Command History
Usage Guidelines To optimize the port for a host connection, the switchport host command sets switch port mode to
access, enables spanning tree Port Fast, and disables channel grouping. Only an end station can accept
this configuration.
Because spanning tree Port Fast is enabled, you should enter the switchport host command only on ports
that are connected to a single host. Connecting other switches, hubs, concentrators, or bridges to a
fast-start port can cause temporary spanning-tree loops.
Enable the switchport host command to decrease the time that it takes to start up packet forwarding.
Examples This example shows how to optimize the port configuration for a host connection:
Switch(config-if)# switchport host
switchport mode will be set to access
spanning-tree portfast will be enabled
channel group will be disabled
Switch(config-if)#
You can verify your setting by entering the show interfaces interface-id switchport privileged EXEC
command.
