Troubleshooting

This chapter contains the following sections:

Collecting System Information

You can get information about your appliance and its status, including your serial number. Refer Monitoring System Status

Troubleshooting Hardware Issues

Lights on the front and/or rear panels of your hardware appliance indicate health and status of your appliance. For descriptions of these indicators, see the hardware guides such as the Cisco x90 Series Content Security Appliances Installation and Maintenance Guide available from the location specified in.

Specifications for your appliance, such as temperature ranges, are also available in these documents.


Note
If you need to cycle power to your x80 or x90 appliance, wait at least 20 minutes for the appliance to come up (all LEDs are green) before pushing the power button.

Troubleshooting Feature Setup Issues

If you are experiencing difficulty configuring a feature successfully, see the summaries of the tasks you must complete for each feature. These include links to specific information for each.

Troubleshooting Performance Issues on Managed Appliances

To identify which parts of the system are using the most resources if you experience performance issues, you can look at the System Capacity reports for all managed appliances (Email or Web Security), and for each managed appliance. For Email Security appliances, seeSystem Capacity Page. For Web Security appliances, seeSystem Capacity Page.

Troubleshooting Issues with Specific Functionality

See alsoTroubleshooting Feature Setup Issues.

Web Security-Related Issues

Email Security-Related Issues

General Issues

  • If you are unable to load a configuration file, make sure your disk space quotas are larger than the current size of each function in the table on the Management Appliance > System Administration > Disk Management page.

  • If you have recently upgraded and the online help appears to be outdated or you cannot find the information about a new feature, clear your browser cache and then reopen the browser window.

  • Unexpected behavior can occur when configuring settings using the web interface if you are using multiple browser windows or tabs simultaneously.

  • SeeResponding to Alerts.

  • SeeTroubleshooting Administrative User Access.

Responding to Alerts

Alert: Battery Relearn Timed Out (RAID Event) on 380 or 680 Hardware

Problem: You receive an alert with subject “Battery Relearn Timed Out” for 380 or 680 hardware.

Solution: This alert may or may not indicate a problem. The battery relearn timeout, in itself, does not mean there is any problem with the RAID controller. The controller can recover in the subsequent relearn. Please monitor your email for any other RAID alerts for the next 48 hours, to ensure that this is not the side-effect of any other problem. If you do not see any other RAID-related alerts from the system, then you can safely ignore this alert.

Working with Technical Support

Opening or Updating a Support Case from the Appliance

    Enabling Remote Access for Cisco Technical Support Personnel

    Only Cisco Customer Assistance can access your appliance using these methods.

    Enabling Remote Access to Appliances With an Internet Connection

    Support accesses the appliance through an SSH tunnel that this procedure creates between the appliance and the upgrades.ironport.com server.

    Before you begin

    Identify a port that can be reached from the internet. The default is port25 which will work in most environment . Connections over this port are allowed in most firewall configurations.

    Procedure
    Step 1

    Log in to the appliance.

    Step 2

    From the top right side of the GUI window, choose Help and Support > Remote Access.

    Step 3

    Click Enable.

    Step 4

    Enter information.

    Step 5

    Click Submit.

    What to do next

    When remote access for support personnel is no longer required, seeDisabling a Tech Support Tunnel.

    Enabling Remote Access to Appliances Without a Direct Internet Connection

    For appliances without a direct internet connection, access is made through a second appliance that is connected to the internet.

    Before you begin
    Procedure
    Step 1

    From the command-line interface of the appliance requiring support, enter the techsupport command.

    Step 2

    Enter sshaccess .

    Step 3

    Follow the prompts.

    What to do next

    When remote access for support personnel is no longer required, see the following:

    Disabling a Tech Support Tunnel

    An enabled techsupport tunnel remains connected to upgrades.ironport.com for 7 days. After that time, established connections will not be disconnected but will be unable to re-attach to the tunnel once disconnected.

    Procedure
    Step 1

    Log in to the appliance.

    Step 2

    From the top right side of the GUI window, choose Help and Support > Remote Access.

    Step 3

    Click Disable.

    Disabling Remote Access

    A remote access account that you create using the techsupport command remains active until you deactivate it.

    Procedure
    Step 1

    From the command-line interface, enter the techsupport command.

    Step 2

    Enter sshaccess .

    Step 3

    Enter disable .

    Checking the Status of the Support Connection

    Procedure
    Step 1

    From the command-line interface, enter the techsupport command.

    Step 2

    Enter status .

    Running a Packet Capture

    Packet Capture allows support personnel to see the TCP/IP data and other packets going into and out of the appliance. This allows Support to debug the network setup and to discover what network traffic is reaching the appliance or leaving the appliance.

    Procedure

    Step 1

    Choose Help and Support > Packet Capture.

    Step 2

    Specify packet capture settings:

    1. In the Packet Capture Settings section, click Edit Settings.

    2. (Optional) Enter duration, limits, and filters for the packet capture.

      Your Support representative may give you guidance on these settings.

      If you enter a capture duration without specifying a unit of time, AsyncOS uses seconds by default.

      In the Filters section:

      • Custom filters can use any syntax supported by the Unix tcpdump command, such as host 10.10.10.10 && port 80 .
      • The client IP is the IP address of the machine connecting to the appliance, such as a mail client sending messages through the Email Security appliance.
      • The server IP is the IP address of the machine to which the appliance is connecting, such as an Exchange server to which the appliance is delivering messages.

      You can use the client and server IP addresses to track traffic between a specific client and a specific server, with the Email Security appliance in the middle.

    3. Click Submit.

    Step 3

    Click Start Capture.

    • Only one capture may be running at a time.
    • When a packet capture is running, the Packet Capture page shows the status of the capture in progress by showing the current statistics, such as file size and time elapsed.
    • The GUI only displays packet captures started in the GUI, not from the CLI. Similarly, the CLI only displays the status of a current packet capture run started in the CLI.
    • The packet capture file is split into ten parts. If the file reaches the maximum size limit before the packet capture ends, the oldest part of the file is deleted (the data is discarded) and a new part starts with the current packet capture data. Only 1/10 of the packet capture file is discarded at a time.
    • A running capture started in the GUI is preserved between sessions. (A running capture started in the CLI stops when the session ends.)
    Step 4

    Allow the capture to run for the specified duration, or, if you have let the capture run indefinitely, manually stop the capture by clicking Stop Capture.

    Step 5

    Access the packet capture file:

    • Click the file in the Manage Packet Capture Files list and click Download File.
    • Use FTP or SCP to access the file in the captures subdirectory on the appliance.

    What to do next

    Make the file available to Support:

    Remotely Resetting Appliance Power

    If the appliance requires a hard reset, you can reboot the appliance chassis remotely using a third-party Intelligent Platform Management Interface (IPMI) tool.

    Restrictions

    • Remote power cycling is available only on certain hardware.

      For specifics, seeEnabling Remote Power Cycling.

    • If you want be able to use this feature, you must enable it in advance.

      For details, seeEnabling Remote Power Cycling.

    • Only the following IPMI commands are supported:

      status, on, off, cycle, reset, diag, soft

      Issuing unsupported commands will produce an “insufficient privileges” error.

    Before you begin

    • Obtain and set up a utility that can manage devices using IPMI version 2.0.
    • Understand how to use the supported IPMI commands. See the documentation for your IPMI tool.

    Procedure

    Step 1

    Use IPMI to issue a supported power-cycling command to the IP address assigned to the Remote Power Cycle port, which you configured earlier, along with the required credentials.

    For example, from a UNIX-type machine with IPMI support, you might issue the command:

    ipmitool -I lan -H 192.0.2.1 -U remoteresetuser -P password chassis power reset

    where 192.0.2.1 is the IP address assigned to the Remote Power Cycle port and remoteresetuser and password are the credentials that you entered while enabling this feature.

    Step 2

    Wait at least eleven minutes for the appliance to reboot.
