Interfaces

Adding an IP

Interface

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.

Statically Configuring an IP Interface

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

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

Enabling the DHCP Client

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
