input / output policer & input / output shaper Questions


I have read some post related to Policer but all are refering to a port configurations.

Is policer input / output supported per vlan or bridge interface?

ej:

swp1 -- > trunk

swp1.10 input/ouput 10Mbps
swp1.20 input/ouput 20Mbps
swp1.30 input/ouput 30Mbps

Any roadmap for shaping-rate input/output support per vlan?

Thanks

Yes just apply it to the SVI, e.g. under the vlan interface if using NCLU, it will work
Hi sean,

we will not use SVI the scenario is:

PC <> vlan 10 <> swp1.10 <> vxlan <> evpn <> remote site <> evpn <> vxlan <> swp1.10 vlan 10 <> PC

Pure L2 circuit end to end.

Hey Jorge,

Sorry for the slow response, wanted to check with engineering. You don't need an IP address on the VLAN interface (Switch VLAN Interface) to use a policer. It will work and perform expected functionality. In your case it looks like you are using sub-interfaces with traditional bridge. You would just put the policer on the bridge interface which acts as the SVI. I imagine so this is so you can re-use VLANs on ports but not be on the same broadcast domain? That is fine, just making sure you are aware of the VLAN-aware bridge which is simpler to configure if that is not a requirement.
