Port Connections and Configuration

All port trunk links must be point-to-point connections between the switch
and a router, server, workstation, or another switch 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 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.
C a u t i o n
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 configure the trunk, enable or re-connect the ports.

Port Trunk Options and Operation

The switch offers these options for port trunking:
■
■
The ProCurve 2610-24 switch supports twelve trunk groups of up to eight ports
each. The ProCurve 2610-48 supports twenty-four trunk groups of up to eight
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.)
The multiple physical links in a trunk behave as one logical link
