max-mcache

Configures the maximum size of the multicast cache.

Syntax

max-mcache num

no max-mcache

Command Default

By default, the size of the multicast cache is 32768 entries for IPv4 and 4096 entries for IPv6.

Parameters

num: Specifies the number of entries in the multicast cache. Valid values range from 1 through 32768 for IPv4 and from 1 through 4096 for IPv6.

Modes

Router PIM configuration mode

Usage Guidelines

If the max-mcache is changed to a value that is less than the current max-mcache value, the existing cache routes are not automatically deleted. The cache routes are deleted when new routes are added.

The no max-mcache form of the command restores the default size of the maximum multicast cache.

Examples

The following example changes the multicast cache to 500 entries for IPv4.

device(config)# router pim
device(config-pim-router)# max-mcache 500

The following example changes the multicast cache to 500 entries for IPv6.

device(config)# ipv6 router pim
device(config-ipv6-router-pim-vrf-default-vrf)# max-mcache 500
