Viewing port status and configuring port parameters
Connecting transceivers to fixed-configuration devices
If the switch either fails to show a link between an installed transceiver and another device or demonstrates errors
or other unexpected behavior on the link, check the port configuration on both devices for a speed and/or duplex
(mode) mismatch.
• To check the mode setting for a port on the switch, use either the Port Status screen in the menu interface or
show interfaces brief in the CLI (see Viewing port status and configuration (CLI)).
• To display information about the transceivers installed on a switch, enter the show tech receivers
command in the CLI (The show tech transceivers command on page 76).
