8.6 IP Setup
Use the IP Setup screen to configure the default gateway device, the default
domain name server and add IP domains.
8.6.1 IP Interfaces
The Switch needs an IP address for it to be managed over the network. The
factory default IP address is 192.168.1.1. The subnet mask specifies the network
number portion of an IP address. The factory default subnet mask is
255.255.255.0.
On the Switch, as a layer-3 device, an IP address is not bound to any physical
ports. Since each IP address on the Switch must be in a separate subnet, the
configured IP address is also known as IP interface (or routing domain). In
addition, this allows routing between subnets based on the IP address without
additional routers.
You can configure multiple routing domains on the same VLAN as long as the IP
address ranges for the domains do not overlap. To change the IP address of the
Level 4 Typically used for controlled load, latency-sensitive traffic such as SNA
(Systems Network Architecture) transactions.
Level 3 Typically used for “excellent effort” or better than best effort and would
include important business traffic that can tolerate some delay.
Level 2 This is for “spare bandwidth”.
Level 1 This is typically used for non-critical “background” traffic such as bulk
transfers that are allowed but that should not affect other applications
and users.
Level 0 Typically used for best-effort traffic.
Apply Click Apply to save your changes to the Switch’s run-time memory. The

Save link on the top navigation panel to save your changes to the non-
volatile memory when you are done configuring.
