Controlling the maximum outgoing VLAN bandwidth

When configuring a VLAN interface, you can use the outbandwidth option to set the maximum outgoing bandwidth that traffic over the VLAN interface can use.

config system interface

edit "vlan11-vdom1"

set vdom "vdom1"

...

set outbandwidth <max-bandwidth>

...

set interface "npu0_vlink0"

set vlanid 11

end

<max-bandwidth> set the maximum outgoing bandwidth in kbps for the VLAN interface. The default is 0 which means no maximum. The range is 0 to 100000000 kbps.

Controlling outgoing VLAN bandwidth can be useful for limiting the amount of bandwidth used by a VLAN interface added to an NPU accelerated VDOM link interface. The NP7 virtual egress processor (VEP) controls the amount of bandwidth that can be used by NPU accelerated VDOM link interfaces. If you are experiencing VEP over subscription issues due to the amount of traffic passing through VLAN interfaces added to NPU accelerated VDOM link interfaces, you can use the VLAN interface outbandwidth option to control the amount of traffic that can pass through the VLAN interface. For more information about VEP, see Bandwidth control for NPU accelerated VDOM link interfaces.
