Parameter

Description

Value

Specifies a PSK for encrypting sensitive information between ACs.

The value is a string of 6 to 32 case-sensitive characters without question marks (?) or spaces. For a plaintext PSK, the length must be 48 or 68 bits. If the string is enclosed in double quotation marks (" "), the string can contain spaces.

Usage Guidelines

Usage Scenario

In inter-AC roaming scenarios, ACs may need to exchange sensitive information such as the user name and password. The PSK is required to protect data transmitted between the ACs.

Precautions

NOTE:

The PSK must be set to the same on ACs. Otherwise, the CAPWAP tunnel cannot be set up between the ACs.

Example

# Set the PSK used for encrypting sensitive information between ACs to huawei@123.

<HUAWEI> system-view
[HUAWEI] capwap inter-controller sensitive-info psk huawei@123
Warning: The ACs must have the same configuration. Otherwise, the link between them cannot be set up.
Warning: This operation may cause devices using CAPWAP connections to reset or go offline. Continue? [Y/N]:
