Chapter 13: IPv4 and IPv6 Management Addresses
300
Overview
This chapter explains how to assign the switch an IP address. The switch
must have an IP address to perform the features in Table 27. It uses the
address as its source address when it communicates with other network
devices, such as TFTP servers, and Telnet management workstations.
To assign an IP address to the switch, you have to create an IPv4 routing
interface in one of its VLANs. You should assign the routing interface to
the VLAN from which the switch is to access the management devices.
The switch uses the IP address of the routing interface as its source
address.
Routing interfaces are also used to implement the IPv4 packet routing
feature, described in Chapter 104, “Internet Protocol Version 4 Packet
Routing” on page 1813. If you do not plan to use the packet routing
feature, create only one IPv4 routing interface on the switch. The switch
does not route packets if it has only one interface.
You may also assign the switch one IPv6 management address. However,
as the table indicates, the switch does not support all of the features when
assigned only an IPv6 address.
