Link-Delay - HP 6600 Command Reference Manual

Usage guidelines
FT3 (Fractional T3 or Subrate T3) mode is a non-standard E3 application mode. In this mode, the subrate
level setting varies with vendors. You can use the ft3 command to make the device to be compatible with
devices of other vendors operating in specific FT3 DSU modes.
This command is only applicable to CT3 boards that support FT3.
This command is only available in CT3 mode.
As for the ft3 subrate command, the actual subrate usually is not exactly the one set by the command.
After you set the subrate by using the ft3 subrate command, the T3 interface searches the subrate levels
corresponding to the DSU mode it is operating in and selects the one that is closest to that set by the
command as its subrate. The device then adjusts the hardware to allow for the subrate.
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.

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.
