Brocade# debug pimsm-snoop show
pimsm-snoop debug-enable-any = 1
debug pimsm-snoop is enabled
debug pimsm-snoop physical_port e4/48 is enabled
debug pimsm-snoop error is enabled

debug pimsm-snoop source
Syntax: [no] debug pimsm-snoop source source_address
This command displays the PIM-SM snooping related debug information for the specified source
address. Command output resembles the following example.
Brocade# debug pimsm-snoop source 10.27.27.5
Brocade# pim_snoop join (10.27.27.5 228.228.0.1), from e1/1/12
pim_snoop join (10.27.27.5 228.228.0.2), from e1/1/12
pim_snoop join (10.27.27.5 228.228.0.3), from e1/1/12
PIM from 10.27.27.2, vlan 275, port 1/1/12: Src=10.27.27.5 with 0 JOIN with 0
PRUNE
pim_snoop prune 1/1/12 from (10.27.27.5, 228.228.0.1), pim_snoop prune
1/1/12 from (10.27.27.5, 228.228.0.2), pim_snoop prune 1/1/12 from
(10.27.27.5, 228.228.0.3), PIM from 10.27.27.2, vlan 275, port 1/1/12:

MLD snooping debug commands
Multicast Listener Discovery (MLD) discovers multicast listeners, or nodes that want to receive
multicast packets on directly attached links. MLDv2 supports source filtering, the ability of a node
to send reports on traffic that is from a specific address source or from all multicast addresses
except the specified address sources. The information is then provided to the source-specific
multicast (SSM) routing protocols such as PIM-SSM.
The following commands display information related to the MLD snoop debugging.
debug mld-snoop add-del-oif all
Syntax: [no] debug mld-snoop add-del-oif all
This command displays information about the addition or deletion of all the OIFs that are MLD
snooping-enabled.
Brocade# debug mld-snoop add-del-oif all
mldsnoop add-del-oif all enabled
