how to limit bandwidth on an Avaya 5650 port
« on: July 17, 2013, 10:16:11 PM »
Hi

   I have a stack of 5650's
   It has a 1Gbps uplink but there are a couple of file servers that have on occasion saturated the uplink
   I would like to be able to limit the traffic on some of the ports to a preset threshold,
   something like  700 Mbps.
   
   We are planning to upgrade the uplink to 10Gbps but this will not happen for another couple months, so am looking for a temporary band-aid fix

   How can I do this on a ERS-5500 series switches?


thanks
steve

In the past I've intentionally changed the port speed (or CANA - Customizable Auto-negotiation Advertisements) to 10Mbps or 100Mbps on a few devices to prevent them from flooding the network.

It's relatively quick and easy fix for some.

The solution mentioned by @Lalitdantu involves setting up QoS bandwidth metering which is itself pretty straight forward but can be difficult to manage on a large scale.

@Lalitdantu, you can post links once you've made 10 posts, it's a restriction to keep spammer off the forum. I've bumped your post count to 10.

Thanks I will try what was referenced in the link, but the requires authentication, I will dig out my avaya credentials. What Michael suggested  would be a lot simpler but alas 100mbps is too low a constraint.
thanks

Went through this and it was a total pain.  Note, this was for significantly smaller traffic, but you can see what works and what doesn't.  Trust me when I say the 'Interface Shaper' option doesn't work under all scenarios.

From Avaya's test lab - Trying to limit Video streaming bandwidth
The top one worked for 'normal' traffic.  Neither worked for Video/Security Camera traffic.

qos if-shaper port 1/1 name "Sec Vid Port 1/1" shape-rate 512 burst-size 4
qos if-shaper port 1/2 name "Sec Vid Port 1/2" shape-rate 512 burst-size 4
qos if-shaper port 1/3 name "Sec Vid Port 1/3" shape-rate 512 burst-size 4
qos if-shaper port 1/4 name "Sec Vid Port 1/4" shape-rate 512 burst-size 4
qos if-queue-shaper port 1/1 queue 1 name "Sec MGMT 1" shape-rate 768 shape-min-rate 512
qos if-queue-shaper port 1/2 queue 1 name "Sec MGMT 2" shape-rate 768 shape-min-rate 512
qos if-queue-shaper port 1/3 queue 1 name "Sec MGMT 3" shape-rate 768 shape-min-rate 512
qos if-queue-shaper port 1/4 queue 1 name "Sec MGMT 4" shape-rate 768 shape-min-rate 512


In the end, we had to do this:

qos traffic-profile classifier name VideoTraf

qos traffic-profile set port 1,2 name VideoTraf committed-rate 768 committed-burst 4 drop-action enable track-statistics individual

hacore2(config)#show qos traffic-profile interface

Hi colleagues,

today i try to shape traffic on ERS4550.
I will try what was referenced in the link by @Lalitdantu, but is'nt working.
If i configure if-shaper, if-queue-shaper and traffic-profile was referenced in the TankII post ive got strange results - RX&TX speed is not balanced. ~46.7 mbps TX and 4.7 mbps RX
I use iperf for testing speed.
Have any ideas? When i mistake?

after investigation i've got commands bellow:
Code: [Select]
qos traffic-profile set port 1/1 name LIMITED meter-mode uniform-per-policy committed-rate 51200 committed-burst-size 1024 drop-out-action disable track-statistics aggregate
where 51200 - speed in kbps.

It's work on Olympic games!!!
...
Profit!

Nice job!  Glad that worked for you!
Now, can you bill by the bps?
