Configuring IP addresses

Configuring IP addresses
The BigIron RX Series switches implement separate data and control planes. This architecture
affects how you assign IP addresses.
addresses.
In this table, "in band" refers to an interface over which user packets are routed, while "out of
band" refers to an interface over which control packets related to system management are
forwarded.

Support of sub-net masks

The BigIron RX Series switch supports both classical IP network masks (Class A, B, and C sub-net
masks, and so on) and Classless Interdomain Routing (CIDR) network prefix masks.

Assigning an IP address to a management interface

Instead of assigning a global IP address to the BigIron RX Series switch 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.

How to assign an IP address to a management interface
How to assign an IP address to an interface or virtual interface over which user packets are
routed
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.
