Policy-Map Rename; Randomdrop - Planet Networking & Communication WGS3-2820 User Manual

Note The policy type dictates which of the individual policy attribute commands are valid within the policy definition.
:
The CLI mode is changed to Policy-Map Config when this command is successfully executed.

Mode Global Config
9.5.11.1 no policy-map
This command eliminates an existing DiffServ policy. The <policyname> parameter is the name of an existing DiffServ policy.
This command may be issued at any time; if the policy is currently referenced by one or more interface service attachments, this
deletion attempt shall fail.
▫
Format no policy-map <policyname>
▫
Mode Global Config

9.5.12 policy-map rename

This command changes the name of a DiffServ policy. The <policyname> is the name of an existing DiffServ class. The
<newpolicyname> parameter is a case-sensitive alphanumeric string from 1 to 31 characters uniquely identifying the policy.

Format policy-map rename <policyname> <newpolicyname>

9.5.13 randomdrop

This command changes the active queue depth management scheme from the default tail drop to RED. The first two data
parameters are the average queue depth minimum and maximum threshold values specified in bytes. The minimum threshold
is an integer from 1 to 250000. The maximum threshold is an integer from 1 to 500000, but it must be equal to or greater than
the minimum threshold. The third data parameter is the maximum drop probability and is an integer from 0 to 100. It indicates
the percentage likelihood that a packet will be dropped when the average queue depth reaches the maximum threshold value.
The remaining parameters are all optional. The fourth data parameter is the sampling rate, indicating the period at which the
queue is sampled for computing the average depth. Expressed in microseconds, the sampling rate is an integer from 0 to
1000000, with a default of 0 (meaning per-packet sampling). The last parameter is the decay exponent, which determines how
quickly the average queue length calculation decays over time, with a higher number producing a faster rate of decay. This
value is an integer from 0 to 16, with a default of 9.
Note The last two parameters, namely sampling rate and decay exponent, are hierarchically specified in this command.
:
That is, in order to provide a value for the decay exponent <0-16>, the user is required to also specify a sampling rate
<0-1000000> for proper command interpretation.
