6.5 IP Setup

Use t he I P Se t u p screen t o configure t he default gat eway device, t he default dom ain nam e server
and add I P dom ains.
6.5.1 IP Interfaces
The Swit ch needs an I P address for it t o be m anaged over t he net work. The fact ory default I P
address is 192.168.1.1. The subnet m ask specifies t he net work num ber port ion of an I P address.
The fact ory default subnet m ask is 255.255.255.0.
On t he Swit ch, an I P address is not bound t o any physical port s. Since each I P address on t he
Swit ch m ust be in a separat e subnet , t he configured I P address is also known as I P int erface ( or
rout ing dom ain) . I n addit ion, t his allows rout ing bet ween subnet s based on t he I P address wit hout
addit ional rout ers.
You can configure m ult iple rout ing dom ains on t he sam e VLAN as long as t he I P address ranges for
t he dom ains do not overlap. To change t he I P address of t he Swit ch in a rout ing dom ain, sim ply add
a new rout ing dom ain ent ry wit h a different I P address in t he sam e subnet .
