Table 12-4. LACP Trunk Types
LACP Port Trunk Operation
Configuration
Dynamic LACP This option automatically establishes an
parameter and DynX for the port Group name, where X is an automatically assigned value from 1 to 12
(ProCurve 2610-24) or 1-24 (ProCurve 2610-48), depending on how many dynamic and static trunks are
currently on the switch. (The ProCurve Switch 2610-24 allow a maximum of twelve trunk groups in any
combination of static and dynamic trunks; the ProCurve switch 2610-48 allows a maximum of twenty-
four trunk groups in any combination of static and dynamic trunks.)
Under the following conditions, the switch automatically establishes a dynamic LACP port trunk group
and assigns a port Group name:
• The ports on both ends of a link have compatible mode settings (speed and duplex).
• The port on one end of a link must be configured for LACP Active and the port on the other end of
the same link must be configured for either LACP Passive (the default) or LACP Active. For example:
Either of the above link configurations allow a dynamic LACP trunk link.
Standby Links: A maximum of eight operating links are allowed in the trunk, but, with dynamic LACP,
you can configure one or more backup links that the switch automatically activates if a primary link
fails. To configure a link as a standby for an existing dynamic LACP trunk, ensure that the ports in the
standby link are configured the same as either of the above examples.
Displaying Dynamic LACP Trunk Data: To list the configuration and status for a dynamic LACP trunk,
use the CLI
Note: The dynamic trunk is automatically created by the switch, and is not listed in the static trunk
listings available in the menu interface or in the CLI show trunk listing.
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

is an automatically assigned value from 1 to 12 (ProCurve 2610-24) or 1-24 (ProCurve 2610-48) depending
on how many static trunks are currently operating on the switch. (The switch allows the maximum
number of trunk groups in any combination of static and dynamic trunks.)
Displaying Static LACP Trunk Data: To list the configuration and status for a static LACP trunk, use the
show lacp
CLI
command or display the menu interface Port/Trunk Settings screen.
Static LACP does not allow standby ports.
