`show ip multicast data-plane`

Displays multicast Internet Group Management Protocol (IGMP) data-plane information.

Syntax

show ip multicast
                  					data-plane

{mcache | mcache-count | settings | vlan vlan-id }

Parameters

mcache: Specifies the data-plane mcache.
mcache-count: Specifies ithe data-plane mcache count.
settings: Specifies the data-plane IGMP snooping settings.
vlan vlan-id: Specifies a VLAN.

Modes

User EXEC mode

The show ip multicast data-plane command displays the following information:

Output Field	Description
in-HW:	Indicates if traffic flow is programmed in hardware.
Aging	Indicates the time remaining (Agebit).
Perm	The static mcache.
Epoch	Indicates the number of times the mcache table reconciled with the Active-CP.
Total Number of v4 DP Mcache Entries	Indicates the total number of data-plane mcache entries.
Insert Failure	Indicates if failure occurred.
Vlan-id	The ID of the VLAN.
snoop	Indicates if IP Multicast snooping is enabled.
pimsmsnoop	Indicates if PIM SM snooping is enabled.
use-sg	0: Use *,G-based forwarding 1: Use S,G-based forwarding
unreg-flood	Indicates if unregistered or unknown multicast flooding is enabled.
Mode	IP or MAC, based on forwarding table used for programming the mcache.
Local Slave Sync State	Name of sync channel used between CP and DP
Local	Indicates if the sync channel is on local unit (value 1) or remote unit.
repl user id	User ID.
Init	Indicates the module is initialized.
dysync type	Sync channel ID
alloc	Number of mcache pools that can be allocated.
in-use	Number of mcache pools currently in use.
avail	Number of available mcache pools.
get-fail	Memory get failed counter.
limit	Maximum entires allowed to be allocated dynamically.
get-mem	Memory allocated call counter.
size	Individual entry size.

Examples

The following example shows information for the IP multicast IGMP data-plane mcache.
