Paradyne 8784 manual linkUp and linkDown

B. Standards Compliance for SNMP Traps

linkUp and linkDown

he link SNMP traps are:

linkUp – The unit recognizes that one of the communication interfaces is

Toperational.

linkDown – The unit recognizes that one of the communication interfaces is not operational.

The network and synchronous port interfaces (physical sublayer) are represented by an entry in the MIB-II interfaces table and supported by the DS1 MIB.

The following list describes the conditions that define linkUp and linkDown:

linkUp/DownT Variable-Bindings

ifIndex (RFC 1573)

This object provides the index into the ifTable and potentially into tables in other MIBs. The values of ifIndex are the same for all models, although not all indexes are supported for each model.

The ifIndex included with the trap consists of the slot number times 1000, plus:

–2DSL Network Interface, Port 1

–3DSL Network Interface, Port 2

–10DSX-1 Port, Port 1

T– 11DSX-1 Port, Port 2 ifAdminStatus (RFC 1573)

This object specifies the operational state of the interface:

–up(1)

DSL Network: DSL link is established.

Synchronous Data Port: Port is enabled and both CTS and DSR are ON.

–down(2)

DSL Network: DSL link is not established.

Synchronous Data Port: Port is disabled or CTS or DSR is OFF.

–testing(3)

A test is active on the interface.

ifOperStatus (RFC 1573)

TThis object contains the same value as ifAdminStatus. ifType (RFC 1573)

This object is the type of interface:

–propPointToPointSerial(22)

Used for the synchronous data ports and EOC.

–DS1(18)

Used for DSX-1 T1 interface

–HDSL(96)

Used for the HDSL network interface.
