• Configuring the Switch as a Statically Connected Member, page 1-44 (optional)
Default IGMP Configuration
Configuring the Switch as a Member of a Group
You can configure the switch as a member of a multicast group and discover multicast reachability in a
network. If all the multicast-capable routers and multilayer switches that you administer are members of
a multicast group, pinging that group causes all these devices to respond. The devices respond to ICMP
echo-request packets addressed to a group of which they are members. Another example is the multicast
trace-route tools provided in the software.
Caution Performing this procedure might impact the CPU performance because the CPU will receive all data
traffic for the group address.
