Configuring Ingress Interface-based Rate Limiting

If you do not limit the traffic sent by users, the continuous burst of data of a large number of users will make the network more crowded. By configuring the ingress interface-based rate limiting on the interface, you can limit the traffic entering the interface to a reasonable range.

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

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

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

NOTE:

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

Tomahawk series switches (including Tomahawk, Tomahawk+, Tomahawk2 and so forth) do not support ingress interface-based rate limiting.
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 ingress kilobits <value> or set interface gigabit-ethernet <interface-name> rate-limiting ingress ratio <value> command.

`Configuration Example`

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

admin@Xorplus# set interface gigabit-ethernet te-1/1/1 rate-limiting ingress 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.
