Dell N4064F snmp monitoring problem

Hi,

I use PRTG for monitoring and it cannot get the physical interface info and bandwidth of Dell N4064F.

It can get the system info: Dell Networking N4064F, 6.5.1.6, Linux 3.7.10-f04fdef1

Here is the snmp configuration of switch:

snmp-server location "SAN ISIDRO"
snmp-server contact "VTTEK"
logging snmp
snmp-server engineid local 800002a203e4f004aa4173
snmp-server community "vOCS3.0" ro
snmp-server host 10.121.20.174 traps version 2 "vOCS3.0"
snmp-server host 10.121.62.70 "vOCS3.0"
snmp-server host 10.121.62.71 "vOCS3.0"
snmp-server enable traps bgp state-changes limited
snmp-server enable traps dvmrp
snmp-server enable traps pim
snmp-server enable traps captive-portal
snmp-server enable traps captive-portal client-auth-failure
snmp-server enable traps captive-portal client-connect
snmp-server enable traps captive-portal client-db-full
snmp-server enable traps captive-portal client-disconnect

 

many thanks,

5 Practitioner

It sounds like the SNMP portion is working, as the switch is reporting some information? What OID is being polled, but is not responding? Have you tried importing the MIBs into PRTG?

The MIB file is included with the switch firmware download.

If you are getting the sysinfo from SNMPv2, then you should be able to get the interface info as well.  It looks like the SNMP settings you have will work, you really only need the community string.  The host commands for .70 and .71 will limit access to just those two hosts.  You will want to use the oids from the IF-MIB.  IF (InterFace) should give you the information you are looking for for the individual physical interfaces on the switch.  I believe it also provides LAG information if you have aggregate links.  Import the IF-MIB into PRTG.

Hope this helps.
