Resolved OSM Caveats in Release 12.1(23)E2
• If you configure 802.1Q tunneling on a LAN port and 802.1Q-tunnel bridging on an
OSM-2OC12-ATM-SI+ subinterface, the OSM might reload. This problem is resolved in
Release 12.1(23)E2. (CSCef35398)
Resolved OSM Caveats in Release 12.1(23)E1
• A reload might occur if you configure Point-to-Point Protocol (PPP) and High Level Data Link
Control (HDLC) on a channelized OSM. This problem is resolved in Release 12.1(23)E1.

Resolved OSM Caveats in Release 12.1(23)E
• You might see semaphore hog messages with a large Bridging of Routed Encapsulations (BRE)
configuration. This problem is resolved in Release 12.1(23)E. (CSCef07770)
• OSM-1CHOC12/T1-SI T1 interfaces that have path coding violations (PCVs) might cause
erroneous Layer 1 errors to be displayed for other T1 interfaces. This problem is resolved in
Release 12.1(23)E. (CSCed86486)
• Traffic might be dropped if you enter the no ip cef global configuration command. This problem is
resolved in Release 12.1(23)E. (CSCin40371)
• 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(23)E.
(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(23)E. (CSCee50911)
• OSM-1CHOC12 modules become unresponsive and are power cycled. This problem is resolved in
Release 12.1(23)E. (CSCee45508)
• An OSM-12CT3/T1 module with an E1 channel group configured is powered down. This problem
is resolved in Release 12.1(23)E. (CSCee42278)
• 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(23)E. (CSCee42074)
• Multicast 127-byte UDP packets that egress from OSM-2OC12-POS interfaces have invalid
checksums. This problem is resolved in Release 12.1(23)E. (CSCec72798)
• OSM ATM interfaces do not support the SNMP lowerLayerDown value defined in RFC 2863. This
problem is resolved in Release 12.1(23)E. (CSCee56269)
• OSM ATM interfaces do not support unspecified bit rate plus (UBR+) virtual circuit (VC) class
maps, but you can apply UBR+ VC class maps to VC subinterfaces. This problem is resolved in
Release 12.1(23)E. (CSCec31381)
