Configuring Bandwidth Allocation Groups
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 FRX
node, internal PVC between the two frame relay ports). (Although the
FRX4000 and FRX6000 support 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 rate control (see page 7-12)
and bandwidth allocation values at both ends of a connection
between Cabletron frame relay access devices. The parameters
should be configured to handle the heavier traffic volume.
To configure a Bandwidth Allocation Group, press
[H]
at the Node Configuration
Menu (or
[A], [A], [H]
from the Main Menu). A screen similar to the following will be
displayed.
