snmp query VALUE/REGEXP issue help required

[annapatil]

Hi All,

I am polling LDP sessions details through below snmp data query, want to capture IP Address from VALUE/REGEXP (direction is kept input for testing purpose)


OID/REGEXP giving below output for LdpLocalIP and LdpRemoteIP

10.117.224.21.0.0.4294901761.10.117.226.15

required first 4 octates ( 10.117.224.21 ) as LdpLocalIP and last 4 octates as LdpRemoteIP (10.117.226.15)

Code: Select all

This is not gonna help you much, but i had trouble creating a regex for my xml too, but i just kept trying until it worked. I started with something very simple and incrementally tweaked it to get what i was looking for. I have a post in this forum too, take a look at that, maybe it will help you.
