Monitoring Hub Performance 2-17
Using the TRMMIM Hub View
Link State Time
The time, in hours, minutes, and seconds, since the last Link State change.
Speed Fault
Indicates whether a ring speed fault has been detected at the selected station port.
Possible returned values are Fault Detected or No Fault Detected.
Note that if your hardware does not support this feature, this field will be grayed
out.
Insertion Trap
This configurable field indicates whether insertion (link) traps are enabled or
disabled for the station port. Insertion traps are generated by the TRMMIM when
a station inserts into the ring (i.e., the port status on the chassis changes from ENB
to INS) or removes itself from the ring (the port status changes from INS to ENB).
Note that your management system will only receive traps if your management
station’s IP address has been entered in the TRMMIM’s trap table. Refer to the
SPMA Tools Guide for more information on the trap table.
By default, these traps are disabled to reduce the amount of management activity
on your network.
To Enable/Disable the Insertion Traps:
1. Click mouse button 1 on the Enable or Disable option, as desired. Insertion
traps will either be activated or deactivated accordingly.
Checking Station Status
You can open a Station Status window for any station inserted into the ring. A
Station Status window provides information about the station inserted into a
station port interface on the MMAC hub. Note that if there is no station attached
to the monitored port, no information will display.
To open the Station Status window:
1. Click mouse button 3 in the station Port Status box to display the Station Port
menu.
NOTE
SPMA does not accept the trap messages; that task is left to your network management
system. (See the appropriate network management system documentation for details
about viewing trap messages.) When this utility is used in stand-alone mode, traps will
either be ignored when they return to the workstation from which you are running SPMA
for the TRMMIM, or they will turn up at another management workstation which has
been configured to accept traps. Note also that, regardless of the configuration performed
using this utility, NO traps will be sent by the TRMMIM unless its trap table has been
properly configured; see the TRMMIM hardware manual and/or the Trap Table chapter
in the SPMA Tools Guide for more information.
