Module: ZHONE-COM-PPP-MIB

OID (symbolic): ZHONE-COM-PPP-MIB::ncpExtVJCompSlotID

OID (numeric): 1.3.6.1.4.1.5504.4.5.3.1.2

Node type: OBJECT-TYPE

Type: EnableFlag

What is ncpExtVJCompSlotID?

A switch, disabled by default, controlling whether the VJ header-compression slot identifier field itself may be compressed (omitted from every packet) versus always being included; an admin enables it to squeeze slightly more overhead out of VJ-compressed TCP traffic.
