Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
• With high CPU utilization and line-rate traffic, byte counters on OC-48 interfaces might be wrong.
This problem is resolved in Release 12.1(23)E. (CSCee84887)
• OSM-2+4GE-WAN+ ports do not automatically adjust the MTU size to accommodate tagged traffic.
Ingress tagged packets destined for the MSFC are dropped if the packet size is larger than the ingress
interface MTU size. This problem is resolved in Release 12.1(23)E. (CSCee59667)
• OSM interface byte counts might be incorrect after a few hours of traffic handling. High traffic
levels on OC-48 interfaces might produce incorrect byte counts. This problem is resolved in
Release 12.1(23)E. (CSCee55056)
• Traffic loss might occur on OSMs when there are frequent OIRs. This problem is resolved in
Release 12.1(23)E. (CSCee54642)
• The interfaces on an OSM-2+4GE-WAN+ module might be reported as administratively “up/up”
when there is no GBIC installed. This problem is resolved in Release 12.1(23)E. (CSCee35867)
• The Gigabit Ethernet LAN ports on a OSM-2+4GE-WAN+ module might be reported as
administratively “up/up” when there is a GBIC installed but no cable attached. This problem is
resolved in Release 12.1(23)E. (CSCee01868)
• Occasionally, OSM-2+4GE-WAN+ module interfaces do not pass traffic after a reload or OIR. This
problem is resolved in Release 12.1(23)E. (CSCed83227)
