IP Configuration

Overview

Cisco Small Business 200, 300 and 500 Series Managed Switch Administration Guide (Internal Version)
IP interface addresses can be configured manually by the user, or automatically
configured by a DHCP server. This section provides information for defining the
device IP addresses, either manually or by making the device a DHCP client.
This section covers the following topics:
• Overview
• IPv4 Management and Interfaces
• DHCP Server<300-500>
• IPv6 Management and Interfaces
• Domain Name
Some features are only available in Layer 2 or Layer 3 system mode, as described
below:
• In Layer 2 system mode, the device operates as a Layer 2 VLAN-aware
device, and has no routing capabilities.
• In Layer 3 system mode, the device has IP routing capabilities as well as
Layer 2 system mode capabilities. In this system mode, a Layer 3 port still
retains much of the Layer 2 functionality, such as Spanning Tree Protocol
and VLAN membership.
In Layer 3 system mode, the device does not support MAC-based VLAN,
Dynamic VLAN Assignment, VLAN Rate Limit, SYN Rate DoS Protection,
and Advanced QoS Policers.
Configuring the device to work in either mode is performed in the Administration >
System Settings page.
