Support of sub-net masks
The NetIron CES and NetIron CER 2000 Series devices support both classical IP network masks
(Class A, B, and C sub-net masks, and so on) and Classless Interdomain Routing (CIDR) network
prefix masks.
The following sub-net masks are supported by the NetIron CES and NetIron CER 2000 Series:
• To enter a classical network mask, enter the mask in IP address format. For example, enter
“209.157.22.99 255.255.255.0” for an IP address with a Class-C sub-net mask.
• To enter a prefix number for a network mask, enter a forward slash (/) and the number of bits
in the mask immediately after the IP address. For example, enter “209.157.22.99/24” for an
IP address that has a network mask with 24 significant (“mask”) bits.
Assigning an IP address to a management interface
Instead of assigning a global IP address to the NetIron CES and NetIron CER 2000 Series device for
system management purposes, you now assign an IP address to the management interface. The IP
address is assigned to the active management module port. If the active management module
becomes unavailable and the redundant module becomes the active module, the IP address is
assigned to the new active management module port.
For example, to assign the IP address 10.0.1.1 to the management interface, do the following.
1. At the opening CLI prompt, enter enable.
NetIron> enable
2. Enter the following command at the Privileged EXEC level prompt (for example, NetIron#), then
press Enter. This command erases the factory test configuration if still present.
NetIron# erase startup-config
CAUTION
Use the erase startup-config command only for new systems. If you enter this command on a
system you have already configured, the command erases the configuration. If you accidentally
erase the configuration on a configured system, enter the write memory command to save the
running configuration to the startup-config file.
3. Access the configuration level of the CLI by entering the following command.
NetIron# configure terminal Privileged EXEC Level
NetIron(config)# Global CONFIG Level
4. Configure the IP address and mask for the management interface by entering the following
commands.
NetIron(config)# interface management 1
NetIron(config-if-mgmt-1)# ip address 10.0.1.1 255.255.255.0
Syntax: enable [<password>]
Syntax: configure terminal
Syntax: interface management 1
Syntax: [no] ip address <ip-addr> <ip-mask>
