network::dlink::standard::snmp::plugin --mode=interfaces

[sunks08]

Hello,

i'm using a command to display the traffic on each ports of my dlink switch and i would like to add the vlan of the port.

The command is : --plugin=network::dlink::standard::snmp::plugin --mode=interfaces --hostname=$HOSTADDRESS$ --interface=x

I tried to add "--oid-extra-display=x.x.x.x.." but i get "UNKNOWN: Unsupported oid in --oid-extra-display-option"

I'm not sure to understand how this option is working and if it's possible to display the vlan of each port. It would be really awesome if i could !

I found the oid that give the VLAN number of the port, it's this one : 1.3.6.1.2.1.17.7.1.4.5.1.1.x the x mean the port number we want to display

Thanks !

I think this is a standard OID by the way

The index is the IfIndex of your interface ? You can have X Vlan for the same interface also no ?

what i found about the OID 1.3.6.1.2.1.17.7.1.4.5.1.1: "The PVID, the VLAN ID assigned to untagged frames or Priority-Tagged frames received on this port."

Untagged frames means that you can have only one vlan, so it will display only one vlan for each port (or all port if you don't add the number of the interface). I guess it's an other OID for trunk port (tagged). I'll check monday if i can find something about that

To resume: With that OID when i do a "snmpwalk -v2c -c public xx.xx.xx.xx 1.3.6.1.2.1.17.7.1.4.5.1.1" It display the PVID (Port Vlan ID) of every interface and when theire is X vlan for the same interface it just display vlan 1 for me (wich is ok for now).

example for 1 interface: "snmpwalk -v2c -c public xx.xx.xx.xx 1.3.6.1.2.1.17.7.1.4.5.1.1.x SNMPv2-SMI::mib-2.17.7.1.4.5.1.1.x = Gauge32: 10"

So for the interface x, the vlan ID is 10.

If it's possible to add this option in the --plugin=network::dlink::standard::snmp::plugin --mode=interfaces it would be awesome.

thanks

Excuse me for the late response. If you still have the issue, could you provide me a snmpwalk with VLAN informations. snmpwalk -ObentU -v 2c -c public IP .1.3.6.1.2 > dlink.snmpwalk

Hello :)

Without additional information we are not able to provide a solution or resolve a possible bug. So @sunks08 if you still need a response / solution to this issue, can you provide us the snmpwalk asked by Quentin ? Otherwise we will be forced to close this issue.
