Description This command configures the mulitcast CAC policy name.
Parameters policy-name — The multicast CAC policy name. Allowed values are any string up to 32 characters
long composed of printable, 7-bit ASCII characters. If the string contains special characters (#, $,
spaces, etc.), the entire string must be enclosed within double quotes.

Description This command configure the bandwidth assigned for interface's multicast CAC policy traffic. When
disabled (no unconstrained-bw), there is no constraint on bandwidth allocated at the interface. When
enabled and if a multicast CAC policy is assigned on the interface, then no group (channel) from that
policy is allowed on the interface.
Description This command configures the bandwidth for the interface's multicast CAC policy traffic. When
disabled (no unconstrained-bw) there will be no checking of bandwidth constraints on the interface
level. When enabled and a policy is defined, enforcement is performed. The allocated bandwidth for
optional channels should not exceed the unconstrained-bw minus the mandatory-bw and the
mandatory channels have to stay below the specified value for the mandatory-bw. After this
interface check, the bundle checks are performed.
Parameters bandwidth — The bandwidth assigned for interface's MCAC policy traffic, in kilo-bits per second
(kbps).
Values
1— 2147483647
mandatory-bw mandatory-bw — Specifies the bandwidth pre-reserved for all the mandatory
channels on a given interface in kilo-bits per second (kbps).
If the bandwidth value is 0, no mandatory channels are allowed. If the value of bandwidth is '-1',
then all mandatory and optional channels are allowed.
If the value of mandatory-bw is equal to the value of bandwidth, then all the unconstrained
bandwidth on a given interface is allocated to mandatory channels configured through multicast
CAC policy on that interface and no optional groups (channels) are allowed.
The value of mandatory-bw should always be less than or equal to that of bandwidth, An attempt
to set the value of mandatory-bw greater than that of bandwidth, will result in inconsistent value
error.
