Configuring Frame Relay Services
A-28 117376-B Rev. 00
Parameter: Hybrid Mode
Path: Configuration Manager > Protocols > Frame Relay > Services > PVCs
Default: OFF
Options: ON
| OFF
Function: Allows you to use the same PVC for both routing and bridging.
Instructions: If you do not want to enable both routing and bridging services, accept the
default, OFF. If you do want to enable both routing and bridging, set to ON.
MIB Object ID: 1.3.6.1.4.1.18.3.5.9.1.2.1.24
Parameter: Committed Burst
Path: Configuration Manager > Protocols > Frame Relay > Services > PVCs
Default: 0
Options: 0 to 2,147,483,647 bits
Function: The maximum number of bits that a VC can transmit during the VC’s burst
period (Tc) when congestion is occurring. To enable traffic shaping, this
parameter and the Throughput parameter (CIR) must both be greater than zero.
The Committed Burst (Bc) value should be lower than the Throughput.
Instructions: Enter a value within the given range. You should set this parameter to 1/4 of the
CIR unless this VC is sending frames larger than that size. If the VC is sending
large frames, increase the value of this parameter to accommodate the size of
those frames.
MIB Object ID: 1.3.6.1.4.1.18.3.5.9.9.2.1.16
Parameter: Excess Burst
Path: Configuration Manager > Protocols > Frame Relay > Services > PVCs
Default: 0
Options: 0 to 2,147,483,647 bits
Function: This value is added to the Committed Burst value to determine the maximum
number of bits that may be transmitted during the VC’s burst period when there
is no congestion. The Excess Burst plus the Committed Burst must be less than
or equal to the line speed.
Instructions: Enter a value within the given range.
