null — Ingress frames will not use any tags to delineate a service. As a result, only one service can be con-
figured on a port with a null encapsulation type.
qinq — Specifies QinQ encapsulation.
hold-time
Syntax hold-time down hold-down-time
no hold-time
Context config>lag
Description
This command specifies the timer, in tenths of seconds, which controls the delay between detecting that a
LAG is down (all active ports are down) and reporting it to the higher levels.
A non-zero value can be configured, for example, when active/standby signalling is used in a 1:1 fashion to
avoid informing higher levels during the small time interval between detecting that the LAG is down and the
time needed to activate the standby link.
Default 0
Parameters
down hold-down-time — Specifies the hold-time for event reporting
Values
lacp
Syntax lacp [mode] [administrative-key admin-key] [system-id system-id][system-priority priority]
Context config>lag
Description This command specifies the LACP mode for aggregated Ethernet interfaces only. This command enables the
LACP protocol. Per the IEEE 802.1ax standard, the Link Aggregation Control Protocol (LACP) provides a
standardized means for exchanging information between Partner Systems on a link to allow their Link
Aggregation Control instances to reach agreement on the identity of the Link Aggregation Group to which
the link belongs, move the link to that Link Aggregation Group, and enable its transmission and reception
functions in an orderly manner.
Default no lacp
Parameters
Note: If any of the parameters are omitted, the existing configuration is preserved. The default parameter
values are used if a parameter is never explicitly configured.
mode — Specifies the mode in which LACP will operate.
Values
administrative-key admin-key — Specifies an administrative key value to identify the channel group on
each port configured to use LACP. This value should be configured only in exceptional cases. A random
