Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
• When an HSRP group is configured on a OSM-4GE-WAN subinterface and MPLS VPN is
configured on the same subinterface, packet duplication might occur. This problem is resolved in
Release 12.1(13)E5. (CSCea21791)
• The OSM-4GE-WAN-GBIC module returns an incorrect port type value in CiscoView. This problem
is resolved in Release 12.1(13)E5. (CSCea28575)
• The interface Link Up/Down SNMP trap is not generated for subinterfaces on the
OSM-4GE-WAN-GBIC module after you enter a shutdown command followed by a no shutdown
command on the subinterface or main interface. This problem is resolved in Release 12.1(13)E5.
(CSCea42741)
• On ATM and POS OSM modules when the system comes up, the portType is displayed as “other”
if no GBIC is present in the Gigabit Ethernet ports. On the Gigabit Ethernet WAN OSMs, when a
GBIC is removed, the portType displays “other.” This problem is resolved in Release 12.1(13)E5.
(CSCin37330)
• Packets to an unknown MAC address that exists in the same subnet as a GE-WAN VPN routing and
forwarding (VRF) subinterface are incorrectly accepted by the GE-WAN subinterface and then
routed back to the VLAN. If there are two GE-WAN VRF subinterfaces configured for the same
VLAN for redundancy, packets are forwarded back and forth between the GE-WAN subinterfaces
until the TTL timer expires. This may cause problems for applications in the subnet and on the hosts
involved. This problem is resolved in Release 12.1(13)E5. (CSCea45053)
• The OSM-12CT3/T1 and OSM-CHOC12/T1-SI modules do not support wire-rate traffic on serial
interfaces. This problem is resolved in Release 12.1(13)E5. (CSCdz46704)
• Input-shaping policies on OSMs shape at a lower rate than the configured rate. This problem is
resolved in Release 12.1(13)E5. (CSCdy15369)
• On an OSM-2+4GE-WAN+ module, if you apply a nonhierarchical service policy to the physical
port 2 or port 4 interface when port 1 or port 3 is shutdown, the service-policy application fails
without notice. This problem is resolved in Release 12.1(13)E5. (CSCdz57493)
• The OSM-2+4GE-WAN+ module does not support WS-G5483 GBICs. This problem is resolved in
Release 12.1(13)E5. (CSCdz88585)
• On a GE-WAN port configured as a Layer 3 trunk, if you change the encapsulation from ISL to
IEEE 802.1Q or from IEEE 802.1Q to ISL, all trunk traffic is routed in software by the MSFC2. This
problem is resolved in Release 12.1(13)E5. (CSCdz89162)
Resolved OSM Caveats in Release 12.1(13)E4
• Automatic Protection Switching (APS) switchover on OSM-1CHOC12/T1-SI modules configured
with multilink point-to-point protocol (MLPPP) might cause a reload. This problem is resolved in
Release 12.1(13)E4. (CSCdz39636)
• After Automatic Protection Switching (APS) switchover on OSM-1CHOC12/T1-SI modules, 64
Kbps serial interfaces might flap. This problem is resolved in Release 12.1(13)E4. (CSCdz39636)
• If you configure QSAAL or ILMI virtual circuits (VCs) on a 2-port OC-12 ATM OSM interface, you
will not be able to configure AAL5SNAP VCs on that same interface. If you try to do this, the
following message will display:
00:12:38:%CWANLC_ATM-4-MISMATCH_VCENCAP:ATM9/2:Cannot mix aal5snap & mux
VCs in same swidb
This problem is resolved in Release 12.1(13)E4. (CSCdz62725)
• The arp ip_address mac_address {srp-a | srp-b} command does not work on OSM-2OC48/1DPT
modules. This problem is resolved in Release 12.1(13)E4. (CSCdw13108)
