4.8.7.6 MA Details
Device Management > CFM > MA Details page is used to configure details of specify MA. Configuring Detailed Settings for a
Maintenance Association
MD Index Domain index. (Range: 1-65535)
MA Index MA identifier. (Range: 1-2147483647)
MA Name Format Specifies the name format for the maintenance association as IEEE 802.1ag character based, or
ITU-T SG13/SG15 Y.1731 defined ICC-based format.
Character String IEEE 802.1ag defined character string format. This is an IETF RFC 2579 DisplayString.
ICC Based ITU-T SG13/SG15 Y.1731 defined ICC based format.
Interval Level The delay between sending CCMs. The setting for this parameter is expressed as levels 4 through 7,
which in turn map to specific intervals of time. (Options: 4 - 100 ms, 5 - 1 sec, 6 - 10 sec, 7 - 60 sec)
Connectivity Check Enables transmission of CCMs. (Default: Disabled)
Cross Check Enables cross-checking between a static list of MEPs assigned to other devices within the same
maintenance association and the MEPs learned through CCMs. Before starting the cross-check process, first configure
the remote MEPs that exist on other devices inside the maintenance association using the Remote MEP List. These
remote MEPs are used in the cross-check operation to verify that all endpoints in the specified MA are operational. The
cross-check start delay, which sets the maximum delay this device waits for a remote MEP to come up before starting the
cross-check operation, is a domain-level parameter. To set this parameter, use the CFM MD Configuration screen.
AIS Status Enables/disables suppression of the Alarm Indication Signal (AIS). (Default: Disabled)
AIS Period Configures the period at which AIS is sent in an MA. (Range: 1 or 60 seconds; Default: 1 second)
AIS Transmit Level Configure the AIS maintenance level in an MA. (Range: 0-7; Default is 0) AIS Level must follow this
rule: AIS Level >= Domain Level
AIS Suppress Alarm Enables/disables suppression of the AIS. (Default: Disabled)
