Brocade Communications Systems ICX 7250 series, Configuration Manual

Page: 81 / 483

Brocade devices support both classical IP network masks (Class A, B, and C subnet masks, and so on) and Classless Interdomain
Routing (CIDR) network prefix 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 prefix 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 significant bits (ones).
By default, the CLI displays network masks in classical IP address format (example: 255.255.255.0). You can change the display to
prefix format.
Assigning an IP address to a Brocade Layer 2 switch
To assign an IP address to a Brocade Layer 2 switch, enter a command such as the following at the global CONFIG level.
device(config)# ip address 10.45.6.110 255.255.255.0
Syntax: ip address ip-add rip-mask
or
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
Brocade FastIron 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
