B-2
May 2002 8700-A2-GB20-40
For a unit defined as an NTU running IP Conservative software, all traps have at a
minimum a variable binding of the Super Overloaded ifIndex (SOI). The formula
for the SOI is:
((LTU Slot Number) * 1,000,000)
+ ((LTU DSL Port Number) * 1,000)
+ the NTU’s ifIndex.
warmStart
authenticationFailure
linkUp and linkDown
The link SNMP traps are:
linkUp
– The unit recognizes that one of the communication interface is
operational.
linkDown
– The unit recognizes that one of the communication interface 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.
