IP Configuration
IPv4 Management and Interfaces
STEP 3
Cisco 500 Series Managed Switch Administration Guide
Enter one of the following fields for the Loopback Mask:
- Network Mask—Enter the mask of the IPv4 address of the loopback
interface.
- Prefix Length—Enter the prefix length of the IPv4 address of the
loopback interface.
• Administrative Default Gateway—Select User Defined and enter the
default gateway IP address, or select None to remove the selected default
gateway IP address from the interface.
• Operational Default Gateway—Displays the current default gateway
status.
If the device is not configured with a default gateway, it cannot
NOTE
communicate with other devices that are not in the same IP subnet.
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 device 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 device might receive a new IP address after
the renewal that requires setting the web-based 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 device is in Layer 3 system mode. This
mode enables configuring multiple IP addresses for device management, and
provides routing services.
The IP address can be configured on a port, a LAG, VLAN or loopback interface.
Operating in Layer 3 mode, the device routes traffic between the directly-
attached IP subnets configured on the device. The device 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.
