Interface Config mode commands
The CLI commands in Interface Config mode used to configure LAGs are:
• Add a port to a LAG:
—
addport unit/slot/port (where unit/slot/port is the logical interface defined by the system for
the LAG)
• Delete ports:
— deleteport unit/slot/port
• Delete one or all LAGs:
— delete interface {unit/slot/port | all}
• Set spanning-tree options on a selected LAG:
—
spanning-tree {edgeport | hello-time | port | mst} (Specify edgeport for fast, no
spanning-tree edgeport for 802.1d.)
Static LAG CLI Management
SFTOS configures dynamic LAGs by default. If you want to convert the LAG to a static LAG, use:
•
protocol static, in Interface Port Channel Config mode.
(
Before v. 2.5.1, the syntax was port-channel staticcapability.)
— All LAGs with configured members but no active members will now aggregate statically
on link UP interfaces.
•
show interface port-channel brief (Privileged Exec mode and User Exec mode) displays whether static
capability is enabled.
Configuring a LAG
The following procedure shows the basic steps for creating and configuring a LAG (Port Channel).
Note: The [no] port lacpmode enable command is deprecated.
Note: By default, dynamic LAGs are created, and link trap notification is enabled.
Note: A LAG (Port Channel) cannot have an IP address.
