Modifying Port Operating Characteristics
You can make permanent or temporary changes to port operating characteristics.
You make permanent port configuration changes using the Set Config Port
command. These changes are saved in the active configuration and are
preserved across switch or port resets. The Set Port command makes temporary
changes that apply until the next port or switch reset, or until you activate a
configuration.
NOTE:
The Show Media command requires the SANdoctor license key. To
purchase a license key, contact your authorized maintenance provider or
authorized reseller.
NOTE:
8-Gbps SFPs do not support the 1-Gbps setting. Setting a port to 1-Gbps
that has an 8-Gbps SFP will down the port.
