linkUp and linkDown

B-2
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)

– 1 COM Port
– 2 SDSL E1 Interface, Port 1
– 6 G.703 Interface, Port 1
ifAdminStatus (RFC 1573)
This object specifies the operational state of the interface:
– up(1)
SDSL Network: DSL link is established.
G.703: No alarm condition exists.
– down(2)
SDSL Network: DSL link is not established.
G.703: An alarm condition exists.
– testing(3)
A test is active on the interface.
