slb group method <group_name> rc cookie_name [off-set] [rr|sr|lc] [threshold]
“cookie_name” - is required as is the “offset” value.
[off_set] - is the number of protected bytes in a backend server generated cookie. Users must allow at least four (4) bytes of free space within the server cookie value for the Array appliance to perform this task. The default value is zero (0).
[rr|sr|lc] - argument can be called the "first choice method". If a client request does not yet have an assigned real service, this method will be used to choose a real service for that client, based on the request properties appropriate to the group method. The [threshold] argument only applies if the "first choice method" is lc, and is the same as the group method lc threshold parameter.
