Configuring Egress Interface-based Rate Limiting

To control the rate of all outgoing traffic on an interface, configure egress interface-based rate limiting. When the transmit rate of packets exceeds the configured rate limit, the excess packets will be discarded.

set interface gigabit-ethernet <interface-name> rate-limiting egress kilobits <value>

set interface gigabit-ethernet <interface-name> rate-limiting egress ratio <value>

set interface gigabit-ethernet <interface-name> rate-limiting egress burst <burst-size>

NOTE:

In the same direction of the same interface, kilobits and ratio cannot be configured simultaneously.

When burst size is not configured, PICOS uses a burst size adapted according to the configured rate limiting value configured by the set interface gigabit-ethernet <interface-name> rate-limiting egress kilobits <value> or set interface gigabit-ethernet <interface-name> rate-limiting egress ratio <value> command.

Configuration Example

Set the rate limit to 8000 kbit/s on interface te-1/1/1 for the egress traffic, and use the system adapted burst size.

admin@Xorplus# set interface gigabit-ethernet te-1/1/1 rate-limiting egress kilobits 8000
admin@Xorplus# commit

You can use run show interface gigabit-ethernet command to check the configuration, where ”Interface rate limit ingress: , egress: ” and ”Interface burst limit ingress: , egress: ” indicating the configuration of interface-based rate limit and burst size.

admin@Xorplus# run show interface gigabit-ethernet te-1/1/1
