Port Trunking Trunk Group Operation Using LACP Default Port Operation In the defaul t configurat ion, LACP is disabled for al l ports. If LACP is not configured as Active on at least one end of a link, then the p ort does not tr y to detect a trunk conf iguration and operates as a standard, unt runked port.
Port Trunking Trunk Group Operation Using LACP LACP Partner Ye s : LACP is enabled on both ends of the link. Status Name Meaning No: LACP is enabled on the switch , but either LACP is not enabled or the link has not been detected on the opposite device.
Port Trunking Trunk Group Operation Using LACP The switch will not allo w you to configure LACP on a port on which port security is enabled. For example: ProCurve(config)# int a17 lacp passive Error configuring port A17: LACP and port security cannot be run together.
Port Trunking Trunk Group Operation Using LACP Blocked Ports w ith Older Devices. Some older devices are limited to four ports in a trunk. When eight LACP-enabl ed ports are connected to one of these older devices, four p orts connect, but t he other four po rts are blocked.
Port Trunking Trunk Group Operation Using LACP ■ If there are ports that you do not want on the default VLAN, ensu re that they cannot become dynamic LACP trunk members.
Port Trunking Trunk Group Operation Using the “Trunk” Option Dynamic/Static LACP Interoperation: A port configured for d ynamic LACP can properly i nteroperate with a port config ured for static (T rk X ) LACP , but any ports configured as stand by LACP links will be ignored.
