Unsupported Features

If you enable IP multicast Layer 3 switching, IP accounting for Layer 3 interfaces does not report
accurate values. The show ip accounting command is not supported.

If the ingress interface of a (S,G) or (*,G) entry is null, except if the (*,G) entry is a IPv4
bidirectional PIM entry and the switch is the RP for the group.
For IPv4 bidirectional PIM entries when a DF interface or RPF interface is a tunnel.
GRE tunnel encapsulation and de-encapsulation for multicast packets is handled in software.
Supervisor Engine 32 does not support egress multicast replication and cannot detect the multicast
replication mode.
