snmpget problem with ltmPoolMemberPort = 0

Hi folks,

 

 

I've got a problem with the snmp polling of a LTM :

 

 

I'd like to monitor the status of a pool member (with snmp) to see if it has been deactivated by its health monitor :

 

 

 

- I'v seen the following entry with snmpwalk :

 

$ snmpwalk -v2c -c xxxx ltmhost .iso.org.dod.internet.private.enterprises.f5.bigipTrafficMgmt.bigipLocalTM.ltmPools.ltmPoolMember.ltmPoolMemberTable.ltmPoolMemberEntry.ltmPoolMemberSessionStatus | grep 10.255.1.28

 

 

F5-BIGIP-LOCAL-MIB::ltmPoolMemberSessionStatus."MyPool".ipv4."10.255.1.28".0 = INTEGER: enabled(1)

 

 

 

 

- When trying to get it with snmpget I ran into the following problem :

 

 

$ snmpget -On -Oq -Oe -v2c -c xxxx ltmhost .iso.org.dod.internet.private.enterprises.f5.bigipTrafficMgmt.bigipLocalTM.ltmPools.ltmPoolMember.ltmPoolMemberTable.ltmPoolMemberEntry.ltmPoolMemberSessionStatus.\"MyPool\".ipv4.\"10.255.1.28\".0

 

.iso.org.dod.internet.private.enterprises.f5.bigipTrafficMgmt.bigipLocalTM.ltmPools.ltmPoolMember.ltmPoolMemberTable.ltmPoolMemberEntry.ltmPoolMemberSessionStatus."MyPool".ipv4."10.255.1.28".0: Unknown Object Identifier (Index out of range: 0 (ltmPoolMemberPort))

 

 

 

It refuses the value of 0 for the ltmPoolMemberPort (althought it appears in the output of the previous snmpwalk). This value of zero correspond to a pool member wich has a service port of "any" (wildcard).

 

 

- I looked into the MIB and the "out of range" error looks right :

 

ltmPoolMemberPort OBJECT-TYPE

 

SYNTAX INTEGER(1..2147483647)

 

 

 

-> Finaly... what is wrong with my snmpget and how can I get the value of ltmPoolMemberSessionStatus when the pool member has a zero service port ?

 

 

Thank you for your help!
