[e-nsp] Rate-limit Ingress & Egress

[Changjie]

Hello Jake,

Here is from my lab testing sometime ago, I believe its on EW 7.7:

!-- Topology
[Tester Port 1/2] --- [1] Summit400 [2] --- [Tester Port 1/3]
10.0.0.1/30                                 10.0.0.2/30
350Mbps of traffic --->
(One directional)


- The above is consistently pumping throughout the test

<-- After I configured the followings:
# create access-mask port-based-am ports
# create rate-limit ingress-100m-port-1 port-based-am port 1 permit limit
100 exceed-action drop

The above is based on Ingress policer on port 1:
* Summit400-48t:27 # show rate-limit ingress-100m-port-1
Rate-Limit "ingress-100m-port-1"
       Access-mask:    "port-based-am"
       MAC:
       IP/mask:L4port: dest-ip=none/--:---- source-ip=none/--:----
       Layer 2:
       Layer 3/4:
       Egress Port:
       Ingress Ports:   1
       In Profile:     permit
       Rate Limit:     100 Mbps
       Out Profile:    drop


I havent gotten the chance to try egress.
You can also refer to command reference on 'create rate-limit' which is only
available in "e" series
Do note:
Summit 400           => "e" series
BD6808, Summit 5i => "i" series

Hope the above helps.

Cheers!
