Administering FDDI Stations 8-5
Setting Neighbor
Notification Timer
The T-notify attribute is a timer used in the Neighbor Notification protocol
to indicate the interval of time between the generation of Neighbor
Information Frames (NIF). NIF frames allow stations to discover their
upstream and downstream neighbors. The T-notify value has a range
of 2 to 30 seconds, with a default value of 30 seconds.
By setting the T-notify value low, your network reacts quickly to station
changes, but more bandwidth is used. By setting the T-notify value high,
less bandwidth is used, but your network does not react to station changes
as quickly.
To set the T-notify timer:
1 From the top level of the Administration Console, enter:
fddi station tNotify
You are prompted for a station. The Switch 2200 has one station, which
appears in brackets.
2 Press Return.
3 Enter the value of the T-notify timer for that station.
Valid values are 2–30 seconds.
See the following example:
Select station [1]:
Station 1 - Enter new value [30]:
Enabling and
Disabling Status
Reporting
The statusReporting attribute controls whether a station generates Status
Report Frames (SRFs) to report events and conditions to network
management stations. By default, status reporting is enabled. If you do not
have an SMT management station listening to these event reports or if you
use SNMP to monitor FDDI events on all FDDI end-stations, you can set this
attribute to disabled so that SRFs will not be generated by the station.
To enable or disable status reporting for a station:
1 From the top level of the Administration Console, enter:
fddi station statusReporting
You are prompted for a station. The Switch 2200 has one station, which
appears in brackets.
