SNMP MIB Objects

Interface Group – “ifOperStatus” Object (ifEntry 8)

This object specifies the current operational state of the interface. The value of this object for each interface is defined as follows:

Network T1:

The interface is up(1) when no alarm conditions exist.

 

The interface is down(2) when an alarm condition is active.

 

The interface is testing(3) when a test is active on the

 

interface.

DTE T1:

The interface is up(1) when no alarm conditions exist and

 

the interface is enabled.

 

The interface is down(2) when an alarm condition is active

 

and the interface is disabled.

 

The interface is testing(3) when a test is active on the

 

interface.

COM Port:

When configured as an SNMP management link, up and

 

down are based on the current state of the link layer

 

protocol. Otherwise, the interface is always up(1).

 

The interface is never in the testing(3) state.

Data Ports:

The interface is up(1) when the port is assigned to a T1

 

interface or another data port as a backup, and both CTS

 

and DSR are ON.

 

The interface is down(2) when the port is unassigned, or

 

either CTS or DSR is OFF.

 

The interface is testing(3) when a test is active on the

 

interface.

Interface Group – “ifLastChange” Object (ifEntry 9)

This object contains the value of “sysUpTime” at the time the interface entered its current operational state.
