Resolved OSM Caveats in Release 12.1(12c)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(12c)E1. (CSCdx38389)
• In a configuration where global virtual routing and forwarding instance (VRF) routes are configured
on a 4-port Gigabit Ethernet WAN OSM, when you ping a global IP address from a customer-edge
device within a VPN, the ping fails. This failure occurs because a VRF-forwarding Gigabit Ethernet
interface can resolve ARPs in the VRF ARP table, but it cannot be in the default ARP table. This
problem is resolved in Release 12.1(12c)E1. (CSCdw74766, CSCin04666)
• Transmission of IP packets between MPLS clouds over Generic Routing Encapsulation GRE tunnels
is not supported. This problem is resolved in Release 12.1(12c)E1. (CSCdw62753)
• PFC2-based QoS is supported on all the OSMs but has not been fully tested on the 2-port OC-12
ATM OSMs and the channelized OSMs. The PFC2 QoS CLI is not blocked for these modules, but
we do not recommend that you configure PFC2-based QoS until testing has been completed. This
problem is resolved in Release 12.1(12c)E1. (CSCdw84716)
