SNMP OID Monitoring active internet channel

Basyuk — Thu, 05 Nov 2020 08:48:37 GMT

I have two internet channel on Checkpoint 1430.

ISP Redundancy was config in High Availibility mode.

How can I get information about active channel at the moment. I don't find OID for this task.

Help me, please.

I am very interested in this question because I ask myself the same in R80.40 on openserveur.

Perhaps using a custom oid with a script ...

If I am right, ISP redundancy acts by changing the default route, so you can perform a snmpwalk to some OID of the routing table that includes the default route, maybe this one:

snmpwalk -v1 -c community -On localhost .1.3.6.1.2.1.4.24.4.1.4.0.0.0.0
.1.3.6.1.2.1.4.24.4.1.4.0.0.0.0.0.0.0.0.0.x.y.z.t = IpAddress: x.y.z.t

and it should return the ip address of current next hop. If the primary ISP is down, the OID should change to the nexthop of the second ISP.

If you don't want to perform a snmpwalk, you can perform two snmpgets, each one to the OID of the next hop of one of the ISPs. The snmpget that returns a value would be the ISP that is acting as primary, the other should return a "There is no such variable name in this MIB" error.
