Points to Note when using the WX1200 and
WX4400
Follow these best-practice recommendations during
configuration and implementation to avoid or solve
issues you might experience.
System Configuration Best Practices
3Com strongly recommends that you use 3Com Wire-
less Switch Manager (3WXM) for archiving and version
control of network-wide wireless LAN switch configura-
tions. 3Com also recommends that you archive the
CLI-based configuration files of individual WX switches
by copying the configurations to a server.
Client and AAA Best Practices
Follow these best-practice recommendations during
configuration and implementation to avoid or solve
issues you might experience.
Get Clients and AAA Working First
The greatest majority of installation issues are related to
clients and AAA server (authentication, authorization,
and accounting) operation. 3Com recommends first
establishing a baseline of proper operation with a sam-
pling of wireless clients and the AAA server you plan to

  • Page 4 ‡ Intel Centrino based chipsets might not associate with the SSID when power-save mode is enabled. Future drivers or laptop firmware might re- solve this issue, but until then 3Com recommends disabling power-save mode completely in the driver properties for the NIC.
  • Page 5 If you are not prepared to install Service Pack 2, 3Com strongly recommends that all wireless clients use Service Pack 1a with the following hotfixes installed: KB826942—This is the WPA Hotfix Rollup and is available through Microsoft Update KB834669—This corrects an 802.1x client issue...
  • Page 6 KB833865. If your network uses logon scripts, Active Directory group policies, or your users regularly share their laptops, 3Com recommends that you enable com- puter authentication to achieve full functionality over your wireless connection. Download current drivers for your NICs from the NIC vendor(s).
  • Page 7 Be sure to turn off Wireless Zero Config in Win- dows 2000 by disabling the service. If your wireless NIC’s driver includes the AEGIS pro- tocol manager for WPA support, 3Com recom- mends against installing it. Some drivers install this automatically if you run the setup.exe utility to install the driver.

This username is the same regardless of the configured protocol (PEAP-MS-CHAP-V2 or EAP-TLS). An appropriate userglob would be host/*.domain.com where domain.com is the Active Directory domain name.

Future versions of Steel Belted RADIUS and FreeRadius are planned to include standard definitions of the 3Com VSAs.
  • Page 11 The switch’s certificate can come from a certificate authority (CA) or it can be gener- ated and signed by the switch itself. 3Com recom- mends that you use certificates assigned by a CA. Certificates from a trusted CA are more secure than self-signed certificates.

You do not need to enable STP on the port that is directly connected to the MAP. If Spanning Tree Protocol (STP) is enabled on the port that is directly connected to a Distributed MAP, you might need to change the STP configuration on the port, to allow the MAP to boot.
  • Page 15 face on the WX switch or disable IGMP proxy reporting. To disable proxy reporting, use the com- mand set igmp proxy-report disable. Disabling proxy reporting can increase IGMP over- head traffic to the multicast router. Enable the IGMP querier only if needed. The IGMP pseudo-querier function is disabled by default.

  • Page 19 Autonegotiation with a 3Com switch that supports Smart Auto-Sensing may result in a 10Mbps link. (18325) If a WX1200 switch is attached to a 3Com switch that supports Smart Auto-Sensing, and autonegotiation is enabled at both ends of the link, the connection may be down-rated to a 10 MBPs full-duplex link on initial boot-up of the WX1200.
  • Page 20 Set the FDB timer (default 300 seconds) and the ARP timer (default 1200 seconds) to the same values on the WX switches. 3Com recommends using 300 sec- onds as the value for both timers. To set the FDB timer, use the set fdb agingtime command. To set the ARP timer, use the set arp agingtime command.
  • Page 21 time. This can occur if the DHCP server that responds to the DHCP request after the second reboot is not the same server that responded to the first request. This issue does not prevent the MAP from operating normally but can make managing the MAP more diffi- cult if the address the MAP receives the second time is not predictable.
  • Page 22 LAN S IRELESS WITCH AND ONTROLLER To restore the intended configuration, restart the switch. SSL connections to a WX switch from 3WXM or Web Manager can occasionally fail. (17772) If this issue occurs, MSS generates log messages such as the following: HTTPD Jan 12 00:58:16.807601 ERROR HTTPD: ssl accept error = SSL_ERROR_SYSCALL HTTPD Jan 12 00:58:16.828923 ERROR HTTPD: SSL...

(14833) If you type the clear usergroup or clear mac-user- group command to delete a user group or MAC user group, the display aaa command shows that the user group is gone.
  • Page 27 Web AAA client who fails authorization does not receive a failure message. (17901) If a user attempts to log in to the network on a Web AAA login page served by the WX switch, but fails authorization, the user does not receive a message indicating that they have been denied access.
