Purpose
• The default is 1000 ms with a jitter of 50 percent. The
range is from 1000 ms to 5000 sec.
Configures the slow refresh interval for PSC messages.
• The default is 5 sec. The range is from 5 secs to 86400
secs (24 hours).
Configures the remote-event expiration timer.
• By default, this timer is disabled. The remote refresh
interval range is from 5 to 86400 sec (24 hours). The
message count is from 5 to 1000. If you do not specify the
message count value, it is set to 5, which is the default.
Exits MPLS TP global mode.
Creates an MPLS-TP tunnel called number and enters TP
interface tunnel mode.
Enables PSC.
By default, PSC is disabled.
Enables the sending of emLockout on working/protected
transport entities if the lockout command is issued on each
working/protected transport entity respectively. By default, the
sending of emLockout is disabled.
Enters working LSP mode on a TP tunnel interface.
