frame-relay bc >
Use the frame-relay bc command to set the b
c
(committed burst) value for a Frame Relay sublink. The
value is in bits. Use the no form of this command to return to default.
Syntax Description
Specifies the committed burst value (in bits) for the sublink.
Default Values
By default, the committed burst value is set to 0 (no limit).
Applicable Platforms
This command applies to the NetVanta 1000R, 3000, 4000, and 5000 and Total Access 900 Series units.
Command History
Release 4.1 Command was introduced.
Functional Notes
The time interval is always one second, so this can also be considered bits per second. Shaping is
performed on a sliding one-second window to make maximum use of configured bandwidth. Note that
when both b
c
and b
e
are non-zero, shaping is performed on the virtual circuit. The circuit is limited to the
sum of b
c
and b
e
, and it is recommended that the sum always be greater than 8000.
Usage Examples
The following example configures the Frame Relay sublink with a committed burst value of 128,000 bits:
(config)#interface frame-relay 1.1
(config-fr 1.16)#frame-relay bc 128000
