System Configuration

• Subnet Mask: The mask that identifies the host address bits used for routing to 

specific subnets.

• Default Gateway: The default gateway is the IP address of the router for the access 

point, which is used if the requested destination address is not on the local subnet.
 If you have management stations, DNS, RADIUS, or other network servers 

located on another subnet, type the IP address of the default gateway router in the 
text field provided. Otherwise, leave the address as all zeros (0.0.0.0).

• Primary and Secondary DNS Address: The IP address of Domain Name Servers 

on the network. A DNS maps numerical IP addresses to domain names and can 
be used to identify network hosts by familiar names instead of the IP addresses. 
 If you have one or more DNS servers located on the local network, type the IP 

addresses in the text fields provided. Otherwise, leave the addresses as all zeros 
(0.0.0.0).

CLI Commands for TCP/IP Settings

 

– From the global configuration mode, enter the 

interface configuration mode with the 

interface ethernet

 command. Use the 

ip 

dhcp

 command to enable the DHCP client, or 

no ip dhcp

 to disable it. To manually 

configure an address, specify the new IP address, subnet mask, and default 
gateway using the 

ip address

 command. To specify DNS server addresses use the 

dns server

 command. Then use the 

show interface ethernet

 command from the 

Exec mode to display the current IP settings.

Enterprise AP(config)#interface ethernet
