• Subnet Mask
This mask identifies the host address bits used for routing to specific subnets.
(Default: 255.255.255.0)
• Gateway IP address
IP address of the gateway router between this device and management stations
that exist on other network segments.
(Default: 0.0.0.0)
• MAC Address
The physical layer address for this Managed Switch.
• Restart DHCP
Requests a new IP address from the DHCP server.
If you lose your management connection, use a console connection and enter “show ip
interface” to determine the new switch address.
Manual Configuration
1. Click System, IP Configuration.
2. Select the VLAN through which the management station is attached, set the IP Address Mode to “Static,” enter the IP
address, subnet mask and gateway, then click Apply.
Using DHCP/BOOTP
If your network provides DHCP/BOOTP services, you can configure the Managed Switch to be dynamically configured by these
services.
1. Click System, IP Configuration.
2. Specify the VLAN to which the management station is attached, set the IP Address Mode to DHCP or BOOTP.
3. Click Apply to save your changes.
4. Then click Restart DHCP to immediately request a new address.
The Managed Switch will also broadcast a request for IP configuration settings on each
power reset.
Renewing DCHP
DHCP may lease addresses to clients indefinitely or for a specific period of time. If the address expires or the switch is moved to
another network segment, you will lose management access to the switch. In this case, you can reboot the switch or submit a
client request to restart DHCP service via the CLI.
1. If the address assigned by DHCP is no longer functioning, you will not be able to renew the IP settings via the web
interface.
2. You can only restart DHCP service via the Web interface if the current address is still available.
