OL-2310-11
Caveats
• In a Multiprotocol Label Switching (MPLS) Virtual Private Network (VPN) environment, incorrect
tags might be imposed after a route flaps. This problem is resolved in Release 12.1(26)E.
(CSCec31162)
• Changing the MTU size on a port might not change the MPLS MTU size. This problem is resolved
in Release 12.1(26)E. (CSCed17226, CSCed33822)
• With OSM serial interfaces configured, you might see these messages:
%SYS-2-GETBUF: Bad getbuffer, bytes= 65535
-Process= "<interrupt level>", ipl= 1
-Traceback= 4021F160 402E3BCC 40E9CA28 40E90E68 402D545C 40294A0C
This problem is resolved in Release 12.1(26)E. (CSCed82736)
• If you enter the encapsulation dot1q vlan_id command on an OSM Gigabit Ethernet WAN port with
the VLAN ID of an internal VLAN, the port does not forward traffic. This problem is resolved in
Release 12.1(26)E. (CSCef08790)
• 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(26)E.
(CSCef32629)
• 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(26)E. (CSCef35398)
• When any interface on an OSM-12CT3/T1 goes down, traffic to a directly connected router might
experience high latency. This problem is resolved in Release 12.1(26)E. (CSCef47466)
• When deleting and re-adding channels on an OSM-12CT3/T1 T1 interface, the SNMP ifindex
disappears. This problem is resolved in Release 12.1(26)E. (CSCef70298)
• When configured as an 802.1q trunk port, the Layer 2 LAN ports on OSMs do not allow for the
802.1q tag when counting packets as giants. This problem is resolved in Release 12.1(26)E.
