Ethernet Port Commands
Default
null
Parameters
dot1q — Ingress frames carry 802.1Q tags where each tag signifies a different service.
null — Ingress frames will not use any tags to delineate a service. As a result, only one service can be
configured on a port with a null encapsulation type.
qinq — Specifies QinQ encapsulation.
hold-time
Syntax hold-time {[up hold-time up] [down hold-time down] [seconds | centiseconds]}
no hold-time
Context config>port>ethernet
Description
This command configures port link dampening timers which reduce the number of link transitions reported
to upper layer protocols. The hold-time value is used to dampen interface transitions.
When an interface transitions from an up state to a down state, it is immediately advertised to the rest of the
system if the hold-time down interval is zero, but if the hold-time down interval is greater than zero,
interface down transitions are not advertised to upper layers until the hold-time down interval has expired.
Likewise, an interface is immediately advertised as up to the rest of the system if the hold-time up interval is
zero, but if the hold-time up interval is greater than zero, up transitions are not advertised until the hold-time
up interval has expired.
The no form of this command reverts to the default values.
Default
down 0 seconds — No port link down dampening is enabled; link down transitions are immediately reported
to upper layer protocols.
up 0 seconds — No port link up dampening is enabled; link up transitions are immediately reported to upper
layer protocols.
Parameters up hold-time up — — The delay, in seconds or centiseconds, to notify the upper layers after an interface
transitions from a down state to an up state.
Values
down hold-time down — The delay, in seconds or centiseconds, to notify the upper layers after an interface
transitions from an up state to a down state.
Values
seconds | centiseconds — Specify the units of your hold time in seconds or centiseconds.
