Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
• 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(22)E3. (CSCee35867)
• If you have an input service policy that is configured only to police attached to an OSM interface
and you do not have an output service policy attached to the OSM interface and you OIR another
module, the OSM might reset. This problem is resolved in Release 12.1(22)E3. (CSCee42074)
• Traffic loss might occur on OSMs when there are frequent OIRs. This problem is resolved in
Release 12.1(22)E3. (CSCee54642)
• OSM ATM interfaces do not support the SNMP lowerLayerDown value defined in RFC 2863. This
problem is resolved in Release 12.1(22)E3. (CSCee56269)
Resolved OSM Caveats in Release 12.1(22)E2
• An OSM-12CT3/T1 module with an E1 channel group configured is powered down. This problem
is resolved in Release 12.1(22)E2. (CSCee42278)
• An OSM might be reset following an online insertion and removal (OIR) of a Switch Fabric Module
(SFM) or during periods of heavy traffic. This problem is resolved in Release 12.1(22)E2.
(CSCin37112)
• A reload might occur if you enter a show controllers sonet command with an invalid number for a
T1 interface on a OSM-1CHOC12/T1-SI or OSM-12CT3/T1 module. This problem is resolved in
Release 12.1(22)E2. (CSCee50911)
• OSM-1CHOC12 modules become unresponsive and are power cycled. This problem is resolved in
Release 12.1(22)E2. (CSCee45508)
Resolved OSM Caveats in Release 12.1(22)E1
None.
Resolved OSM Caveats in Release 12.1(22)E
• The serial interface input and output counters for an OSM always show 0 when you enter the show
interfaces serial command. This problem is resolved in Release 12.1(22)E. (CSCed07367)
• An E3 serial interface on an OSM-1CHOC12/T3-SI module might be inactive after you enter
shutdown and no shutdown commands. This problem is resolved in Release 12.1(22)E.
(CSCed92724)
• OSM-4GE-WAN interfaces remain in the “up/up” state when the other end of the link is inactive.
This problem is resolved in Release 12.1(22)E. (CSCec79460)
• If you delete and recreate Frame Relay subinterfaces in random order on OSM POS interfaces, some
traffic might be sent to the wrong subinterface. This problem is resolved in Release 12.1(22)E.
(CSCec67501)
• When EoMPLS virtual circuits (VCs) are loadbalanced across an OSM-2+4GE-WAN+ physical
interface and a subinterface, the OSM reloads if you remove a service policy from the physical
interface. This problem is resolved in Release 12.1(22)E. (CSCec65147)
• VRF ping packets are counted by the input counters for OSM physical interfaces, but not by the
subinterface input counters. This problem is resolved in Release 12.1(22)E. (CSCea74537)
• OSM MLPPP interfaces do not support payload IPv4 protocol id compression in hardware. This
problem is resolved in Release 12.1(22)E. (CSCed76259)
• An OC-12 POS OSM might reset as a result of memory corruption. This problem is resolved in
Release 12.1(22)E. (CSCec59550)
