collecting statistics snmp from virtual routers


Userlevel 2
Hi Guys,

I would like to know if is htere some way to collect information about traffic over virtual routers on x460, once i can't get it from vlans, or other way that you have been using to collect amount traffic over an specific vlan or virtual router.

Any suggest will be welcome.

Thank you.

Hi Welisson,

I hope i understood your requirement correctly.

And some supporting articles.

other question Karthik,
in this case it is showing me the values as frame or bytes, do you know how to pull out this information in Mbp/s?

Thank you

Hi Welisson,

I do not think there is a command to get these values in Mbps as most of the command outputs i see does fetch the values in Frames,Packets, Bytes or % *utilization.

Hi Karthik,

Actually I am not being able to find it out where I can pull out information such as Packets, or %Utilization, indeed I have found by frames and bytes, but this is a counter and it is increasing regarding how many bytes is going throught in this vlan, then, it would be usefull more for those one who wants to know about how many MB, GigaByte and so on, went to that vlan, for instance if I had to do data rate-limit.

If you can, please clarify me where can i find out those information in order to get statistic of traffic in some vlan?

I would like to use mrtg/cacti or whatever frontend like that.

Hi welisson,

As far as i have checked i guess the "sh port vlan statistic" is limited to frames and packet size in Byte.

In my previous post i meant that i have not seen a command output that will display Mbps and is not specific to the vlan statistics, i hope this clarifies.

Hi Karthik,

Yep, it is clear. So what i would like to say about bits/s, if you were able to find out another mib in which we could get this information, or is it not possible?

sorry for the late reply Welisson, so far i could not find a OID or a command to get the VLAN statistics in bits

No Problem Karthik,

So, let me ask a question about that.

Would you be able to collect or create a graphic based in bits/s, using any other way?

thank you.
Cheers,

Hi Welisson,

Are you looking for the bits/s very specific to VLAN statistics or the generic port utilization?
Userlevel 2
Hi Karthik,

Yep, because port utilization we can use a mib IfHOct, but i couldn't find to vlan.

Hi Welisson,

I could only see the below as Supported Variables for the Vlan Stats.


I guess the bits/s is something not available at this time and if this is something essential then please get in touch with Extreme Sales channel to raise this as a Feature request.
