Using the SEHI Hub View
•Blue indicates that the port has been disabled through management.
•Yellow indicates that the port is enabled but does not currently have a valid connection. This usually indicates that the device at the other end of the segment is turned off.
•Red indicates that the port is enabled, but is not able to pass packets. This generally means that the port has been segmented by management after experiencing an excessive number of collisions; for a BNC (thin coax) port, however, this may only mean that no cable or terminator has been connected.
When the Admin Status port display option is active, only two colors apply: a port will be displayed in green if it is enabled by management, regardless of whether or not there is a cable attached or a valid link signal detected; a port disabled by management will display as blue.
