IP interfaces

NOTE
This section describes IPv4 addresses. For information about IPv6 addresses, refer to the IPv6 addressing chapter.
Brocade Layer 3 switches and Layer 2 switches allow you to configure IP addresses. On Layer 3 switches, IP addresses are associated
with individual interfaces. On Layer 2 switches, a single IP address serves as the management access address for the entire device.
All Brocade Layer 3 switches and Layer 2 switches support configuration and display of IP addresses in classical subnet format (for
example, 192.168.1.1 255.255.255.0) and Classless Interdomain Routing (CIDR) format (for example, 192.168.1.1/24). You can use
either format when configuring IP address information. IP addresses are displayed in classical subnet format by default but you can
change the display format to CIDR.
Layer 3 switches
Brocade Layer 3 switches allow you to configure IP addresses on the following types of interfaces:
• Ethernet ports
• Virtual routing interfaces (used by VLANs to route among one another)
• Loopback interfaces
• GRE tunnels
Each IP address on a Layer 3 switch must be in a different subnet. You can have only one interface that is in a given subnet. For example,
you can configure IP addresses 192.168.1.1/24 and 192.168.2.1/24 on the same Layer 3 switch, but you cannot configure
192.168.1.1/24 and 192.168.1.2/24 on the same Layer 3 switch.
You can configure multiple IP addresses on the same interface.
The number of IP addresses you can configure on an individual interface depends on the Layer 3 switch model. To display the maximum
number of IP addresses and other system parameters you can configure on a Layer 3 switch, refer to "Displaying and modifying system
parameter default settings" section in the Brocade FastIron Platform and Layer 2 Switching Configuration Guide.
You can use any of the IP addresses you configure on the Layer 3 switch for Telnet, Web management, or SNMP access.
Layer 2 switches
You can configure an IP address on a Brocade Layer 2 switch for management access to the Layer 2 switch. An IP address is required
for Telnet access, Web management access, and SNMP access.
You also can specify the default gateway for forwarding traffic to other subnets.
