Brocade FastIron Ethernet Switch Layer 3 Routing Configuration Guide - Manual (Page 36)

NOTE
Brocade Layer 2 switches also provide IP multicast forwarding, which is enabled by default. For
information about this feature, refer to chapter "IP Multicast Traffic Reduction" in the FastIron Ethernet
Switch IP Multicast Configuration Guide.
IP global parameters - Layer 2 switches
IP global parameters - Layer 2 switches TABLE 4
Parameter Description Default
IP address and
mask notation Format for displaying an IP address and its network mask
information. You can enable one of the following:
• Class-based format; example: 192.168.1.1 255.255.255.0
• Classless Interdomain Routing (CIDR) format; example:
192.168.1.1/24
Class-based
NOTE
Changing this
parameter affects the
display of IP addresses,
but you can enter
addresses in either
format regardless of the
display setting.
IP address A Layer 3 network interface address
NOTE
Layer 2 switches have a single IP address used for management
access to the entire device. Layer 3 switches have separate IP
addresses on individual interfaces.
None configured 5
Default gateway The IP address of a locally attached router (or a router attached to
the Layer 2 switch by bridges or other Layer 2 switches). The
Layer 2 switch and clients attached to it use the default gateway
to communicate with devices on other subnets. None configured
Address Resolution
Protocol (ARP) A standard IP mechanism that networking devices use to learn the
Media Access Control (MAC) address of another device on the
network. The Layer 2 switch sends the IP address of a device in
the ARP request and receives the device MAC address in an ARP
reply. Enabled
NOTE
You cannot disable
ARP.
ARP age The amount of time the device keeps a MAC address learned
through ARP in the device ARP cache. The device resets the
timer to zero each time the ARP entry is refreshed and removes
the entry if the timer reaches the ARP age. Ten minutes
NOTE
You cannot change the
ARP age on Layer 2
switches.
5 Some devices have a factory default, such as 10.157.22.154, used for troubleshooting during installation. For Layer 3 Switches, the
address is on port 1 (or 1/1).
