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.
Configure IP addresses for accessing and managing the Switch from the ports belonging to the
pre-defined VLAN(s). See
Table 102 on page 252 for how many IP addresses you can
configure.
Level 7 Typically used for network control traffic such as router configuration messages.
Level 6 Typically used for voice traffic that is especially sensitive to jitter (jitter is the
variations in delay).
Level 5 Typically used for video that consumes high bandwidth and is sensitive to jitter.
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 Switch
loses these changes if it is turned off or loses power, so use the Save link on the top
navigation panel to save your changes to the non-volatile memory when you are
done configuring.
Cancel Click Cancel to begin configuring this screen afresh.
