Context config>redundancy>multi-chassis>peer
Description This command configures the authentication key used between this node and the multi-chassis peer. 
The authentication key can be any combination of letters or numbers. 
Parameters authentication-key — Specifies the authentication key. Allowed values are any string up to 20 
characters long composed of printable, 7-bit ASCII characters. If the string contains special 
characters (#, $, spaces, etc.), the entire string must be enclosed within double quotes.
hash-key — The hash key. The key can be any combination of ASCII characters up to 33 (hash1-key) 
or 55 (hash2-key) characters in length (encrypted). If spaces are used in the string, enclose the 
entire string in quotation marks (“ ”). 
hash  — Specifies the key is entered in an encrypted form. If the hash or hash2 parameter is not used, 
the key is assumed to be in a non-encrypted, clear text form. For security, all keys are stored in 
encrypted form in the configuration file with the hash or hash2 parameter specified.
hash2  — Specifies the key is entered in a more complex encrypted form that involves more 
variables then the key value alone, this means that hash2 encrypted variable cannot be copied 
and pasted. If the hash or hash2 parameter is not used, the key is assumed to be in a non-
encrypted, clear text form. For security, all keys are stored in encrypted form in the configuration 
file with the hash or hash2 parameter specified.
