SNMP MIB Objects

Interface Group – “ifType” Object (ifEntry 3)

This object identifies the type of the interface based on the physical/link protocol(s) immediately below the network layer. Only the following values are supported by the DSU/CSU:

Hds1 – Used for the network and DTE Drop/Insert (DSX-1) interfaces.

HpropPointToPointSerial(22) – Used for the synchronous data ports. Used for the COM port when the port is not configured as the SNMP management interface.

Hppp(23) – Used for the COM port when the port is configured for PPP.

Hslip(28) – Used for the COM port when the port is configured for SLIP.

Interface Group – “ifMtu” Object (ifEntry 4)

This object identifies the largest datagram that can be sent or received on the interface. It is applicable only to the interface configured as the SNMP management link. This object is zero for all other interfaces.

Interface Group – “ifSpeed” Object (ifEntry 5)

This object provides the interface’s current bandwidth in bits per second. The value of this object for each interface is specified as follows:

T1 Interfaces:	1,544,000 bps.
COM:	The currently configured data rate for the port.
Data Ports:	The currently configured data rate for the port when the port
	is allocated to one of the T1 interfaces. If the port is not
	allocated the data rate is defined as zero.

Interface Group – “ifAdminStatus” Object (ifEntry 7)

This object specifies the desired state (configuration) of the interface. This object is supported only for the COM port. It provides the ability to switch between using the port for SNMP or ASCII operations (dial-out, front panel emulation). The value of this object will not affect the state of any of the interfaces on the DSU/CSU other than the COM port. Only the following values are supported by the DSU/CSU:

Hup(1) – The SNMP management link is active on the COM port.

Htesting(3) – The SNMP management link is inactive on the COM port; the COM port can be used for proprietary ASCII functions.
