The
text
argument specifies the description that you want to provide. Enter an
unquoted text string with a maximum of 240 alphanumeric characters.
For example, to specify a description that the policy map is to filter network traffic
to a VIP, enter:
host1/Admin(config-pmap)#
description filter traffic matching a VIP
To remove the description from the class map, enter:
host1/Admin(config-pmap)#
no description
Specifying a Layer 3 and Layer 4 Traffic Class With the Traffic
Policy
To specify a Layer 3 and Layer 4 traffic class created with the
class-map
command to associate network traffic with the traffic policy, use the
class
command in policy map configuration mode.
The syntax of this command is:
class
map_name
The map_name
argument specifies the name of a previously defined Layer 3 and
Layer 4 traffic class, configured with the
class-map
command, to associate traffic
to the traffic policy. Enter an unquoted text string with no spaces and a maximum
of 64 alphanumeric characters.
When you use this command, you will access policy map class configuration
mode.
For example, to specify an existing class map within the Layer 3 and Layer 4
policy map, enter:
host1/Admin(config-pmap)#
class L4_SLB_VIP_CLASS
host1/Admin(config-pmap-c)#
To remove a class map from a Layer 3 and Layer 4 policy map, enter:
host1/Admin(config-pmap)#
no class L4_SLB_VIP_CLASS
To manually insert the class map ahead of a previously specified class map, use
the
class
command with the
insert-before
keyword. However, the ACE does not
save this reordering as part of the configuration.
