Monitor Link group view
Parameter
interface-type: Port type.
interface-number: Port number.
uplink: Configures the specified port as the uplink port of the Monitor Link group
downlink: Configures the specified port as the downlink port of the Monitor Link group
Description
Use the port command to configure the specified port as a member of the Monitor Link group.
Use the undo port command to remove the specified port from the current Monitor Link group.
In Monitor Link, a Monitor Link group member can be a single port, a static link aggregation group, but
not a dynamic link aggregation group. The uplink port of a Monitor Link group can also be a Smart Link
group.
Do not use this command on member ports of a link aggregation group or a Smart Link group.
A port or a link aggregation group cannot serve as a member port for two Smart Link groups. On the
other hand, a port or a link aggregation group cannot serve as a member for a Smart Link group and a
Monitor Link group at the same time. However, a Smart Link group can serve as the uplink member port
of a Monitor Link group.
