CAUTION: Use this command only if you know that the automatic setting does not
match the setting on the remote device. Otherwise, the remote device might send
an unexpected value, and the router might lose data.
path shutdown
path snmp trap link-status
path trigger alarm prdi
Use to overwrite the automatic setting for the path signal label (C2) byte.
By default, the value of the C2 byte for the path is determined by the layers
configured above the SONET/SDH interface and set automatically. The E Series
router sets this default value in accordance with RFC 2558. (See "References"
on page 84.)
Do not specify a path identifier for unchannelized SONET/SDH interfaces.
Example
host1(config-controll)#path overhead c2 20
Use the no version to restore the default setting, in which the value of the C2
byte is determined by the layers configured above the SONET/SDH interface.
See path overhead c2.
Use to disable a path.
Paths are enabled by default.
Example
host1(config-controll)#path shutdown
Use the no version to restart a disabled path.
See path shutdown.
Use to enable SNMP link-status processing for the path layer of the interface.
The default is disabled.
Do not specify a path identifier for unchannelized SONET/SDH interfaces.
Example
host1(config-controll)#path snmp trap link-status
Use the no version to disable SNMP link status processing.
See path snmp trap link-status.
