Usage
Information
You can configure a maximum of six digest keys on an interface. Of the available
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. Dell Networking OS 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.
NOTE: The MD5 secret is stored as plain text in the configuration file with
service password encryption. Write down or otherwise record the key. You
cannot learn the key once it is configured. Use caution when changing the
key.
