Default Port Operation
In the default configuration, all ports are configured for passive LACP. How-
ever, if LACP is not configured, the port will not try to detect a trunk config-
uration and will operate as a standard, untrunked port. The following table
describes the elements of per-port LACP operation. To display this data for a
particular switch, execute the following command in the CLI:
SMC TigerSwitch 10/100 > show lacp
Table 6-7. LACP Port Status Data
Static LACP The trunk operates if the trunk group on the opposite device is running one of the following trunking
protocols:
• Active LACP
• Passive LACP
• Trunk
• FEC
This option uses
Trk1 for the port Group parameter and LACP for the port Type parameter.
Displaying Static LACP Trunk Data: To list the configuration and status for a static LACP trunk, use the
CLI
show lacp command. To list a static LACP trunk with its assigned ports, use the CLI show trunk
command or display the menu interface Port/Trunk Settings screen.
Static LACP does not allow standby ports.
LACP Port Trunk
Configuration Operation
Status Name Meaning
Port Numb Shows the physical port number for each port configured for LACP operation (1, 2, 3 . . .). Unlisted port
numbers indicate that the missing ports are assigned to a static Trunk group, an FEC trunk group, or are
not configured for any trunking.
LACP Enabled Active: The port automatically sends LACP protocol packets.
Passive: The port does not automatically send LACP protocol packets, and responds only if it receives
LACP protocol packets from the opposite device.
A link having either two active LACP ports or one active port and one passive port can perform dynamic
LACP trunking. A link having two passive LACP ports will not perform LACP trunking because both ports
are waiting for an LACP protocol packet from the opposite device.
Note: In the default switch configuration, all ports are configured for passive LACP operation.
Trunk Group Trk1: This port has been manually configured into a static LACP trunk.
Trunk Group Same as Port Number: The port is configured for LACP, but is not a member of a port trunk.
