Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
• Because of a lack of IPC buffer space, a system with a Supervisor Engine1 and an MSFC2 running
Release 12.1(8b)E8 may reload when InterCard Communication (ICC) messages are waiting in the
queue. Before the system reloads, messages similar to these may appear:
%ICC-SP-5-WATERMARK:5988 pkts for class L3-MGR are waiting to be processed
%IPC-SP-3-NOBUFF:The main IPC message header cache has emptied
This problem is resolved in Release 12.1(11b)E2. (CSCdw53279, CSCdx05096)
• A system with a Supervisor Engine 1 and either an MFCS1 or MSFC2 may reload when the number
of buffers available is exhausted. This problem is resolved in Release 12.1(11b)E2. (CSCdx16248)
Resolved Caveats in Release 12.1(11b)E1
• With Supervisor Engine 2, IOS Server Load Balancing (SLB) does not forward fragmented packets
in accordance with the RADIUS Load Balancing framed-IP sticky database. This problem only
affects trailer-fragmented IP packets sourced by a subscriber whose IP address is in the framed-IP
sticky database when the ip slb route command is entered. This problem is resolved in
Release 12.1(11b)E1. (CSCdw86527)
• The IOS Server Load Balancing ip slb natpool command is not accepted upon reload if
configuration of the initial allocation or maximum allocation of client NAT address entities is
configured. This allocation is configured using the entries keyword.
Workaround: Enter the ip slb natpool command without the entries keyword. This problem is
resolved in Release 12.1(11b)E1. (CSCdw88469)
• With a Supervisor Engine 2, IOS Firewall Load Balancing (FWLB) does not install hardware
shortcuts in the firewall-to-host direction. Functionality works correctly, but performance is
affected. This problem is resolved in Release 12.1(11b)E1. (CSCdx01014)
• Supervisor Engine 2 might incorrectly show that an ACL entry has been made in the TCAM, when
actually there are insufficient TCAM resources available, as indicated by TCAM
entry-capacity-exceeded messages. This problem is resolved in Release 12.1(11b)E1.
(CSCdw91641)
• With IP or IPX ACLs configured on an interface, any incoming IPX packets with source and
destination network numbers set to zero might get dropped on that interface. This problem is
resolved in Release 12.1(11b)E1. (CSCdw76549)
• The mls aging fast command has no effect. This problem is resolved in Release 12.1(11b)E1.
(CSCdw66953)
• MAC address entries on DFCs do not age out. This problem is resolved in Release 12.1(11b)E1.
(CSCdw76397)
• If a port is configured as a Layer 2 port with the switchport command when the switch boots and is
later configured as a Layer 3 port by entering the no switchport command, the show ip interface
brief command displays the port as having an invalid configuration until you enter an ip address
command or a no ip address command. If the invalid configuration is not cleared before the switch
is rebooted, the interface is returned to defaults. This problem is resolved in Release 12.1(11b)E1.
(CSCdw77676)
• When configured with the diagnostic level complete command and with complex VACLs, a switch
might fail the diagnostics because the VACLs interfere with the diagnostics. This problem is
resolved in Release 12.1(11b)E1. (CSCdw81297)
