F. 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.
AUX 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 down(2).
	The interface is never in the testing(3) state.
MODEM 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) when the modem is
	connected and down(2) when the modem is not connected.
	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.
