Brocade FastIron Ethernet Switch Layer 3 Routing Configuration Guide - Manual (Page 24)

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 FastIron Ethernet Switch Platform and Layer 2 Switching Configuration Guide .
You can use any of the IP addresses you configure on the Layer 3 switch for Telnet or SNMP access.
Layer 2 switches
You can configure an IP address on a BrocadeLayer 2 switch for management access to the Layer 2
switch. An IP address is required for Telnet access and SNMP access.
You also can specify the default gateway for forwarding traffic to other subnets.
