Usage
You can configure a maximum of six digest keys on an interface. Of the available
Information
six digest keys, the switches select the MD5 key that is common. The remaining
MD5 keys are unused.
To change to a different key on the interface, enable the new key while the old key
is still enabled. The system sends two packets: the first packet authenticated with
the old key and the second packet authenticated with the new key. This process
ensures that the neighbors learn the new key and communication is not disrupted
by keeping the old key enabled.
After the reply is received and the new key is authenticated, delete the old key. Dell
recommends keeping only one key per interface.
