see this message:
PCMCIAFS-5-DIBERR: PCMCIA disk 0 is formatted from a different router or PC. A format
in this router is required before an image can be booted from this device
This problem is resolved in Release 12.1(22)E. (CSCec69091)
• You might see high CPU utilization if you enter the logging synchronous command for line con 0.
This problem is resolved in Release 12.1(22)E. (CSCdy01705)
• When a Layer 3 VLAN interface is configured as an OSPF nonbroadcast network and a polling
interval is configured for every OSPF neighbor, unnecessary ARPs are sent. This problem is
resolved in Release 12.1(22)E. (CSCed26217)
