Brocade# debug igmp-snoop timer
Brocade# debug igmp-snoop prime-port eth 1/1/2
igmp timer, VL130(e1/1/2) change V1 client age out
igmp timer, E401010A VL130(e1/1/2) switch back to include mode
igmp timer, E4010109 VL130(e1/1/2) switch back to include mode
igmp timer, E4010108 VL130(e1/1/2) switch back to include mode
debug igmp-snoop vlan
Syntax: [no] debug igmp-snoop vlan vlan_id
This command displays the IGMP snooping related debug information for the specified VLAN ID.
Command output resembles the following example.
Brocade# debug igmp-snoop vlan 100
igmpsnoop monitor vlan 100
IGMP: rcvd Report-V2(t=22) g=230.1.1.110 resp=0, pkt S=10.85.1.3 to 230.1.1.110,
on VL100 (phy e1/1/48), igmp_size=8
IGMP: rcvd Report-V2(t=22) g=230.1.2.52 resp=0, pkt S=10.85.1.3 to 230.1.2.52, on
VL100 (phy e1/1/48), igmp_size=8
IGMP: rcvd Report-V2(t=22) g=230.1.3.133 resp=0, pkt S=10.85.1.3 to 230.1.3.133,
on VL100 (phy e1/1/48), igmp_size=8
IGMP: rcvd Report-V2(t=22) g=230.1.2.203 resp=0, pkt S=10.85.1.3 to 230.1.2.203,
on VL100 (phy e1/1/48), igmp_size=8
IGMP: rcvd Report-V2(t=22) g=230.1.1.151 resp=0, pkt S=10.85.1.3 to 230.1.1.151,
on VL100 (phy e1/1/48), igmp_size=8
PIM debug commands
Protocol Independent Multicast (PIM) is used to simplify some of the complexity of the routing
protocol at the cost of additional overhead tied with a greater replication of forwarded multicast
packets. PIM is similar to DVMRP in that PIM builds source-routed multicast delivery trees and
employs reverse path check when forwarding the multicast packets.
debug ip pim
Syntax: [no] debug ip pim
This command activates the PIM debugging.
Brocade# debug ip pim
PIM: pim debugging is on
debug ip pim add-del-oif
Syntax: [no] debug ip pim add-del-oif
This command shows mcache activity and will work with the debug ip pim group or debug ip pim
source commands.
Brocade# show ip pim neighbors
Total number of neighbors: 4 on 4 ports
