Replacing an AS

Replacing an AS

Context

In an SVF system, each AS is identified by its MAC address by default. When a new device is used to replace an AS, the SVF system considers the new device as a new AS because their MAC addresses are different. As a result, the new AS does not inherit services on the previous AS.

You can enable AS automatic replacement to solve this problem. When an AS is replaced by a new device connected to the same fabric port, the SVF system replaces the AS MAC address with the MAC address of the new device in the configuration. Consequently, the new device can inherit services on the AS.

NOTE:
  • An AS can only be replaced by a device of the same model. If the new device is a different model, the SVF system considers it as a new AS, which then cannot inherit services on the previous AS.

  • Only a standalone AS can be replaced, and a stacked AS cannot be replaced.

  • AS automatic replacement is not supported when an AS connects to the parent through a network.

  • To ensure that a replacement AS can be successfully authenticated, run the auth-mode none command to set the AS authentication mode to none, or run the whitelist mac-address command to add the management MAC address of the replacement AS to the whitelist. If the replacement AS has no management MAC address configured, its system MAC address is used as the management MAC address.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run uni-mng

    The uni-mng view is displayed.

  3. Run as auto-replace enable

    AS automatic replacement is enabled.

  4. Replace the existing AS with a new AS. The two ASs connect to the same fabric port.
