map-group

Required Command-Line Mode = Configure

Use the map-group command to create a group of maps for GTP forward listing and GTP flow sampling. All the maps in a map group receive traffic according to map rules, rather than map priority. Thus, multiple copies of a GTP packet can be sent to more than one tool. This functionality is referred to as overlapping maps.

On the virtual port, a mode of gtp-overlap must be specified. Refer to vport.

The map-group command has the following syntax:

map-group alias <alias>
   comment <comment>
   map-list <list of maps>

The following table describes the arguments for the map-group command:

Argument

Description

alias <alias>

Specifies the name of the map group. The alias must be unique and can contain up to 128 characters. Aliases are case-sensitive.

For example:

(config) # map-group alias mg1

comment <comment>

Specifies a unique text string that describes the map group. Comments can be up to 128 characters. Comments longer than one word must be enclosed in double quotation marks.

For example:

(config) # map-group alias mg1 comment “Shared collector”

map-list <list of maps>

Specifies the maps in a list separated by commas.

For example:

(config) # map-group alias mg1 map-list lev2_fs1_4,lev2_fs2_4,lev2_fs3_4

NOTES:

A map group can be associated with only one GigaSMART group (gsgroup).
All maps in the map list have to be associated with the same gsgroup.
All maps within a map group must be connected to the same vport.
A map group can consist of only one GTP forward listing map or only one GTP flow sampling map but it cannot contain two maps of the same type.
Once a map group is created, it cannot be edited to change the type or subtype of the map. However, you can add and edit the map rules for a map while it is configured in a map group.
If multiple map groups are configured, the maps within each map group must point to the same port groups as the other map groups.
