Controller Based WLANs

Environment  : This article applies to all the controller models and OS versions.

At times when you try to configure VRRP authentication password, you may get an error like this:

(Aruba3400) #configure t
Enter Configuration commands, one per line. End with CNTL/Z
 
(Aruba3400) (config) #vrrp 10
(Aruba3400) (config-vrrp)#authentication aruba1234  //9 characters in the authentication string
                                         ^
% Invalid input detected at '^' marker.
 
(Aruba3400) (config-vrrp)#

The most likely reason for the error message would be the password string used is more than 8 characters. Aruba currently supports NOT more than 8 characters in the authentication password string.

Reduce the number of characters to 8 or less in the password string.
 
Once the characters are reduced to 8 or less, the configuration should take effect as shown below:
 
(Aruba3400) #configure terminal
Enter Configuration commands, one per line. End with CNTL/Z
 
(Aruba3400) (config) #vrrp 10
(Aruba3400) (config-vrrp)#authentication aruba123  //8 characters in the authentication string
(Aruba3400) (config-vrrp)#
 
Once done, you can proceed further with rest of the VRRP configuration.
