Configuration 802.11 Configuration4-194.5.4 MAC AddressA MAC address is a unique identifier that distinguishes different devices on the 802.11network. It is the same as the unit’s hardware address.For networking purposes, the MSS can be configured to use either the PC card’s MACaddress or its own internal MAC address (the default) with the Change 80211MACADDRESS command. Using the MSS MAC address allows for more seamlessoperation when switching between wired and wireless networking.Figure 4-37: Configuring the MAC Address4.5.5 Extended Service Set ID (ESSID)Whenever there is more than one ESS in a wireless LAN architecture, devices need to betold which ESS they belong to. The ESSID ensures that devices communicate with the rightAP.To tell the MSS which ESS it belongs to, enter the Change 80211 ESSID command. Theexact string you enter will be determined by the settings of the AP with which you want theMSS to communicate.Figure 4-38: Configuring the ESS IDSetting the ESSID to none (Change 80211 ESSID None) allows the MSS to associate withany AP within range.Local>> CHANGE 80211 MACADDRESS CARDLocal>> CHANGE 80211 RESETorLocal>> CHANGE 80211 MACADDRESS MSSLocal>> CHANGE 80211 RESETLocal>> CHANGE 80211 ESSID “floor3”Local>> CHANGE 80211 RESET
