The security certificate has expired or is not yet valid The name on the security certificate is invalid or does not match the name of the site file This page contains both secure and nonsecure items. Do you want to display the nonsecure items? Action The SSL certificate is not installed correctly or HTTPS is not enabled correctly. Make sure that the certificate has not expired, that HTTPS is enabled, and that certificate file names are configured correctly. The certificate is not installed in the browser. Install it as described in the Fabric OS Administrator's Guide. Either the certificate file is corrupted or it needs to be updated. Click View Certificate to verify the certificate content. If it is corrupted or out of date, obtain and install a new certificate. The certificate is not installed correctly in the Java Plug-in. Install it as described in the Fabric OS Administrator's Guide. Click No in this pop-up window. The session opens with a closed lock icon on the lower-right corner of the browser, indicating an encrypted connection. Gathering additional information For security-related issues, use the following guidelines to gather additional data for your switch support provider. ∙ Use the supportSave -n command. ∙ If not sure about the problem area, use the supportSave -n to collect data from all switches in the fabric. ∙ If you think it may be related to E_Port authentication, use the supportSave -n command to collect data from both switches of the affected E_Port. ∙ If you think this is a policy-related issue, FCS switch, or other security server-related issue, then use supportSave -n to collect data from the Primary FCS switch and all affected switches. ∙ If login-related, then also include the following information: - Does login problem appear on a Serial, CP IP, or Switch IP address connection? - Is it CP0 or CP1? - Is the CP in active or standby? - Is it the first time login after firmwareDownload and reboot? SNMP This section describes symptoms with associated causes and recommended actions for SNMP-related issues. Symptom Probable cause and recommended action SNMP management station server is unable to receive traps from fabric. There are several causes related to this generic issue. You must verify the following: ∙ There are no port filters in the firewalls between the fabric and the SNMP management station. ∙ If your SNMP management station is a dual-homed server, check that the routing tables are set up correctly for your network.

SSL messages and actions

Message

Action

The page cannot be displayed

The SSL certificate is not installed correctly or HTTPS is not enabled

correctly. Make sure that the certificate has not expired, that HTTPS is

enabled, and that certificate file names are configured correctly.

The security certificate was issued by a company you have not chosen to

trust.

The certificate is not installed in the browser. Install it as described in the

Fabric OS Administrator's Guide

The security certificate has expired or is not yet valid

Either the certificate file is corrupted or it needs to be updated. Click

View

Certificate

to verify the certificate content. If it is corrupted or out of date,

obtain and install a new certificate.

The name on the security certificate is invalid or does not match the name

of the site file

The certificate is not installed correctly in the Java Plug-in. Install it as

described in the

Fabric OS Administrator's Guide

This page contains both secure and nonsecure items. Do you want to

display the nonsecure items?

Click

in this pop-up window. The session opens with a closed lock

icon on the lower-right corner of the browser, indicating an encrypted

connection.

Gathering additional information

For security-related issues, use the following guidelines to gather additional data for your switch support provider.

∙

Use the

supportSave -n

command.

∙

If not sure about the problem area, use the

supportSave -n

to collect data from all switches in the fabric.

∙

If you think it may be related to E_Port authentication, use the

supportSave -n

command to collect data from both switches of

the affected E_Port.

∙

If you think this is a policy-related issue, FCS switch, or other security server-related issue, then use

supportSave -n

to collect

data from the Primary FCS switch and all affected switches.

∙

If login-related, then also include the following information:

–

Does login problem appear on a Serial, CP IP, or Switch IP address connection?

–

Is it CP0 or CP1?

–

Is the CP in active or standby?

–

Is it the first time login after

firmwareDownload

and reboot?

SNMP

This section describes symptoms with associated causes and recommended actions for SNMP-related issues.

Symptom

SNMP management station server is unable to receive traps from fabric.

Probable cause and recommended action

There are several causes related to this generic issue. You must verify the

following:

∙

There are no port filters in the firewalls between the fabric and

the SNMP management station.

∙

If your SNMP management station is a dual-homed server,

check that the routing tables are set up correctly for your

network.
