TABLE 4 IP global parameters - Layer 2 switches (continued)
Parameter Description Default
addresses into the DHCP Discovery packets in a
round robin fashion.
DHCP Client-Based Auto-Conguration Allows the switch to obtain IP addresses from a
DHCP host automatically, for either a specied
(leased) or innite period of time.
Enabled
Interface IP parameters - Layer 2 switches
TABLE 5 Interface IP parameters - Layer 2 switches
Parameter Description Default
DHCP gateway stamp You can congure a list of DHCP stamp
addresses for a port. When the port receives a
DHCP/BootP Discovery packet from a client,
the port places the IP addresses in the gateway
list into the packet Gateway eld.
None congured
Conguring IP parameters - Layer 3 switches
The following sections describe how to
congure IP parameters. Some parameters can be congured globally while others can be
congured on individual interfaces. Some parameters can be congured globally and overridden for individual interfaces.
Conguring IP addresses
You can congure an IP address on the following types of Layer 3 switch interfaces:
• Ethernet port
• Virtual routing interface (also called a Virtual Ethernet or "VE")
• Loopback interface
• GRE tunnels
By default, you can congure up to 24 IP addresses on each interface.
You can increase this amount to up to 128 IP subnet addresses per port by increasing the size of the ip-subnet-port table.
Refer to the section "Displaying system parameter default values" in the FastIron Ethernet Switch Platform and Layer 2 Switching
Conguration Guide.
NOTE
Once you congure a virtual routing interface on a VLAN, you cannot congure Layer 3 interface parameters on individual
ports. Instead, you must congure the parameters on the virtual routing interface itself.
Brocade devices support both classical IP network masks (Class A, B, and C subnet masks, and so on) and Classless Interdomain
Routing (CIDR) network prex masks:
• To enter a classical network mask, enter the mask in IP address format. For example, enter "10.157.22.99 255.255.255.0" for
an IP address with a Class-C subnet mask.
• To enter a prex network mask, enter a forward slash ( / ) and the number of bits in the mask immediately after the IP address.
For example, enter "10.157.22.99/24" for an IP address that has a network mask with 24 signicant bits (ones).
