Configuring One-key Bypass Parent topic

The following procedure allows you to change the default settings for the One-key Bypass feature. Examples of when to change the parameters can include:
  • Installing a new One-key Bypass card
  • Selecting NICs supporting One-key Bypass for the data interface
  • Changing the default One-key Bypass mode
If you select one of the supported NICs that can perform hardware bypass in the Deployment Wizard, it will be enabled with the AUTO setting. Under the AUTO setting, the IWSVA monitors the critical services and OS kernel for crashes. If it detects an unrecoverable error, it will open the NIC into "fail open" or bypass mode.
Use the show network lanbypass command to check One-key Bypass status on IWSVA.
To display/enable/disable/change the One-key Bypass service on the IWSVA unit:
  1. Login to the CLI interface.
  2. Execute one of the following commands
Command Description 
show network
lanbypass
 Displays the current configuration status of the One-key Bypass function. 
configure network lanbypass on
Always bypasses traffic. After running this command, all traffic will be bypassed by One-key Bypass card.
Administrators may not be able to access the IWSVA device from the network data interface. The system will not adjust the One-key Bypass status at any time.
 
configure network lanbypass off
 Never bypasses traffic. The system will not adjust the One-key Bypass status at any time. 
configure network lanbypass auto
 The system will auto-adjust the One-key Bypass status. For example, when system starts and stops, the bypass will be turned off and turned on. When system is in an abnormal state (such as kernel panic), the bypass will be turned on. After recovery, the bypass will be turned off automatically.
The One-key Bypass card configuration is saved at: /etc/lanbypass.conf. Migration updates the mapping table to import or export the One-key Bypass configuration.
