Syntax:

ip address

ip-addr

mask-bits

You also can enter the IP address and mask in CIDR format, as follows.

device(config)# ip address 10.45.6.1/24

To specify the Layer 2 switch default gateway, enter a command such as the following.

device(config)# ip default-gateway 10.45.6.1

Syntax:

ip default-gateway

ip-addr

NOTE

When configuring an IP address on a Layer 2 switch that has multiple VLANs, make sure the configuration includes a
designated management VLAN that identifies the VLAN to which the global IP address belongs. Refer to "Designated VLAN
for Telnet management sessions to a Layer 2 Switch" in the

FastIron Ethernet Switch Security Configuration Guide

Configuring Domain Name System resolver

The Domain Name System (DNS) resolver feature lets you use a host name to perform Telnet, ping, and traceroute commands. You can
also define a DNS domain on a Brocade Layer 2 switch or Layer 3 switch and thereby recognize all hosts within that domain. After you
define a domain name, the Brocade Layer 2 switch or Layer 3 switch automatically appends the appropriate domain to the host and
forwards it to the domain name server.

For example, if the domain "newyork.com" is defined on a Brocade Layer 2 switch or Layer 3 switch and you want to initiate a ping to
host "NYC01" on that domain, you need to reference only the host name in the command instead of the host name and its domain
name. For example, you could enter either of the following commands to initiate the ping.

device# ping nyc01

device# ping nyc01.newyork.com

Defining a DNS entry

You can define up to four DNS servers for each DNS entry. The first entry serves as the primary default address. If a query to the primary
address fails to be resolved after three attempts, the next gateway address is queried (also up to three times). This process continues for
each defined gateway address until the query is resolved. The order in which the default gateway addresses are polled is the same as the
order in which you enter them.

To define four possible default DNS gateway addresses, enter command such as the following:

device(config)# ip dns server-address 10.157.22.199 10.96.7.15 10.95.7.25 10.98.7.15

Syntax:

ip dns server-address

ip-addr

[

ip-addr

] [

ip-addr

] [

ip-addr

]

In this example, the first IP address in the

ip dns server-address

command becomes the primary gateway address and all others are

secondary addresses. Because IP address 10.98.7.15 is the last address listed, it is also the last address consulted to resolve a query.

Using a DNS name to initiate a trace route

Suppose you want to trace the route from a Brocade Layer 2 switch to a remote server identified as NYC02 on domain newyork.com.
Because the newyork.com domain is already defined on the Layer 2 switch, you need to enter only the host name, NYC02, as noted in
the following command.
