White Papers

To change to a different key on the interface, enable the new key while the old key is still enabled. Dell
EMC 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 EMC 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.
