Configuration Commands
Page 420 7750 SR OS Interface Configuration Guide
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 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 0 — 2000
lacp
Syntax lacp [mode] [administrative-key admin-key]
no lacp
Context config>lag
Description This command specifies the LACP mode for aggregated Ethernet interfaces only. This command
enables the LACP protocol. Per the IEEE 802.3ax standard (formerly 802.3ad), 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. LACP
can be enabled on a maximum of 256 ports.
Default no lacp
Parameters mode — Specifies the mode in which LACP will operate.
Values passive — Starts transmitting LACP packets only after receiving packets.
active — Initiates the transmission of LACP packets.
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. If it is not specified, a random key is assigned.
Values 1 — 65535
