Configuring Bandwidth Allocation Groups
7-6
To optimize frame relay bandwidth use, various types of interfaces can be assigned to
one of sixteen Bandwidth Allocation Groups, each defined by the parameters listed in
Table
7-1. Bandwidth Allocation Groups can ensure that response 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 use in sessions with a NetView host)
Logical 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 FRM,
internal PVC between the two frame relay ports). (Although the FRM sup-
ports bandwidth allocation, routers and FRADs that initiate frame relay
passthrough do not.)
Be sure you fully understand the needs of the users of the node
before assigning allocation groups; this feature can show adverse
effects if configured incorrectly.
Be sure to configure the same DLCI
and bandwidth allocation values at both ends of a connection
between FRM devices. The parameters should be configured to
handle the heavier traffic volume.
To configure a Bandwidth Allocation Group, press
Menu (or
from the Main Menu). A screen similar to the following will be
[A], [A], [H]
displayed.
