Configuring and managing IP interfaces
Many features, including the following, require an IP interface on the WSS:
• Management access through Telnet
• Access by WLAN Management Software
• Exchanging information and user data with other WSS switches in a Mobility Domain
IP interfaces are associated with VLANs. At least one VLAN on a WSS must have an IP interface to provide manage-
ment 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.
Adding an IP interface
You can add an IP interface to a VLAN by statically configuring an IP address or by enabling the Dynamic Host Config-
uration 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 WSS Software DHCP client enables a WSS 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 WSS 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 NRTL x.x.x, where x.x.x is the WSS Software version
The DHCP client is enabled by default on an unconfigured 2350 when the factory reset switch is pressed and held during
power on. The DHCP client is disabled by default on all other switch models, and is disabled on an 2350 if the switch is
already configured or the factory reset switch is not pressed and held during power on.
You can enable the DHCP client on one VLAN only.
WSS Software also has a configurable DHCP server. (See “DHCP server” (page 705).) You can configure a DHCP
client and DHCP server on the same VLAN, but only the client or the server can be enabled. The DHCP client and
DHCP server cannot both be enabled on the same VLAN at the same time.
