'Is device currently reachable via SNMP' attribute

[Frank Tonjes]

This might seem like a basic question (and it probably is!) but is there any attribute in Spectrum which tells me if the device is currently reachable via SNMP and if it's reachable via ICMP?

 

I know Contact Status stays 'Established' if the device is still reachable via ICMP but not SNMP. I need to know if there is a way to determine this via attributes.

 

I know you can find this by looking at alarms for the device but I don't want to have to find all devices with the alarm 'MANAGEMENT AGENT LOST'.

 

I'm hoping to do one query which tells me if a device is accessible via ICMP and/or SNMP.

 

Note: I don't want to have to do a PING and/or snmp poll either.  This will take ages if I do a query on 100+ or more devices if I have to do this on demand!

 

Surely this should be somewhere in Spectrum but I can't find it

Thanks,

Frank

Dev_Contact_Status (0x110ed) is the attribute you are looking for

Thanks, I'll check it out today.

Hi Roger_Nason,

 

Is a pingable device reachable via SNMP?

I say that because the value of the attribute you mentioned "Dev_Contact_Status" on a pingable device and on a router monitored via SNMP (i.e. Rtr_Cisco) is the same, iqual to 1.

No, a Pingable model is not reachable via SNMP. However, on SNMP-capable models, the Dev_Contact_Status attribute reflects the SNMP contact status, while Contact_Status reflects ICMP contact. So on an SNMP device where Spectrum cannot communicate with the SNMP agent, but can ping the IP, Contact_Status will be 1 and Dev_Contact_Status will be 0. Under normal conditions, agent up and IP reachable both attributes will be 1. On a Pingable model Dev_Contact_Status reflects ICMP contact only.

Got it! Thanks Roger_Nason!
