Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
With no cable connected, an OSM-4GE-WAN-GBIC module incorrectly display status and protocol
as “up.” This problem is resolved in Release 12.1(13)E4. (CSCdz45070)
Resolved OSM Caveats in Release 12.1(13)E3
Occasionally, the “OIRTWICE” error message displays during OIR of two OSMs. This may
happened at boot up or during an RPR+ switchover. This problem is resolved in Release 12.1(13)E3.
(CSCdz01886)
An initial reload of the system may cause the OC-48 DPT/POS modules to reload continuously. This
problem is resolved in Release 12.1(13)E3. (CSCdy62569)
If there is no traffic on PVCs configured for BRE on an OC-12 ATM OSM, the counters for the ATM
subinterface will display incorrect information. This problem is resolved in Release 12.1(13)E3.
(CSCdy87889)
An OC-48 POS OSM may reset after a system reload. This problem is resolved in
Release 12.1(13)E3. (CSCdz03157)
After an RPR+ switchover, the OSM-4GE-WAN-GBIC ports fails to forward traffic.
Workaround: Enter a shutdown command followed by a no shutdown command. This problem is
resolved in Release 12.1(13)E3. (CSCdz39010)
On an OSM-16OC3-POS-MM module with high-speed traffic running on the ports, the line protocol
on the ports may occasionally go down after a supervisor engine RPR+ switchover. This problem is
resolved in Release 12.1(13)E3. (CSCdz13392)
If you configure OAM on a multipoint PVC on an OC-12 ATM OSM, the line protocol on the
interface will go up and down sporadically. This problem is resolved in Release 12.1(13)E3.
(CSCdz20650)
Resolved OSM Caveats in Release 12.1(13)E1
Because subinterfaces on the OSM-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(13)E1. (CSCdx38389)
IGMP snooping does not function over an EoMPLS connection if the connection is made over a POS
interface. This problem is resolved in Release 12.1(13)E1. (CSCdw73064)
If you use a subinterface on the 4-port Gigabit Ethernet WAN OSM to connect a Cisco 7600 series
router or Catalyst 6500 series switch Provider Edge to an MPLS core, the VLAN ID on the
subinterface cannot be the same as the VLAN ID of the VLAN interface where the EoMPLS route
is configured. This problem is resolved in Release 12.1(13)E1. (CSCdv79130, CSCdw61392)
If multiple OC-12-ATM OSMs with large configurations are installed in a system, you may not be
able to boot the OC-12-ATM OSMs simultaneously. This problem is resolved in Release 12.1(13)E1.
(CSCdy21621, CSCdy14468)
In a system with a channelized DS3 OSM installed and more than 10,000 IP routes present, the
following error message may be displayed for the channelized DS3 OSM:
FIB-3-FIBDISABLE: Fatal error, slot/cpu 4/0: no memory
This problem is resolved in Release 12.1(13)E1. (CSCdy19072, CSCdy40632)
In a system with a large number of Frame Relay subinterfaces configured, some subinterfaces will
not be functional after the system switches over from the active route processor to the redundant
route processor. This problem is resolved in Release 12.1(13)E1. (CSCdy26531)
