i n t e l l i g e n t w i r e l e s s p l a t f o r m Figure 2-18 Bridge Configuration Information 2.6.4 Configuring Spanning Tree Protocol (STP) STP is a Layer 2 link management protocol that provides path redundancy while preventing loops in the network. For a Layer 2 Ethernet network to function properly, only one active path can exist between any two redundant links. To create a fault-tolerant network, there needs to be a loop-free path between all nodes in the network.
i n t e l l i g e n t w i r e l e s s p l a t f o r m 2.6.5 STP Settings Configuration STP is disabled by default. The table below lists the default STP settings when the STP is enabled. Table 2-4 Default STP Values Setting Bridge priority Default Value 32768 Range 0-65535 Bridge max age 20 6-40 Bridge hello time 2 1-10 Bridge forward delay 15 4-30 Ethernet port (ETH A) path cost 100 0-65535 The cost of using the port to reach the root bridge.
i n t e l l i g e n t Range w i r e l e s s p l a t f o r m Setting Default Value Purpose spanning tree. A higher numerical value means a lower priority; thus, the highest priority is 8. Radio port (Radio A) path cost 100 0-65535 The cost of using the port to reach the root bridge. When selecting among multiple links to the root bridge, STP chooses the link with the lowest path cost and blocks the other paths. Each port type has its own default STP path cost.

i n t e l l i g e n t w i r e l e s s p l a t f o r m According to the IEEE 802.11 standard, Wired Equivalent Privacy (WEP) is intended to provide “confidentiality that is subjectively equivalent to the confidentiality of a wired local area network medium and that does not employ cryptographic techniques to enhance privacy.” WEP relies on a secret key that is shared between a mobile station and an access point. WEP uses the RC4 stream cipher invented by RSA Data Security.
i n t e l l i g e n t w i r e l e s s p l a t f o r m DHCP DHCP stands for ‘Dynamic Host Configuration Protocol’ and is a means for networked computers to get their TCP/IP networking settings from a central server. Importantly, DHCP assigns IP addresses and other TCP/IP configuration parameters automatically. SNMP Short for Simple Network Management Protocol, a set of protocols for managing complex networks. The first versions of SNMP were developed in the early 80s.

One airHaul unit is configured as ’Root Bridge’ device with one IP address assigned. A client PC (PC1) connected on the Ethernet interface of the Root Bridge device would need to be in the 192.168.1.x subnet (in this example the IP is 192.168.1.
i n t e l l i g e n t w i r e l e s s p l a t f o r m Appendix D – SNMP Trap The airHaul Nexus generates SNMP trap that can be forwarded to the SNMP Trap server. The SNMP Trap server IP address is set in section. The following table provides a list of SNMP traps generated. Trap IP address IP netmask Gateway SSID Radio Mode Message Object Identifier: 1.3.6.1.4.1.14882.2.1.1 Value: IP address> Object Identifier: 1.3.6.1.4.1.14882.2.1.2 Value: IP netmask> Object Identifier: 1.3.6.1.4.1.14882.2.1.
i n t e l l i g e n t w i r e l e s s p l a t f o r m Appendix E – SNMP MIB The airHaul device Mib can be downloaded at http://www.smartbridges.com/support/ah_nexus.asp . It contains all the MIB files used in the device. How to use the MIB files? ******************************************************************************* The user can use a MIB browser/compiler (available on the Internet) to convert the text file definitions to the proper OID form. This OID will be of form .1.3.1.6.1.4.1.14882.1.2.
