IP Multicast Routing Commands
Privileged EXEC Mode
clear ip dvmrp route commands
debug ip dvmrp commands
The debug ip packet command displays packets received by the switch CPU. It does not display packets
that are hardware-switched.
The debug ip mcache command affects packets received by the switch CPU. It does not display packets
that are hardware-switched.
The debug ip mpacket [detail] [access-list-number [group-name-or-address] command affects only
packets received by the switch CPU. Because most multicast packets are hardware-switched, use this
command only when you know that the route will forward the packet to the CPU.
debug ip pim atm
show ip dvmrp route commands
The show ip mcache command displays entries in the cache for those packets that are sent to the switch
CPU. Because most multicast packets are switched in hardware without CPU involvement, you can use
this command, but multicast packet information is not displayed.
The show ip mpacket commands are supported but are only useful for packets received at the switch
CPU. If the route is hardware-switched, the command has no effect because the CPU does not receive
the packet and cannot display it.
