Logged-In LED Indications

Logged-In LED Indications

Port diagnostics are indicated by the Logged-In LED for each port as shown in Figure 4-1.

Logged-In LED

Figure 4-1. 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.

Flashing twice per second: The port is down, offline, or an error has occurred.

If a Logged-In LED is flashing twice per second, review the event browser for alarm messages regarding the affected port. You can also inspect the alarm log using the Show Alarm command. If there is an error, alarm messages may point to one or more of the following conditions:

E_Port Isolation

Excessive Port Errors

E_Port Isolation

ALogged-In LED error indication is often the result of E_Port isolation. An isolated E_Port is indicated by a red link in the EFCM BASIC topology display. E_Port isolation can be caused by the following:

Security failure

FL_Port is connected to another switch

Conflicting domain IDs

Conflicting timeout values

Conflicting zone membership between active zone sets

Refer to the EFCM Basic Management Guide for information about how to change domain IDs, timeout values, and edit zoning.

Review the event browser and do the following to diagnose and correct an isolated E_Port:

1.Does the event browser show an alarm about an invalid attach on the affected port?
