Throttle

This field allows you to specify
the time delay, in milliseconds, between the trans-
mission of VLAN allocation requests to the Server.
The time delay is used to avoid placing an excessive
workload on the VLAN Server. The default setting
for this field is 50 milliseconds.
Poll Period This read-only field shows the time
interval, in seconds, between successive polls of the
VLAN Server. The Switch polls the VLAN Server
once every poll period to check for any changes.
