Get Graphs Form L3 VLANS on Nexus 9K,3K

[admin@atrinnet.net]

Hi

If get command show interface vlan 3

Vlan 3 has layer 3 vlan and Have traffic 

For nexus  in prtg cacti zabbix Donnot able to get Graphs Form VLANS

Any idea For Solve this ?

[balaji.bandi · Accepted solution]

what version of nexus, what SNMP version you using ?

if this is Layer3 VLAN with IP address, most of the NMS can monitor that VLAN Traffic (but default the VLAN SVI set to 1GB only, so if the traffic going more than that you get warning, you need to increase VLAN Interface bandwidth to fix that)

Version 2 traffic under 1G

[balaji.bandi]

Version 2 traffic under 1G

before snmp get any data, you should see first on cli what kind of packet in and out, as i showed the output.

not sure is this bug at this stage, as suggested try increasing vlan interface bandwidth to more and issue show interface vlanx see you able to see the packets

Use debugging and troubleshooting tools provided by the monitoring platforms to diagnose any issues with VLAN monitoring. Check for error messages, SNMP queries, and data collection processes to identify any potential problems.

i see your TX load full :  ( try increase the bandwidth on SVI and monitor)

or this could be bug :
