Standards Compliance for SNMP Traps
B-2
7970-A2-GB20-00 August 1999
linkUp and linkDown
The link SNMP traps are:
H
linkUp – The unit recognizes that one of the communication interfaces is
operational.
H
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/Down Variable-Bindings
H
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:
– 1 COM Port
– 2 M/xDSL Interface
– 6 DSX-1 or G.703 Interface
– 10 Synchronous Data Port
H
ifAdminStatus (RFC 1573)
This object specifies the operational state of the interface:
– up(1)
M/xDSL Network: DSL link is established.
DSX-1 or G.703: No alarm condition exists.
Synchronous Data Port: Port is enabled and both CTS and DSR are ON.
– down(2)
M/xDSL Network: DSL link is not established.
DSX-1 or G.703: An alarm condition exists.
Synchronous Data Port: Port is disabled or CTS or DSR is OFF.
– testing(3)
A test is active on the interface.
H
ifOperStatus (RFC 1573)
This object contains the same value as ifAdminStatus.
H i
fType (RFC 1573)
This object is the type of interface:
– T1(19) or E1(19)
Used for the DSX-1 or G.703 interface.
– propPointToPointSerial(22)
Used for the Synchronous Data Port and EOC.
– sdsl(96) or hdsl(96)
Used for the M/SDSL or M/HDSL network interface.
