md5: Specifies MD5 authentication.

cipher: Specifies a password in encrypted form.

plain: Specifies a password in plaintext form. For security purposes, the password specified in plaintext form will be stored in encrypted form.

string: Specifies the password. The plaintext password is a case-sensitive string of 1 to 16 characters. The encrypted password is a case-sensitive string of 33 to 53 characters.

Usage guidelines

ISIS-SPB adjacency authentication guarantees that SPBM nodes establish adjacencies only with trustworthy neighbors.

For correct authentication, make sure the authentication method and password are the same between SPBM neighbors. ISIS-SPB sends these authentication settings in hello packets. The recipients accept a hello packet only if the authentication settings in the packet match their local authentication settings.

Examples

# Set the adjacency authentication method to simple and the password to 123456 in plain text on HundredGigE 1/0/1.

<Sysname> system-view
[Sysname] interface hundredgige 1/0/1
[Sysname-HundredGigE1/0/1] spbm authentication-mode simple plain 123456
