unicast-suppression (network enhanced profile view)

Function

The unicast-suppression command configures unknown unicast traffic suppression in a network enhanced profile.

The undo unicast-suppression command cancels unknown unicast traffic suppression in a network enhanced profile.

By default, unknown unicast traffic suppression is not configured in a network enhanced profile.

This command can only be executed on a parent switch.

Format

unicast-suppression packets packets-per-second

undo unicast-suppression

Parameters

Parameter	Description	Value
packets packets-per-second	Specifies the packet rate of an interface.	The value is an integer that ranges from 0 to 14881000, in packets per second (PPS). If the configured packet rate on the parent switch is larger than the maximum value on the AS port, the maximum value takes effect on the AS port.

Usage Guidelines

After creating a network enhanced profile, you can configure unknown unicast traffic suppression in the profile. After the profile is bound to an AS port, unknown unicast traffic suppression is automatically configured on the port. The following configuration is generated on the AS port:

#
 unicast-suppression packets packets-per-second
#

To prevent broadcast storms, you can run the unicast-suppression command to configure the maximum number of unknown unicast packets that can pass through a port. When the unknown unicast traffic rate reaches the rate limit, the system discards excess unknown unicast packets to control the traffic volume within a proper range.
