Port Connections and Configuration: All port trunk links must be point- to-point connections between the Series 5300XL Switches and another switch, router, server, or workstation configured for port trunking. No intervening, non-trunking devices are allowed. It is important to note that ports on both ends of a port trunk group must have the same mode (speed and duplex) and flow control settings.

Link Connections. The switch does not support port trunking through an intermediate, non-trunking device such as a hub, or using more than one media type in a port trunk group. Similarly, all links in the same trunk group must have the same speed, duplex, and flow control.

Port Security Restriction. Port security does not operate on a trunk group. If you configure port security on one or more ports that are later added to a trunk group, the switch will reset the port security parameters for those ports to the factory-default configuration.

To avoid broadcast storms or loops in your network while configuring a trunk, first disable or disconnect all ports you want to add to or remove from the trunk. After you finish configuring the trunk, enable or re-connect the ports.

Series 5300XL Switches Port Trunk Features and Operation

The Series 5300XL Switches offers these options for port trunking:

�LACP (IEEE 802.3ad—page 9-25)

�Trunk (non-protocol—page 9-30)

�FEC (Fast EtherChannel®—page 9-30)

The switch supports 36 trunk groups of up to four ports each. (Using the Link Aggregation Control Protocol—LACP—option, you can include standby trunked ports in addition to the maximum of four actively trunking ports.)
