Caveats
Resolved OSM Caveats in Release 12.1(20)E6
None.
Resolved OSM Caveats in Release 12.1(20)E3
• OSM ATM interfaces do not support the SNMP lowerLayerDown value defined in RFC 2863. This
problem is resolved in Release 12.1(20)E6. (CSCee56269)
Resolved OSM Caveats in Release 12.1(20)E2
• 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(20)E2. (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(20)E2.
(CSCec67501)
• Directed broadcasts to a destination network that is part of an MPLS VPN fail.This problem is
resolved in Release 12.1(20)E2. (CSCec75499)
• Parallel Express Forwarding (PXF) CEF load balancing does not work. This problem is resolved in
Release 12.1(20)E2. (CSCdu47678)
• Distributed CEF switching does not work for multilink interface egress traffic. This problem is
resolved in Release 12.1(20)E2. (CSCec55650)
• 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(20)E2. (CSCed07367)
• The 64-bit counter on the OSM-2+4GE-WAN+ main interface shows an incorrect value of zero. This
problem is resolved in Release 12.1(20)E2. (CSCec34010)
• An OC-12 POS OSM might reset as a result of memory corruption. This problem is resolved in
Release 12.1(20)E2. (CSCec59550)
Resolved OSM Caveats in Release 12.1(20)E
• Exported NetFlow counts are less than the actual value when parallel express forwarding (PXF) is
enabled. This problem is resolved in Release 12.1(20)E. (CSCea45873)
• On OSMs, Cisco IOS software disables some GBICs when the software incorrectly reports that the
GBIC has a faulty EEPROM instead of type 25 or type 29 media (“unknown media type”). This
problem is resolved in Release 12.1(20)E. (CSCeb86171)
• Because subinterfaces on the OSM-2+4GE-WAN+ module cannot share HSRP group numbers, the
4-port Gigabit Ethernet WAN module supports only 16 HSRP groups per Gigabit Ethernet WAN
port. This problem is resolved in Release 12.1(20)E. (CSCeb11624)
• When TTL propagation has been turned off by entering the tag-switching ip propagate-ttl
command, MPLS TTLs are still copied to IP packets. This problem is resolved in Release 12.1(20)E.
(CSCdy47341)
• A Catalyst 6509 with an OSM module installed experiences a drop in output on the Gigabit Ethernet
port when you connect another device to that port. This problem is resolved in Release 12.1(20)E.
(CSCdz62748)
• An ATM OSM module does not route packets between bridged RFC 1483 PVCs that are configured
in different VLANs. This problem is resolved in Release 12.1(20)E. (CSCea84940)
