how do I get IP address contained within the OID

[gregtompkins]

Hello,

I have routers and IP addresses are stored in the OID. For example:

[root@server1 ~]# snmpwalk -Os -cpublic -v2c 192.168.1.1 ipAdEntIfIndex
ipAdEntIfIndex.11.22.33.144 = INTEGER: 2
ipAdEntIfIndex.127.0.0.1 = INTEGER: 1
ipAdEntIfIndex.192.168.1.1 = INTEGER: 3
ipAdEntIfIndex.192.168.11.1 = INTEGER: 4

I set up the Item like in the attachment but it comes back "Not Supported"

What am I doing incorrectly?

Thank You!

Try to change "Type of information" from Character to Text

Try to change "Type of information" from Character to Text

I'm pretty sure that won't fix it.

@gregtompkins:
You'll have to find an OID or OID tree, where it has the IP address as the value and not part of the OID. I've never seen the IP address encoded into the OID before...

I suppose you can always write a script that performs an SNMPWALK and then performs some operation with grep/awk/sed to obtain just the IP address from the OID.

Do you have any error? See: list of items (=host items), column error, popup message on error icon.
Did you wait after update of "Type of information" - default refresh time for unsupported items is 600sec. Or you can try disable/enable item after update.

Yes, I got an error.... I changed it to "Text" the last part of the OID contains the IP addresses of the interfaces and the value = 1,2,3,4 corresponds with the Interface lo, eth0, eth1, eth2. I know, it would be "easy" if it was OID = IP address but in my case it's OID.IPADDRESS = interface #x
