SNMP MIB Objects

E-53160-A2-GB22-10 December 1996

Interface Group – “ifAdminStatus” Object

(ifEntry 7)

This object specifies the desired state (configuration)

of the interface. This object is supported only for the

MODEM port. It provides the ability to switch between

using the MODEM port as the SNMP management link

and ASCII operations (Dial-out, FPE). Refer to the 3100

Series device document for more information. The value

of this object will not affect the state of any of the

interfaces on the T1 DSU/CSU other than the MODEM

port. Only the following values are supported by the

DSU/CSU:

• up(1) – The SNMP management link is active on

the MODEM port (i.e., the Modem Use

configuration option is set to SNMP).

• testing(3) – The SNMP management link is inactive

on the MODEM port and can be used for

proprietary ASCII functions.

• 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.

DTE

Drop/Insert T1:

The interface is up(1) when no

alarm conditions exist and the I/F

is enabled.

The interface is down(2) when an

alarm condition is active and the

I/F is disabled.

The interface is testing(3) when a

test is active on the interface.

COM Port:

When configured as the 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.

MODEM Port: When configured as the 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

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 – Input Counters

(objects ifEntry 10 to ifEntry 15)

The

objects used to collect statistics on the data

received by an interface apply only to the COM port and

the MODEM port when the port is configured as the

SNMP management link. For interfaces that are not

configured as the SNMP management link, these statistics

are not provided and an error status is returned if access is

attempted. The objects used to collect input statistics are

listed below:

• ifInOctets (ifEntry 10)

• ifInUcastPkts (ifEntry 11)

• ifInNUcastPkts (ifEntry 12)

• ifInDiscards (ifEntry 13)

• ifInErrors (ifEntry 14)

• ifInUnknownProtos (ifEntry 15)
