SPEED
Mode Interface Configuration
Default By default, ports autonegotiate speed (except for 100Base-FX ports which do not
support auto-negotiation, so default to 100 Mbps).
Usage notes We recommend having autonegotiation enabled for link speeds of 1000 Mbps and
above. For example, to apply a fixed speed of 1000 Mbps use the command speed
auto 1000.
If multiple speeds are specified after the auto option to autonegotiate speeds, then
the device only attempts autonegotiation at those specified speeds.
Switch ports in a static or dynamic (LACP) channel group must have the same port
speed and be in full duplex mode. Once switch ports have been aggregated into a
channel group, you can set the speed of all the switch ports in the channel group
by applying this command to the channel group.
