Getting L3 Statistics from a 7432CQ

[Kurz-Weber]

Hi there,

as a newcomer to Extreme Networks (previously working with Juniper & Alcatel), I really struggle to make some requests to work. For capacity-management I need to find out, what each configured network ip interface is utilizing. It is not enough to say, what the physical interface is doing. We need it to find out flows betwen networks and their utilizations and peaks.

Our environment looks like this:

1. We're using VSP Series 7400
2. Whole Backbone is deployed in Fabric-Mode.
3. One Fabric-Member is doing Routing and has all Gateways of all VLANs, which are in our Fabric.

We have multiple tools like XIQ, PRTG or Scrutinizer available. With PRTG is can successfully receive/poll interface statistics from physical interface. Unfortunately no data can be access per vlan.

Maybe I'm going about it completely the wrong way and I hope, you might enlight me.

Thanks in advance!

If you have Scrutinizer configure sFlow on the 7400 to get sampled statistics on all conversations through the box. Then in Scrutinizer you'll be able to search and filter for specific flows or source/destination networks.

Hi Steven,

thank you very much for your example. I freely adapted your configer-snippet and unfortunately it seems like, it isn't working.

VSP7400:1(config)#filter acl 4 type inVlan name "VLAN4stats"
VSP7400:1(config)#filter acl vlan 4 4
VSP7400:1(config)#filter acl ace 4 1
VSP7400:1(config)#filter acl ace action 4 1 permit count
VSP7400:1(config)#$ ace ethernet 4 1 dst-mac mask 00:00:00:00:00:00 0xffffffffffff
VSP7400:1(config)#filter acl ace 4 1 enable
VSP7400:1(config)#
VSP7400:1(config)#end
VSP7400:1#show filter acl statistics 4 1

 Did I miss something?

I keep losing my notes on how to do that...!

So again, I have a VLAN 203 on my VSP7400 switch, so I create this filter:

VSP7448-1:1(config)#[v74]% cfg||acl
               alias[v74]% show running-config -bi ||acl
config terminal
filter acl 203 type inVlan name "VLAN203stats"
filter acl vlan 203 203
filter acl ace 203 1
filter acl ace action 203 1 permit count
filter acl ace ethernet 203 1 dst-mac mask 00:00:00:00:00:00 0xffffffffffff
filter acl ace 203 1 enable
end

And now I have byte and packet counters for all traffic entering that VLAN:

VSP7448-1:1(config)#[v74]% show filter acl statistics 203 1

And you can also pull those stats from these MIBs:
