    Hello, 

     

    I'm going to explain clearly :)

     

    I have 2 HP5700 in a stack routing several network. The network of production has a mask /24 and my customer wants to change it to /23.

     

    I want to know if i must shutdown the interface to change it OR not.

     

    I have several Bridge-Aggregation

     

    Here is the configuration.

     

    Thanks 

    Nicolas
