If a dynamic IP address is retrieved from the DHCP server, select those of the
following fields that are enabled:
• Renew IP Address Now—The switch dynamic IP address can be renewed
any time after it is assigned by a DHCP server. Note that depending on your
DHCP server configuration, the switch might receive a new IP address after
the renewal that requires setting the web-based switch configuration utility
to the new IP address.
• Auto Configuration via DHCP—Displays status of Auto Configuration
feature. You can configure this from
DHCP Auto Configuration
Click Apply. The IPv4 interface settings are written to the Running Configuration
file.
Defining IPv4 Interface in Layer 3 System Mode
The IPv4 Interface page is used when the switch is in Layer 3 mode. This mode
enables configuring multiple IP addresses for switch management, and provides
routing services.
The IP address can be configured on a port, a LAG, or VLAN interface.
Operating in Layer 3 mode, the switch routes traffic between the directly-attached
IP subnets configured on the switch. The switch continues to bridge traffic
between devices in the same VLAN. Additional IPv4 routes for routing to non-
directly attached subnets can be configured in the IPv4 Static Routes page.
The switch software consumes one VLAN ID (VID) for every IP
NOTE
address configured on a port or LAG. The switch takes the first VID that is not
used starting from 4094.
To configure the IPv4 addresses:
Click IP Configuration > Management and IP Interface > IPv4 Interface. The
IPv4 Interface page opens.
For SG500X devices only, to enable IPv4 routing, check the Enable box. In Sx500
devices, when you change the system mode from Layer 2 to Layer 3 it
automatically enables IP routing.
This page displays the following fields in the IPv4 Interface Table:
• Interface—Interface for which the IP address is defined.
