Many features, including the following, require an IP interface on the WX 
switch:

„

Management access through Telnet

„

Access by 3Com Wireless Switch Manager

„

Exchanging information and user data with other WX switches in a 
Mobility Domain

IP interfaces are associated with VLANs. At least one VLAN on a WX switch 
must have an IP interface to provide management access. Optionally, the 
other VLANs configured on the switch also can each have an IP interface. 
Each IP interface must belong to a unique, nonoverlapping IP subnet.

You can add an IP interface to a VLAN by statically configuring an IP 
address or by enabling the Dynamic Host Configuration Protocol (DHCP) 
client on the VLAN.

To add an IP interface to a VLAN, use the following command:

set interface vlan-id ip {ip-addr mask | ip-addr/mask-length}

The MSS DHCP client enables a WX switch to obtain its IP configuration 
from a DHCP server. A switch can use the DHCP client to obtain the 
following configuration information:

„

IP address

„

Default router (gateway)

„

DNS domain name

„

DNS server IP address

The DHCP client is implemented according to “RFC 2131: Dynamic Host 
Configuration Protocol” and “RFC 2132: DHCP Options and BOOTP 
Vendor Extensions”. The client supports the following options:

„

(12) Host Name (the WX system name)

„

(55) Parameter request list, consisting of (1) Subnet Mask, (3) Router, 
(15) Domain Name, and (6) Domain Name Server

„

(60) Vendor Class Identifier, set to 3comx.x.x, where x.x.x is the MSS version
