Column Meaning
Drop Drop a packet upon arrival. This is useful for emulating access control list operation using
DiServ, especially when DiServ and ACL (Access Control List) cannot co-exist on the
same interface.
Exceed Action The action taken on trac that exceeds settings that the network administrator specifies.
Exceed Color Mode The current setting for the color of exceeding trac that you can optionally specify.
Mark CoS The class of service value that is set in the 802.1p header of inbound packets. This is not
displayed if the mark cos was not specified.
Mark CoS as
Secondary CoS
The secondary 802.1p priority value (second/inner VLAN tag. Same as CoS (802.1p)
marking, but the dot1p value used for remarking is picked from the dot1p value in the
secondary (that is, inner) tag of a double-tagged packet.
Mark IP DSCP The mark/re-mark value used as the DSCP for trac matching this class. This is not
displayed if mark ip description is not specified.
Mark IP Precedence The mark/re-mark value used as the IP Precedence for trac matching this class. This is
not displayed if mark ip precedence is not specified.
Non-Conform Action The current setting for the action taken on a packet considered to not conform to the
policing parameters. This is not displayed if policing not in use for the class under this
policy.
Non-Conform COS The CoS mark value if the non-conform action is set-cos-transmit.
Non-Conform DSCP
Value
The DSCP mark value if the non-conform action is set-dscp-transmit.
Non-Conform IP
Precedence Value
The IP Precedence mark value if the non-conform action is set-prec-transmit.
Peak Rate Guarantees a committed rate for transmission, but also transmits excess trac bursts up
to a user-specified peak rate, with the understanding that a downstream network element
(such as the next hop’s policer) might drop this excess trac. Trac is held in queue until
it is transmitted or dropped (per type of queue depth management.) Peak rate shaping
can be configured for the outgoing transmission stream for an AF (Assured Forwarding)
trac class (although average rate shaping could also be used.)
Peak Burst Size (PBS). The network administrator can set the PBS as a means to limit the damage
expedited forwarding trac could inflict on other trac (for example, a token bucket rate
limiter) Trac that exceeds this limit is discarded.
Policing Style The style of policing, if any, used (simple).
If the Policy Name is not specified this command displays a list of all defined DiServ policies. The
following fields are displayed:
Column
Meaning
Policy Name The name of this policy. (The order in which the policies are displayed is not necessarily the same
order in which they were created.)
Policy Type The policy type (Only inbound is supported).
Class Members List of all class names associated with this policy.
The following example shows CLI display output including the mark-cos-as-sec-cos option specified in
the policy action.
