Statement introduced before Junos OS Release 7.4.
Statement introduced in Junos OS Release 9.0 for EX Series switches.
Statement introduced in Junos OS Release 11.3 for the QFX Series.
Description
Configure multicast forwarding cache properties. These properties include threshold suppression and reuse limits, the threshold at which a warning message is logged, and timeout values.
Specify a value for the threshold at which to suppress new multicast forwarding cache entries and an optional reuse value for the threshold at which the router begins to create new multicast forwarding cache entries. The range for both is from 1 through 200,000. If configured, the reuse value should be less than the suppression threshold value. The suppression value is mandatory. If you do not specify the optional reuse value, then the number of multicast forwarding cache entries is limited to the suppression value. A new entry is created as soon as the number of multicast forwarding cache entries falls below the suppression value.
You can configure the thresholds globally for the multicast forwarding cache or individually for the IPv4 and IPv6 multicast forwarding caches. Configuring the threshold statement globally for the multicast forwarding cache or including the family statement to configure the thresholds for the IPv4 and IPv6 multicast forwarding caches are mutually exclusive.
Default
By default, there are no limits on the number of multicast forwarding cache entries.
Options
family (inet | inet6)—(Optional) Apply the configured thresholds to either IPv4 or IPv6 multicast forwarding cache entries.
Default: By default, the configured thresholds are applied to both IPv4 and IPv6 multicast forwarding cache entries.
The remaining statements are explained separately.
