Port Trunking Trunk Configuration Methods Table 11-2. Trunk Configuration Protocols Protocol LACP (802.3ad) Trunking Options Provides dynamic and static LACP trunking options. • Dynamic LACP - Use the switch-negotiated dynamic LACP trunk when: - The port on the other end of the trunk link is configured for Active or Passive LACP. - You want fault-tolerance for high-availability applications. If you use an eight-link trunk you can also configure one or more additional links to operate as standby links that will activate only if another active link goes down. • Static LACP - Use the manually configured static LACP trunk when: - The port on the other end of the trunk link is configured for a static LACP trunk - You want to configure non-default spanning tree or IGMP parameters on an LACP trunk group. - You want an LACP trunk group to operate in a VLAN other than the default VLAN and GVRP is disabled. (Refer to "VLANs and Dynamic LACP" on page 11-23.) - You want to use a monitor port on the switch to monitor an LACP trunk. For more information, refer to "Trunk Group Operation Using LACP" on page 11-18. Trunk (nonprotocol) Provides manually configured, static-only trunking to: • Most ProCurve switches and routing switches not running the 802.3ad LACP protocol. • Windows NT and HP-UX workstations and servers Use the Trunk option when: - The device to which you want to create a trunk link is using a non-802.3ad trunking protocol - You are unsure which type of trunk to use, or the device to which you want to create a trunk link is using an unknown trunking protocol. - You want to use a monitor port on the switch to monitor traffic on a trunk. Refer to "Trunk Group Operation Using the "Trunk" Option" on page 11-26. 11-6
