Using SNMP to monitor interface status

Sam_Gribbs

Currently having issues with snmpget pulling the status of an interface.

 

https://support.f5.com/csp/article/K01528351

 

This link details that running an snmptranslate for the OID of a particular interface returns an OID as such:

# snmptranslate -On F5-BIGIP-SYSTEM-MIB::sysInterfaceStatus."1.1"

      .1.3.6.1.4.1.3375.2.1.2.4.1.2.1.17.1.1

 

However when trying to run either an snmpget *or* snmpwalk for this OID it will return with

snmpwalk 127.0.0.1 -c public -v2c .1.3.6.1.4.1.3375.2.1.2.4.1.2.1.17.1.1  

F5-BIGIP-SYSTEM-MIB::sysInterfaceStatus."." = No Such Instance currently exists at this OID

 

Downloading the MIB files to examine the System MIB has not revealed any clues as to why this is the case. Documentation shows that there should be a return of integer values:

 

sysInterfaceStatus OBJECT-TYPE 

SYNTAX INTEGER {

up(0),

down(1),

uninitialized(3),

unpopulated(5)

}

MAX-ACCESS read-only

STATUS current

DESCRIPTION

"The current state of the specified interface.

up      - has link and is initialized;  

down     - has no link and is initialized;

uninitialized - has not been initialized;

unpopulated  - interface not physically populated."

::= { sysInterfaceEntry 17 }

Hello Sam.

 

Mapping OID could be changed. Try to query a higher OID in the MIB hierarchy. For example:

snmpwalk 127.0.0.1 -c public -v2c F5-BIGIP-SYSTEM-MIB::sysInterfaceStatus
