3Com 2200 manual Setting Neighbor Notification Timer, Enabling Disabling Status Reporting

Administering FDDI Stations 8-5

Setting Neighbor Notification Timer

The T-notifyattribute 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-notifytimer:

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.
