Configuring Bandwidth Allocation Groups
To optimize frame relay bandw idth use, vario us types of interfaces can be assigned to
one of sixteen bandwidth allocation groups, each defined by the parameters listed in
Table 7-1 (on page 7-7). Bandw idth all o cati on grou ps c an ens ur e that r espons e time -
sensitive traffic gets access to the available frame relay bandwidth.
Each of the following entities that use a frame relay port can be assigned (in the
database records) to a bandwidth allocation group:
●Node (for u se in sessions wi th a NetView host )
●Logic al port
●SNA Port (LLC2 parameters)
●IP interface
●IPX interface
●LLC2 host
●LLC2 interface
●Bridge port
For further control, bandwidth allocation can be enabled or disabled on each frame
relay port.
This feature is applied only when a line's available bandwidth is limited
(i.e., packets must be queued before transmission).
Also note that bandwidth allocation is not applied in a frame relay
passthrough configuration (frame relay PVCs into and out of the Smart-
Switch, internal PVC between the two frame relay ports). (Although the
SmartSwitch supports bandwidth allocation, routers and FRADs that ini-
tiate f rame re lay pas sthro ugh do no t.)

Be sure you fully understand the needs of the users of the node

before assigning allocation groups; this feature can show adverse

effects if configu red inco rrectly.

Be sure to configure the same bandwidth allocation values at

both ends of a connection between SmartSwitch 1800s.

To conf igure a band width allo cation group, pres s [H] at the No de Config ur a t ion Menu
(or [A], [A], [H] from the Main Menu). A screen similar to the following will be dis-
played.
