Displaying Payload Header Suppression Entries
Use the show cable qos svc-flow phs command in Privileged EXEC mode to display
the Payload Header Suppression (PHS) entries for a service flow, as shown below:
MOT#show cable qos svc-flow phs {<x>/<y>} [<1-4292967295> | <cr>] [1-65535> |
<cr>]
where:
x is the slot number of the cable module.
y is the cable interface number, which is 0.
1-4292967295 is the Service Flow Identifier (SFID).
cr is a command return, which displays QoS service flow statistics for all SFIDs.
1-65535 is the classifier identifier.
Implementing Spectrum Management
The spectrum management system monitors the upstream signal integrity, and collects
upstream spectrum information. When signal integrity degrades due to noise, the
spectrum management system automatically configures the upstream channel
parameters to maintain low packet loss by changing the upstream frequency,
modulation profile, channel-width and/or power level to ensure that upstream
performance stays at acceptable levels.
The following tasks are used to implement frequency agility on the BSR:
• Configuring a Spectrum Group
• Applying a Spectrum Group to an Upstream Port
• Evaluating Spectrum Management Performance
Note: If the Classifier ID is not given, all the classifiers with the given SFID
are listed.
