Switch recovery techniques

Status messages from the switches, and the switch alerts that can appear on the console, are described below. Detailed recovery steps are provided for each situation.

Status messages

Non-standard configuration

This status indicates that the switch was configured by your Websense partner or Websense Technical Support professional in a special way, to accommodate your network.

Typically, no action is required. The switch can operate in a non-standard configuration when properly provisioned.

If you wish to return the switch to its standard configuration, use the CLI command: switch A1 (A2) configure.

If this does not resolve the issue, check the switch firmware version. Switch firmware version must be version 4.1.1.9.

If the issue persists, perform Booting the switch to Dell settings and then Configuring the switch mode.

For additional assistance, please contact your Websense Support professional.

Alert messages

Connection to switch A1 (or A2) failed

1.

Make certain that the switch hardware is fully seated in the chassis, and that the switch lever is latched. The switch indicator LED may be on, even if the switch is not fully seated. This is because the pins connecting the switch hardware into the chassis are of varying lengths, so that they connect in this sequence as you insert the switch: grounding pin; power pin; data lines.

2.	Try to reach the switch via this CLI command: switch A1 (A2) verify.

3.	It is possible that the switch is in the process of rebooting (to clear an error condition). Try again to verify the switch configuration in 5 minutes.

4.

If you still cannot connect from the blade to the switch, or if you must replace a switch with a new switch that was not configured by a Websense team, then these recovery steps are required (can be accomplished with line console, telnet, or Web UI). Your Websense professional can guide you through these steps.

Unplug the network cables.

Perform Booting the switch to Dell settings.

Perform Configuring the switch mode.

Plug in the network cables.

Switch A1 (A2) logon was not successful

1.	You may not have used the current switch password. Verify the current password at your site and enter it again.

2.	To change the password when you do not know the old one, request assistance from your Websense professional:

Unplug the network cables.

Perform Booting the switch to Dell settings.

Perform Configuring the switch mode.

Plug in the network cables.

Installing a new switch

If you must replace a switch with a new one that has not been set up by a Websense team, insert the switch and latch it. Do not cable it. Then follow these steps:

Perform Booting the switch to Dell settings.

Perform Configuring the switch mode.

Plug in the network cables.

Booting the switch to Dell settings

Connect to the line console with a serial cable.

1.	Log on to the CMC and choose I/O Module Overview at the left. Select the appropriate switch and then initiate a Power Cycle, as shown below:

2.	Wait for the Boot Menu to appear on the console, and then choose: 2 - Start Boot Menu

3.	From the list of options that appears, choose: 10 - Restore configuration to factory defaults (delete config files)

4.	Wait for the console prompt to appear: console>

5.	Copy and paste the following configuration commands into the console for switch A2 (all commands also apply to switch A1, but IP address [line 6] for switch A1 is 169.254.253.1):

enable

configure

vlan 4003

exit

interface vlan 4003

ip address 169.254.253.2 255.255.255.0

exit

interface range gigabitethernet 1/0/1-16

switchport mode general

switchport general allowed vlan add 4003 tagged

exit

enable password websense

username root password websense

exit

write

y

exit

6.	Remember to configure the switch mode. (See Configuring the switch mode.)

Configuring the switch mode

1.	Unplug the network cables from the switch, if not already done.

2.	On any blade except blade 16, to configure switch A1: Run the CLI command "switch A1 configure" in Security Blade Manager. This configures switch A1 for use with all X10G blade servers.

3.	On any blade except blade 16, to configure switch A2: Choose a mode for Switch A2 in the Security Blade Manager:

Run the CLI command "switch A2 configure wcg" to configure switch A2 to support failover for proxy interfaces on blade 16. (This disables the N interface, used if Network Agent runs on blade in Slot 16.)

Run "switch A2 configure na" to configure switch A2 with the N interface for Network Agent supported (default setting).

4.	Wait for the switch to finish rebooting, then run "switch A1 (A2) verify" to verify that the configuration is as expected.

5.	Plug in the network cables for appropriate interfaces C/N/P1/P2 on the switch.
