debug igmp-snoop group
Syntax: [no] debug igmp-snoop group group_address
The group_address is the address of the IGMP snoop multicast group.
This command displays the IGMP snooping multicast group information. Command output
resembles the following example.
Brocade# debug igmp-snoop group 230.1.1.1
IGMP: rcvd Report-V2(t=22)
VL100 (phy e1/1/48), igmp_size=8
debug igmp-snoop level
Syntax: [no] debug igmp-snoop level decimal
The decimal variable specifies the debugging level of IGMP snooping activity and it can take values
from 1 through 3.
This command sets the debuging level of IGMP snooping activity. Level 3 displays more information
than level 2, and level 0 displays no information. Command output resembles the following
example.
Brocade# debug igmp-snoop level 1
igmpsnoop debug level = 1
IGMP: rcvd Query(t=17) V2 g=0.0.0.0 resp=100, pkt S=10.1.15.1 to 224.0.0.1, on
VL100 (phy e3/1/6), igmp_size=8
Brocade# debug igmp-snoop level 3
igmpsnoop debug level = 3
Brocade# Add e1/1/2
