Configuring IP Multicast Protocols

This display shows the following information.

 

This Field...

Displays...

 

 

 

 

 

 

(<source>, <group>)

The comma-separated values in parentheses is a source-group pair.

 

 

 

The <source> is the PIM source for the multicast <group>. For

 

 

 

example, the following entry means source 209.157.24.162 for group

 

 

 

239.255.162.1: (209.157.24.162,239.255.162.1)

 

 

 

If the <source> value is * (asterisk), this cache entry uses the RP

 

 

 

path. The * value means “all sources”.

 

 

 

If the <source> is a specific source address, this cache entry uses the

 

 

 

SPT path.

 

 

 

 

 

 

RP<ip-addr>

Indicates the RP for the group for this cache entry.

 

 

 

Note: The RP address appears only if the RPT flag is set to 1 and the

 

 

 

SPT flag is set to 0 (see below).

 

 

 

 

 

 

forward port

The port through which the routing switch reaches the source.

 

 

 

 

 

 

Count

The number of packets forwarded using this cache entry.

 

 

 

 

 

 

Sparse Mode

Indicates whether the cache entry is for regular PIM (dense mode) or

 

 

 

PIM Sparse. This flag can have one of the following values:

 

 

 

• 0 – The entry is not for PIM Sparse (and is therefore for the dense

 

 

 

mode of PIM).

 

 

 

• 1– The entry is for PIM Sparse.

 

 

 

 

 

 

RPT

Indicates whether the cache entry uses the RP path or the SPT path.

 

 

 

The RPT flag can have one of the following values:

 

 

 

• 0 – The SPT path is used instead of the RP path.

 

 

 

• 1– The RP path is used instead of the SPT path.

 

 

 

Note: The values of the RP and SPT flags are always opposite (one

 

 

 

is set to 0 and the other is set to 1).

 

 

 

 

 

 

SPT

Indicates whether the cache entry uses the RP path or the SPT path.

 

 

 

The SP flag can have one of the following values:

 

 

 

• 0 – The RP path is used instead of the SPT path.

 

 

 

• 1– The SPT path is used instead of the RP path.

 

 

 

Note: The values of the RP and SPT flags are always opposite (one

 

 

 

is set to 0 and the other is set to 1).

 

 

 

 

 

 

Register Suppress

Indicates whether the Register Suppress timer is running. This field

 

 

 

can have one of the following values:

 

 

 

• 0 – The timer is not running.

 

 

 

• 1 – The timer is running.

 

 

 

 

 

 

member ports

Indicates the routing switch physical ports to which the receivers for

 

 

 

the source and group are attached. The receivers can be directly

 

 

 

attached or indirectly attached through other PIM Sparse routers.

 

 

 

 

 

 

virtual ports

Indicates the virtual interfaces to which the receivers for the source

 

 

 

and group are attached. The receivers can be directly attached or

 

 

 

indirectly attached through other PIM Sparse routers.
