WCP Interface Parameter Descriptions

Use the following descriptions as guidelines when you conﬁgure the WCP

interface parameters.

Parameter: Enable

Default: Enable

Options: Enable | Disable

Function: Enables or disables data compression on the circuit.

Instructions: WCP automatically sets this parameter to Enable when you select WCP in

the Select Protocols window. If you want to temporarily disable WCP

rather than delete it from the platform, set this parameter to Disable. Reset

it to Enable to re-enable WCP.

MIB Object ID: 1.3.6.1.4.1.18.3.4.22.2.1.2

Parameter: Compression Mode

Default: Inherit from Line

Options: Continuous Packet | Packet by Packet | Inherit from Line

Function: Indicates the compression mode on the circuit.

Continuous Packet Compression (CPC) retains compression history

across packets and allows a higher compression ratio than does Packet-

by-Packet Compression (PPC).

PPC resets compression history at the start of each packet, resulting in a

lower compression ratio. Since PPC does not depend on previous packets,

you should select this option for a link that drops a large number of

packets.

Inherit from Line allows you to set WCP parameters at the line level and

apply them to circuits. For PPP, with only one circuit per line, this means

that you can conﬁgure WCP at either the circuit level or the line level.

Instructions: Select Inherit from Line if you want to accept the value in effect for the

WCP Compression Mode line parameter. Otherwise, select either

Continuous Packet or Packet by Packet.
