Logged-in LED indications Port diagnostics are indicated by the Logged-in LED for each port (Figure 15). 1 2 1 Logged-in LED (port 0) 2 Logged-in LED (port 10) Figure 15 Logged-in LED The Logged-in LED has three indications: • Continuous illumination: A device is logged in to the port. • Flashing once per second: A device is logging in to the port, or the port is in the diagnostics state. • Flashing twice per second: The port is down, offline, or an error has occurred. If a Logged-in LED is flashing two times per second, review the event browser for alarm messages regarding the affected port. You can also inspect the alarm log using the command line interface, show alarm command. If there is an error, alarm messages may point to one or more of the following conditions: • E_Port isolation, page 44 • Excessive port errors, page 45 E_Port isolation A Logged-in LED error indication is often the result of E_Port isolation. E_Port isolation can be caused by the following: • Security failure • A port configured as an F_Port or an FL_Port is connected to another switch • Conflicting domain IDs • Conflicting timeout values • Conflicting zone membership between active zone sets Using QuickTools, review the event browser, and perform the following procedure to diagnose and correct an isolated E_Port: 1. Does the QuickTools event browser show an alarm about an invalid attach on the affected port? • Yes-If you have configured device security, review the ISL group in the active security set to ensure that the membership includes the necessary ports and that the secrets on all switches are correct. • No-Continue. 2. Does the QuickTools event browser show a repeating alarm about an unsupported E_Port command on the affected port? • Yes-The port is configured as an FL_Port and connected to another switch. Correct the port connection or the port type. • No-Continue. 44
