policy-map rename
This command changes the name of a DiffServ policy.
policy-map rename policyname newpolicyname
Syntax
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.
Mode Global Config
mark secondary-cos
This command marks all packets for the associated traffic stream with the specified secondary class of
service value (the inner 802.1Q tag of a double VLAN tagged packet) in the priority field of the 802.1p
header. If the packet does not already contain this header, one is inserted. The CoS value is an integer
from 0 to 7.
mark secondary-cos <0-7>
Syntax
Mode
Policy-Class-Map Config
redirect
This command specifies that all incoming packets for the associated traffic stream are redirected to a
specific egress interface (physical port or port channel).
redirect unit/slot/port
Syntax
Mode Policy Class (The prompt is "(Policy-classmap Config)#".)
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.
