Configuring Header De-Duplication (CLI)
Note:
For IP-20E and IP-20V, Header De-Duplication is available for all
channels except 500 MHz. Make sure to disable Header De-Duplication
before selecting a 500 MHz MRMC script.
Header De-Duplication identifies traffic flows and replaces header fields with a
flow ID. The Header De-Duplication module includes an algorithm for learning
each new flow, and implements compression on the flow type starting with the
next frame of that flow type.
You can determine the depth to which the compression mechanism operates,
from Layer 2 to Layer 4. You must balance the depth of compression against the
number of flows in order to ensure maximum efficiency. Multi-Layer (Enhanced)
compression supports up to 256 flow types.
Note:
The Header De-Duplication configuration must be identical on both
sides of the link.
To configure Header De-Duplication, enter the following command in radio view:
radio[2/1]> compression header-compression set <mode>
Note:
In this release, if two radio carriers in an IP-20C or IP-20C-HP unit are
activated, the Header De-Duplication configuration for radio carrier 1
are applied to both carriers. You must enter radio view for radio
interface 1.
To clear Ethernet port counters, including both Frame Cut-Through and Header
De-Duplication counters, enter the following command in radio view:
radio[x/x]>clear-ethernet-port-counters
