hold-time
Syntax hold-time hold-time {[up hold-time up] [down hold-time down]}
no hold-time
Context config>port>tdm
Description This command configures link dampening timers in 100s of milliseconds. This guards against reporting
excessive interface transitions. This is implemented by not advertising subsequent transitions of the inter-
face to upper layer protocols until the configured timer has expired.
Default no hold-time
Parameters up hold-time up — Configures the hold-timer for link up event dampening. A value of zero (0) indicates
that an up transition is reported immediately.
Values
down hold-time down — The hold-timer for link down event dampening. A value of zero (0) indicates that
a down transition is reported immediately.
Values
This command is only supported on the m4-chds3-as, m12-chds3-as, and c4-ds3 MDAs.
lbo
Syntax lbo [0dB | -7.5dB | -15.0dB | -22.5dB]
Context config>port>tdm
Description This command applies only to a DS-1 port configured with a 'long' buildout (see the buildout command).
Specify the number of decibels the transmission signal decreases over the line.
For 'short' buildout the following values are valid:
lboNotApplicable — Not applicable
For 'long' buildout the following values are valid:
lbo0dB
lboNeg7p5dB
lboNeg15p0dB
lboNeg22p5dB
The default for 'short' build out is 'NotApplicable' while the default for 'long' buildout is 'lbo0dB'.
length
Syntax length {133 | 266 | 399 | 533 | 655}
