efc exclude-prefix

Identifies specific prefixes that are not to be automatically probed as a part of a data stream received by the optional EFC module.

efc exclude-prefix <address>[/<mask>]
 
no efc exclude-prefix [ <address> ]
 

• address--IP address (a.b.c.d)
• mask--mask portion of CIDR-formatted prefix address

Must be in active-measurement group configuration mode (config-engine-active), which requires privileged-level access.

Available for use multiple times in the configuration.

None

Use the efc exclude-prefix command to identify prefixes that are not to be probed as a part of a data stream received by the optional EFC module.

If the /mask portion of the address is not specified, the address is assumed to be a /32 prefix (a single host).

The efc exclude-prefix command is one of several commands which place restrictions on which endpoints obtained from the EFC module will be probed. See also:

• efc bytes minimum
• efc bytes top
• efc last-update-within
• efc source

You can use them together in the same active measurement group.

Use the no form of the command without an address to remove all prefix exclusions from the active-measurement group configuration block.

Use the no form of the command with an address to remove a specific exclusion from the active-measurement group configuration block.
