ZyXEL G-570S User’s Guide Appendix C Wir eless LANs 143 EAP Authentication EAP (Extensible Authentication Protocol) is an au thentication protocol that runs on top of the IEEE802.1x transport mech anism in order to support multiple types of user au thentication.
ZyXEL G-570S User’s Guide 144 Appendix C Wireless LANs However , MD5 authentication has some weakness es. Since the authenticat ion server needs to get the plaintext passwords, the passwords mu st be stored. Thus someone other than the authentication server may access the password file.

ZyXEL G-570S User’s Guide 152 Appendix D IP Subne tting Since the first octet of a class “A” IP address must contain a “0”, the first octet of a class “A” address can have a valu e of 0 to 127.
ZyXEL G-570S User’s Guide Appendix D IP Subnetting 153 Since the mask is always a continuous number of ones begin ning from the left, fo llowed by a continuous number of zeros for the remainder of the 32 bit mask, you can si mply specify the number of ones instead of writing the value of each octet.
ZyXEL G-570S User’s Guide 154 Appendix D IP Subne tting Note: In the following chart s, shaded/bolded last octet bit values indicate host ID bit s “borrowed” to form network ID bit s. The number of “borrowed” host ID bits determines the number of sub nets y ou can have.
