1.3.4 Configuring the Trouble Notification From Remote OAM Entity

You can configure an error-disable action on an interface. The local interface will
enter the errdisabled state in the following cases:
1.The high threshold of a normal link event on a local interface is exceeded.
2. The remote interface which connects the local interface enters the errdisabled
state.
3. The OAM function on the remote interface which connects the local interface is
shut down by the administrator. The procedure to configure the remote OAM
trouble indication on an interface is shown in the following table:

action
window size of the round-query period. Its unit is
second. It ranges between 10 and 900 and its
default value is 60.
Sets the high and low thresholds of the error CRC
frame event, which triggers the link events of CRC
checksum error.
The threshold high parameter is used to configure
the high threshold. Its unit is signal number. It
ranges between 1 and 65535 and its default value
is none.
The threshold high parameter is used to configure
the low threshold. Its unit is signal number. It ranges
between 0 and 65535 and its default value is 1.
The window parameter is used to configure the
window size of the round-query period. Its unit is
second. It ranges between 1 and 180 and its default
value is 10.
Enables the local link monitoring. When the link
monitoring function is supported, the local link
monitoring is automatically enabled.
Purpose
Enters the global configuration mode.
Enters the interface configuration mode.
Configures the trigger action of a remote OAM
trouble on an interface:
l
The critical-event parameter is used to
enable an interface to enter the errdisabled
state when an undesignated critical event
occurs.
l
The dying-gasp parameter is used to enable
the local interface to enter the errdisabled
state if the high threshold of a normal link
event on a local interface is exceeded or if the
remote interface which connects the local
interface enters the errdisabled state or if the
OAM function on the remote interface which
