20 CHAPTER 1: WX SWITCH OVERVIEW IP Services „ IP interfaces-You can configure an IP interface for each VLAN. „ IP ping and traceroute-You can test IP connectivity between the WX switch and other devices. „ Domain Name Service (DNS)-You can configure the switch to use DNS servers for name resolution. You also can configure a default domain name to append to hostnames. „ Network Time Protocol (NTP)-A WX switch can sets its time and date by polling an NTP server. „ System log-A WX generates log messages to log system events. The log messages are stored locally and also can be exported to syslog servers. „ Simple Network Management Protocol (SNMP)-A WX switch can be configured to generate SNMP traps for major system events. Authentication, Authorization, and Accounting „ 802.1X-A WX switch can authenticate users based on 802.1X protocols. Based on authentication, users are assigned VLAN membership, access control, and roaming boundaries. „ MAC authentication-If a device does not support 802.1X, you can configure authentication based on the source MAC address to assign VLAN membership, access control, and roaming boundaries. „ Guest authentication-Guests can be authenticated by a shared set of authorization attributes that assign VLAN membership, access control, and roaming boundaries. „ Local and remote authentication-You can authenticate users locally using information configured on the WX switch, or use a Remote Authentication Dial-In User Service (RADIUS) server. When you use a remote server, the WX switch can enhance performance by performing some of the AAA tasks locally or distributing the load across multiple servers. Roaming „ MAP access point roaming-You can configure the WX switch to allow users to roam from one MAP access point to another on the same WX switch. „ Mobility Domain™ roaming-You also can configure a group of WX switches to allow users to roam from one switch to another. Regardless of the wired subnet connections, each user maintains the same IP address and session across the network. „ Session management-You can display session information and statistics for users.

IP Services
IP interfaces—You can configure an IP interface for each VLAN.
IP ping and traceroute—You can test IP connectivity between the WX
switch and other devices.
Domain Name Service (DNS)—You can configure the switch to use
DNS servers for name resolution. You also can configure a default
domain name to append to hostnames.
Network Time Protocol (NTP)—A WX switch can sets its time and date
by polling an NTP server.
System log—A WX generates log messages to log system events. The log
messages are stored locally and also can be exported to syslog servers.
Simple Network Management Protocol (SNMP)—A WX switch can be
configured to generate SNMP traps for major system events.
Authentication,
Authorization, and
Accounting
802.1X—A WX switch can authenticate users based on 802.1X
protocols. Based on authentication, users are assigned VLAN
membership, access control, and roaming boundaries.
MAC authentication—If a device does not support 802.1X, you can
configure authentication based on the source MAC address to assign
VLAN membership, access control, and roaming boundaries.
Guest authentication—Guests can be authenticated by a shared set of
authorization attributes that assign VLAN membership, access control,
and roaming boundaries.
Local and remote authentication—You can authenticate users locally using
information configured on the WX switch, or use a Remote Authentication
Dial-In User Service (RADIUS) server. When you use a remote server, the WX
switch can enhance performance by performing some of the AAA tasks
locally or distributing the load across multiple servers.
Roaming
MAP access point roaming—You can configure the WX switch to
allow users to roam from one MAP access point to another on the
same WX switch.
Mobility Domain™ roaming—You also can configure a group of WX
switches to allow users to roam from one switch to another.
Regardless of the wired subnet connections, each user maintains the
same IP address and session across the network.
Session management—You can display session information and
statistics for users.
