Nexus 5596up, performance n55-m160l3

[dijix1990]

I have nexus 5596up with module n55-m160l3, and I'm interesting how can I see how much traffic goes through n55-m160l3? Maybe there is something command for it?

Hi @dijix1990 

That's the L3 daughter card. I do not have one around to check internal commands, but because only routed traffic is sent to the module, one way to verify the volume of traffic sent to it, is to monitor the statistics of SVIs.

Cheers,

Hi, but nexus doesn't give statistic from vlan interfaces over snmp, and I
can't see that in cli too, show interface vlan 100 doesn't give information
about traffic.... (

[Sergiu.Daniluk]

Hi @dijix1990 

Try the command:

show interface vlan <id> counters 

If it doesn't work, could be possible that you have an old NXOS release. Try an upgrade and very afterwards.

Cheers,

Oh, I'm going to try it tomorrow, thanks for help, maybe you know if the
nexus can give vlan counters over snmp oid Such as ifhcinoctets

[dijix1990]

unfortunately it doesn't work, and i installed last firmware for N5K-C5596UP a long time..

sh int vlan 2198 counters

Do you have L3 license installed?

Is there any routed traffic on vlan 2198? Note that ONLY routed traffic is displayed here.

Normally the counters listed in "show interface counters" can be also translated in SNMP counters.

[dijix1990]

of course, we use nexus as L3 core (Release 7.3(8)N1(1) 

)

Do you see the same results on all SVIs with the command "show interface counters | grep Vlan"?

[dijix1990]

yes the same results for all SVIs, I think it maybe a bug, I'm going to try new firmware 7.3(11)N1(1) 

[Sergiu.Daniluk]

Yep, better check the newest firmware. Let us know the results after the upgrade.

Take care,

Sergiu

[Sergiu.Daniluk]

Can you also check this command:

show interface counters detailed snmp

Cheers,

Sergiu

[dijix1990]

yes, I did it too, counters are zero
