Basic IP configuration
NOTE
The terms Layer 3 Switch and router are used interchangeably in this chapter and mean the same.
Basic IP configuration
IP is enabled by default. Basic configuration consists of adding IP addresses for Layer 3 Switches,
enabling a route exchange protocol, such as the Routing Information Protocol (RIP).
If you are configuring a Layer 3 Switch, refer to “Configuring IP addresses” on page19 to add IP
addresses, then enable and configure the route exchange protocols, as described in other chapters
of this guide.
If you are configuring a Layer 2 Switch, refer to “Configuring the management IP address and
specifying the default gateway” on page88 to add an IP address for management access through
the network and to specify the default gateway.
The rest of this chapter describes IP and how to configure it in more detail. Use the information in
this chapter if you need to chan ge some of the IP parameters from their default values or you want
to view configuration information or statistics.
IP configuration overview
Brocade Layer 2 Switches and Layer 3 Switches support Internet Protocol version 4 (IPv4) and IPv6.
IP support on Brocade Layer 2 Switches consists of basic services to support management access
and access to a default gateway.
