Port trunk features and operation

The switches covered in this guide offer these options for port trunking:

Up to 60 trunk groups are supported on the switches. The actual maximum depends on the number of ports available on the switch and the number of links in each trunk. (Using the link aggregation control protocol—LACP—option, you can include standby trunked ports in addition to the maximum of eight actively trunking ports.) The trunks do not have to be the same size; For example, 100 two-port trunks and 11 eight-port trunks are supported.

NOTE:

LACP requires full-duplex (FDx) links of the same media type (10/100Base-T, 100FX, and so on) and the same speed, and enforces speed and duplex conformance across a trunk group. For most installations, Hewlett Packard Enterprise Switch recommends that you leave the port Mode settings at Auto (the default). LACP also operates with Auto-10, Auto-100, and Auto-1000 (if negotiation selects FDx), and 10FDx, 100FDx, and 1000FDx settings. (The 10-gigabit ports available for some switch models allow only the Auto setting.)
