Syntax: show ip multicast pimsm-snooping
Use the show ip multicast cluster commands to display information about multicast snooping
activity.
In the following command, YES indicates that reports/leaves were received locally (processing native
control packets).
Brocade(config)# show ip multicast cluster group
p-:physical, ST:static, QR:querier, EX:exclude, IN:include, Y:yes, N:no
VL100 : 1 groups, 1 group-port
group p-port ST QR life mode source local
1 225.1.1.1 e5/5 no no 200 EX 0 YES
2 225.1.1.1 e5/10 no no 200 EX 0 YES
In the following command, NO indicates that reports/leaves were received remotely. In this case, a join
was received on the CCEP of the MCT peer device. Native control packets were processed by the
peer device, and then the entries were synched over MDUP to this cluster device.
Brocade(config)# show ip multicast cluster group
p-:physical, ST:static, QR:querier, EX:exclude, IN:include, Y:yes, N:no
VL100 : 1 groups, 1 group-port
group p-port ST QR life mode source local
1 225.1.1.1 e1/10 no no 200 EX 0 NO
2 225.1.1.1 e1/10 no no 200 EX 0 NO
The following command displays information about the IGMP multicast mcache. It is used to verify if
FDB is programmed when a data packet arrives.
Brocade(config-vlan-101)# show ip multicast cluster mcache
Example: (S G) cnt=: cnt is number of SW processed packets
OIF: e1/22 TR(e1/32), TR is trunk, e1/32 primary
[1,10]: [1 - has local oif, 10 - ICL due to CCEP count]
vlan 101, 1 caches. use 1 VIDX
1 (* 230.1.2.23) cnt=2
OIF: TR(e5/4) tag TR(e5/5)
age=37s up-time=37s, MCT-LOCAL , change=37s vidx=7405 (ref-cnt=1)
Note:
MCT_LOCAL - This flag will be set when source traffic arrives on the local port.
MCT_PEER - This flag will be set when source traffic arrives on the remote MCT
peer, then the mcache entry is synchronized to local MCT router through CCP..
The following command displays status about the IGMP router port.
device(config)# show ip multicast cluster vlan 100
Version=2, Intervals: Query=125, Group Age=260, Max Resp=10, Other Qr=260
VL100: cfg V3, vlan cfg passive, 1 grp, 2 (SG) cache, rtr ports,
router ports: e5/9(260) 100.100.100.1 (local:1, mct peer:0),
e5/4 has 1 groups,
This interface is non-Querier (passive)
default V3 trunk
(local:1, mct peer:0)
Syntax: show ip multicast cluster { group | mcache | vlan vlan-id }
Use the show ip multicast cluster pimsm-snooping command to display detailed information about
multicast snooping activity.
device(config)# show ip multicast cluster pimsm-snooping
Example: Port: 7/3 (age, port type, ref_count, owner flag, pruned flag)
