Usage Information
You can congure 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 dierent key on the interface, enable the new key while the old key is still enabled. Dell Networking
OS sends two packets: the rst 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.
