Configuration Commands
Page 216 7710 SR OS Interface Configuration Guide
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 ]}
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 — No port link down dampening is enabled; link down transitions are immediately reported
to upper layer protocols.
up 0 — 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, to notify the upper layers after an interface transitions
from a down state to an up state.
Values
0 — 50
down hold-time down — The delay, in seconds, to notify the upper layers after an interface
transitions from an up state to a down state.
Values
0 — 50
hsmda-scheduler-overrides
Syntax [ no ] hsmda-scheduler-overrides
Context config>port>ethernet
Description
This command enables the context to configure ingress and egress HSMDA scheduler override
parameters. Executing hsmda-scheduler-override places the current CLI context into the egress
scheduler override node either at the ingress MDA or egress port level.
