Set User Filter Address – Displays the current User Filter IP
addresses. Allows you to enter up to 8 IP addresses to be used if
the User Defined Addresses Only option was selected in the User
Filtering Option above.
The default for all addresses is 0.0.0.0.
Set User Filter Mask – Displays the current masks. Allows you
to enter subnet masks for each of the User Filter IP Address
entries.
The default for all subnet masks is 255.0.0.0.
Set User Filter Range – Defines a range of addresses for each of
the User Filter IP Address entries (the range includes the base
address).
Valid values: 0 – 255.
The default value is 0 (not used).
NOTES:
You may use either Mask or Range (but not both) to define a group of user filter
addresses.
If IP broadcast packets should reach the devices connected behind the SU unit,
the Broadcast IP address should be included in the configured User Filter
Address entries.
Delete a User Filtering Entry – Displays the current list of IP
addresses, subnet masks and ranges. Enter the list number
(from 0 to 7) to delete the entry from the list (the list number will
be replaced by the default values).
Delete All User Filtering Entries – Deletes all User Filtering
entries (and replaces them with the default values).
Show All User Filtering Parameters – Displays the current
User Filtering Option and the list of User Filtering addresses,
subnet masks and ranges.
MIR and CIR Parameters – The CIR (Committed Information Rate)
value specifies the minimum data rate guaranteed to the applicable
subscriber. The MIR (Maximum Information Rate) value specifies
the maximum data rate available for burst transmissions, provided
such bandwidth is available.
Under normal conditions, the actual Information Rate (IR) will be
between the applicable CIR and MIR values: IR=CIR+K(MIR-CIR),
where K is between 0 to 1 and is determined dynamically by the AU
according to overall demand in the cell and the prevailing conditions
