Fail-Safe/Local IP Address and Local Link Fail-Safe/Local IP - PowerPoint PPT Presentation

Fail-Safe/Local IP Address and Local Link � Fail-Safe/Local IP address - the IP address designed to be always reachable by the administrator with a direct Local Link connections Local Link Local Link 1 Mesh Manager Direct Wireless (802.11b/g) Connection to Station or Manager’s Default Setting 2.4GHz AP (Access Point) Mesh AP Working Mode: Manager Mesh Manager IP Address: 192.168.1.254 Fail-Safe/Local IP Address: 192.168.1.8 or Local Link 2 Direct Wire (Ethernet) Mesh Station Connection to Station or Manager’s Ethernet port Default Setting Mesh AP Working Mode: Station Fail-Safe/Local IP Address: 192.168.1.8

Accessing Mesh Manager and Station Access Mesh Manager Using two IP Addresses • Mesh Manager IP Address: 192.168.1.254 • Fail-Safe/Local IP Address: 192.168.1.8 Access Mesh Station • Fail-Safe/Local IP Address: 192.168.1.8 • Through Mesh Manager

Find Out Mesh Manager IP address Static setting or acquiring IP Address from DHCP Server Mesh Manager IP address could be assigned as static IP address or obtained from a DHCP server when “Mesh Manager IP Setting” is set to DHCP mode. Fail-Safe/Local IP address could be used to login to the Mesh Manager to observe what IP address is assigned by DHCP server. � Login Mesh Manager through Local Link and 192.168.1.8 � Review DHCP assigned IP address

Clear ARP Table on Laptop or PC for connecting to different MeshAPs with same (i.e.) Fail-Safe/Local IP address Situation : A number of MeshAPs are being accessed with a laptop or PC via Ethernet port to perform configuration. The Ethernet connection to the first device works fine, but connecting to subsequent MeshAPs with same IP address requires some technique to work correctly. Ethernet (Wire) Wireless Connection Ethernet cable Wireless connection move move 192.168.1.8 192.168.1.8 192.168.1.8 192.168.1.8 Station A Station B Station A Station B Explanation : The laptop or PC will record the MAC and IP address of the first MeshAP’s Ethernet port in its ARP (address resolution protocol) table. After the Ethernet connection is disconnected from the first MeshAP, its ARP table still retains the entry of IP to that MeshAP’s MAC address mapping of the first MeshAP. When the laptop or PC wants to connect to a different MeshAP but with the same IP address, the IP to MAC address mapping in ARP table will then be wrong and the connection will fail. Solution : Flush the ARP table of a Windows system by issuing “ arp –d ” command under “DOS Prompt” on laptop or PC .
