4 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. Table 14 outlines the interfaces to which you can assign IP 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. TABLE 14 Interface Assigning IP addresses Associated physical port Out of band or in band Management interface Ethernet 10/100/1000 port on active or redundant management module Any interface over which user packets Any interface module port are routed Any virtual interface over which user Any interface port packets are routed Loopback interface - Out of band In band In band In band This section describes the following: • BigIron RX Series support of sub-net masks • 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 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. • 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 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. 102 BigIron RX Installation Guide 53-1001811-01

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.
Table 14
outlines the interfaces to which you can assign IP
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.
This section describes the following:
BigIron RX Series support of sub-net masks
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
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.
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 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.
