Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
• After you enter the snmp-server enable traps sonet command, the no snmp-server enable traps
sonet command fails. If you enter the show run command, you will see that the traps are still
enabled. This problem is resolved in Release 12.1(27b)E. (CSCeg41564)
• In RPR+ mode, when the standby supervisor engine is reset, an SNMP ModuleDown trap indicates
that a specific module has been powered down or reloaded. The moduleType in this trap is 1 (other)
instead of the correct value. This problem is resolved in Release 12.1(27b)E. (CSCeg81646)
• When you enter the show mac command for GBIC ports that are showing a notconnect status, you
will see that the Out-Discard and Rcv-Octet counters continue to increment. This problem is
resolved in Release 12.1(27b)E. (CSCeg64770)
• When you enter the show controllers pos slot-number pm time-interval command SONET statistics
for POS interfaces are not displayed in the correct order in the output . The order of display should
be the most recent first. This problem is resolved in Release 12.1(27b)E. (CSCea70822)
• The system might not allow incoming Telnet sessions. This problem occurs in a low-memory
situation. This problem is resolved in Release 12.1(27b)E. (CSCdx39953)
• IOS Connectionless Network Service (CLNS) fast-switching is disabled on a serial E3 interface that
is configured for High-Level Data Link Control (HDLC) encapsulation. This problem is resolved in
Release 12.1(27b)E. (CSCsa45381)
• A system configured with DLSw+ Ethernet redundancy might reload when you enter the show dlsw
transparent neighbor command. This problem is resolved in Release 12.1(27b)E. (CSCsc52939)
• A system configured for Point-to-Point Protocol (PPP) Multilink might reload because of a bus
error. This problem is resolved in Release 12.1(27b)E. (CSCsa87205)
• A device might fail to start a DLSw session when the client sends an Exchange Identification (XID)
to SSAP and DSAP populated with non-zero entries and without an ID block or number. The Logical
Link Control (LLC) test frames indicate that the device never sees or acknowledges this XID frame
to start the session. This problem is resolved in Release 12.1(27b)E. (CSCdy59779)
• If a Supervisor Engine 2 is configured with a Layer 2 nondistributed EtherChannel and a Layer 3
DEC, traffic ingressing on any port and egressing on the Layer 2 non-DEC, floods within the VLAN
that contains the destination MAC address. This situation occurs when the EtherChannel purging
timer expires (approximately every 21 minutes). The number of flooded packets depends on the
traffic rate and Layer 2 table size. This problem is resolved in Release 12.1(27b)E. (CSCsc54382)
• A CPUHOG message might display when the system is configured with 200 multicast groups and
processing traffic from 2000 hosts. This problem does not affect performance. This problem is
resolved in Release 12.1(27b)E. (CSCdy64412)
• The output counters in the show frame-relay pvc maplist command are not being updated for either
IP traffic or MPLS traffic. This problem is resolved in Release 12.1(27b)E. (CSCec08821)
• If OSPF is enabled on an interface, and then the configuration is changed to redistribute a connected
route on this interface with a route map, then the route may not be redistributed correctly. This
problem occurs only if the route map is used as a parameter with the redistribute command. This
problem is resolved in Release 12.1(27b)E. (CSCee81606)
• In rare circumstances, a group of four ports (1 to 4, 5 to 8, 9- to 12, or 13 to 16) on the
WS-X6516-GE-TX module may experience connectivity problems. If this problem occurs, the
following syslog messages might be seen:
%PM_SCP-SP-6-LCP_FW_ERR_INFORM: Module 4 is experiencing the following error:
Pinnacle #0 Frames with Bad Packet CRC Error (PI_CI_S_PKTCRC_ERR - 0xC7) = 110
This problem is resolved in Release 12.1(27b)E. (CSCef46923)
