Statistics are not accurate on a beaconing ring. To correct this
condition, resolve beaconing and then clear all statistics. This is normal
operation.
Setting Beacon
Threshold
Use the SET MODULE BCN_THRESHOLD to set the number of times
that a phantom transition, caused by a beaconing condition, is allowed
to cause a port or trunk to unwrap before the port or trunk is removed
from the ring.
The command sequence is:
SET MODULE {slot}.1 BCN_THRESHOLD {threshold}
Where:
{slot}.1
= module 1 to 17, subslot 1
{threshold} = 0 to 255 phantom transitions
The following command sets the beacon threshold of the Active Per
Port Module in slot 7 to a maximum of 7. If this threshold is exceeded
for a port or trunk, that port or trunk is removed from the ring:
CB5000> set module 7.1 bcn_threshold 7 [ENTER]
Threshold set to 7.
The default value for Set Beacon Threshold is 7. A value of 0 (zero)
means infinite, therefore you will never reach the maximum threshold
value.
Enabling Static Ring
Switching
Use the SET PORT STATIC_SWITCH to:
■
Force users to power down a station before switching rings or
networks.
This forces the station to perform a duplicate address test before
entering a new ring.
■
Prevent ports from being switched from one ring to another when a
phantom is present.
This command applies only to port switching modules.
