Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
• The MSFC might reload after receiving OSPF link-state advertisements (LSAs) that have an illegal
mask. This problem is resolved in Release 12.1(12c)E1. (CSCdx70216)
• An extremely complex ACL configuration might cause “idbman_get_port_idb: slot out of range for
slot” messages. This problem is resolved in Release 12.1(12c)E1. (CSCdx68009)
• The TestIpFibShortcut diagnostic fails intermittently. This problem is resolved in
Release 12.1(12c)E1. (CSCdx53670)
• DFC-equipped switching modules might not initialize properly after a reload. This problem is
resolved in Release 12.1(12c)E1. (CSCdx52003)
• Heavy VPN traffic might increase MSFC CPU utilization and cause OSPF adjacencies to be lost.
This problem is resolved in Release 12.1(12c)E1. (CSCdx47514)
• You cannot configure more than 16 HSRP groups per port on subinterfaces configured on
OSM-4GE-WAN ports. This problem is resolved in Release 12.1(12c)E1. (CSCdx38389)
• Some packets might be dropped on a Fast Ethernet port that is sending traffic to a Content Switching
Module (CSM) configured to perform Network Address Translation (NAT). This problem is
resolved in Release 12.1(12c)E1. (CSCdx38234)
• IPC-SP-5-WATERMARK messages indicating that many messages are pending might be displayed
continuously. There are no messages pending; this is a cosmetic defect with the messages pending
counter. This problem is resolved in Release 12.1(12c)E1. (CSCdw74873)
• A reload might occur after IPC-5-LIMIT messages are displayed. This problem is resolved in
Release 12.1(12c)E1. (CSCdv53846)
• A VACL configured with the capture option incorrectly captures traffic that should be denied by a
Cisco IOS ACL. This problem is resolved in Release 12.1(12c)E1. (CSCdu61309)
• In a redundant configuration, after you receive LYRA-SP-2-PARITY_ERR messages, switchover to
the standby Supervisor Engine 2 did not occur. This problem is resolved in Release 12.1(12c)E1.
(CSCdx44052)
• With 7,000 NAT entries and 3 kpps of NAT traffic, MSFC CPU utilization is 100 percent. This
problem is resolved in Release 12.1(12c)E1. (CSCdx40232)
• After a reload that is caused by a fault, a crashinfo file might not exist. This problem is resolved in
Release 12.1(12c)E1. (CSCdx38379)
• If you install three or more Content Services Gateway (CSG) modules in the same chassis, a reload
occurs. This problem is resolved in Release 12.1(12c)E1. (CSCdw77156)
• Packets between fabric-enabled modules can be forwarded from one module to another using either
8-Gigabit Ethernet fabric interface or the 16-Gigabit Ethernet backplane bus.
With less than three fabric-enabled modules installed, replicated multicast packets are occasionally
sent over the fabric as well as the backplane bus, causing ports to receive twice as many packets as
were generated. This problem is resolved in Release 12.1(12c)E1. (CSCdw82490)
• To avoid unreliable operation, do not enter the do command in EXEC mode. This problem is
resolved in Release 12.1(12c)E1. (CSCdx02925)
