R3303-HP HSR6800 Routers Interface Command Reference

167
You can use the display interface serial interface-number:0 command to check the DSU mode setting,
the subrate, the actual rate, and the baudrate of a CT3 interface. The actual rate does not count in the
overhead bits, and the baudrate is the actual T3 line rate (44736 kbps), with the overhead bits counted
in.
Examples
# Configure T3 2/0/0 interface to operate in the FT3 mode, setting the DSU mode to 1 and the subrate
to 3000 kbps.
<Sysname> system-view
[Sysname] controller t3 2/0/0
[Sysname-T3 2/0/0] using t3
[Sysname-T3 2/0/0] ft3 dsu-mode 1
[Sysname-T3 2/0/0] ft3 subrate 3000
link-delay
Use link-delay to set the physical link state change suppression interval on an interface.
Use undo link-delay to restore the default.
Syntax
link-delay delay-time
undo link-delay
Default
Physical link state change suppression is disabled on an interface.
Views
CT3 interface view
Default command level
2: System level
Parameters
delay-time: Sets the physical link state change suppression interval in the range of 0 to 10 seconds. The
default is 0 seconds.
Usage guidelines
This command prevents frequent link state changes on an interface from affecting ongoing services.
Examples
# Set the physical link state change suppression interval of interface T3 2/0/0 to 8 seconds.
<Sysname> system-view
[Sysname] controller t3 2/0/0
[Sysname-T3 2/0/0] link-delay 8
loopback (CT3 interface)
Use loopback to configure the loopback mode for a CT3 interface.
Use undo loopback to disable loopback.
