196 Configuring WSS System ParametersNN47250-102 (320666-G Version 02.01)d Select IP Services.e In the Task List panel, select NTP Server.2 Type the server address in the IP Address box.3 Click OK.4 Under NTP in the Content panel, select Enabled.5 To change the interval at which an NTP server is polled, specify its value in seconds (16 to 1024) in theUpdate Interval box. The default is 64 seconds.Configuring ARPThe Address Resolution Protocol (ARP) table maps IP addresses to MAC addresses. ARP is enabled by default on theWSS and cannot be disabled. An ARP entry is added to the table in one of the following ways:• Automatically by the WSS. The WSS adds a local entry for its own MAC address and adds dynamic entries foraddresses learned from traffic received by the WSS. When the WSS receives an IP packet, the WSS adds thepacket’s source MAC address and source IP address to the ARP table.• By the system administrator. Using WLAN Management Software, you can add permanent entries to the ARPtable. Permanent entries do not age out and remain in the table even after the WSS is rebooted.In addition to adding permanent ARP entries, you can set the amount of time unused dynamic entries remain in the tablebefore they are removed.1 In the Aging Time box, specify the amount of time a dynamic entry can remain unused before the entry isremoved from the ARP table.The value range for the aging timeout is 0 to 1,000,000 seconds. The default value is 1200 seconds. Todisable aging, specify 0 as the aging timeout.The local entry for the WSS, static entries, and permanent entries in the ARP table are not affected by theaging timeout.2 Access the Create ARP Entry wizard:a Select the Configuration tool bar option.b In the Organizer panel, click the plus sign next to the WSS.c Click the plus sign next to System.d Select IP Services.e In the Task List panel, select ARP Entry.3 In the MAC Address box, type the MAC address that the IP address is to be mapped to.4 In the IP Address box, type the IP address for the ARP entry.5 Click Finish.Viewing and Configuring VLANsA virtual LAN (VLAN) is a Layer 2 broadcast domain that can span multiple wired or wireless LAN segments. EachVLAN is a separate logical network, and, if you configure IP interfaces on the VLANs, WSS Software treats eachVLAN as a separate IP subnet.
