linkUp and linkDown
The link SNMP traps are:
linkUp – The unit recognizes that one of the communication interfaces is
operational.
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
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:
– 2
DSL E1 Interface, Port 1
– 3
DSL E1 Interface, Port 2
– 4
DSL E1 Interface, Port 3
– 5
DSL E1 Interface, Port 4
– 6
G.703, Port 1
– 7
G.703, Port 2
– 8
G.703, Port 3
– 9
G.703, Port 4
ifAdminStatus (RFC 1573)
This object specifies the operational state of the interface:
– up(1)
DSL Network: DSL link is established.
G.703: No alarm condition exists.
– down(2)
DSL Network: DSL link is not established.
G.703: An alarm condition exists.
– testing(3)
A test is active on the interface.
ifOperStatus (RFC 1573)
This object contains the same value as ifAdminStatus.
i
fType (RFC 1573)
This object is the type of interface:
– e1(19)
Used for the G.703 E1 interface.
