create cfm segment destination

create cfm segment segment_name destination mac_addr {copy segment_name_to_copy}

Description

Creates a CFM segment.

Syntax Description

segment_name

An alpha numeric string identifying the segment name.

mac_addr

Specifies the MAC address.

segment_name_to_copy

Specifies the CFM segment whose configuration is to be copied.

Default

N/A.

Usage Guidelines

Use this command to explicitly create a CFM segment where the segment name is a 32-byte long alpha-numeric character string.

Example

The following command creates a CFM segment named segment-new using MAC address 00:11:22:11:33:11 and copying segment-old:

create cfm segment segment-new destination 00:11:22:11:33:11 copy segment-old
Here, the copy existing cfm segment is an optional parameter, and if used, the following configurations from the existing CFM segment are copied to the newly created segment:
  • DMM transmission interval

  • Class of service

  • Threshold values

  • Measurement window size

  • Timeout value
    Note

    Note

    The copy option is not shown in "show config" as it is used only for copying the existing values when creating a segment.

If you later configure any of the above mentioned information in segment-new, the old value(s) which were copied from segment-old will be overwritten with the new one in segment-new, as is done for any other commands. The same will not be true on the reverse case. If you modify the values of segment-old, the modified value will NOT be propagated to the CFM segments which use segment-old's configurations. In other words, the configurations of segment-old that are at the time of creating segment-new will alone be copied and not any other changes that are made to segment-old later on.
