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 conguring an IP address on a Layer 2 switch that has multiple VLANs, make sure the conguration includes a
designated management VLAN that identies 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 Conguration Guide.
Conguring 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 dene a DNS domain on a Brocade Layer 2 switch or Layer 3 switch and thereby recognize all hosts within that domain. After you
dene 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 dened 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
Dening a DNS entry
You can dene up to four DNS servers for each DNS entry. The rst 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 dened 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 dene 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 rst 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
identied as NYC02 on domain newyork.com.
Because the newyork.com domain is already dened on the Layer 2 switch, you need to enter only the host name, NYC02, as noted in
the following command.
device# traceroute nyc02
Syntax: traceroute host-ip-addr [ maxttl value ] [ minttl value ] [ numeric ] [ timeout value ] [ source-ip ip-addr ]
