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 (see "Configuring Remote Maintenance End Points"). 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 (see "Configuring CFM Maintenance Domains").
◆ AIS Status – Enables/disables suppression of the Alarm Indication Signal (AIS).
(Default: Enabled)
◆ 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)
