Brocade Communications Systems ICX 7250 series, Руководство по настройке

Страница: 52 / 483

By default, you can configure up to 24 IP addresses on each interface.
You can increase this amount to up to 128 IP subnet addresses per port by increasing the size of the ip-subnet-port table.
Refer to the section "Displaying system parameter default values" in the Brocade FastIron Platform and Layer 2 Switching Configuration
Guide .
NOTE
Once you configure a virtual routing interface on a VLAN, you cannot configure Layer 3 interface parameters on individual
ports. Instead, you must configure the parameters on the virtual routing interface itself.
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 (for example, 255.255.255.0). You can change the display to
prefix format.
Assigning an IP address to an Ethernet port
To assign an IP address to port 1/1/1, enter the following commands.
device(config)# interface ethernet 1/1/1
device(config-if-1/1/1)# ip address 10.45.6.1 255.255.255.0
You also can enter the IP address and mask in CIDR format, as follows.
device(config-if-1/1/1)# ip address 10.45.6.1/24
Syntax: no ip address ip- addr ip-mask [ ospf-ignore | ospf-passive | secondary ]
or
Syntax: no ip address ip-addr/mask-bits [ ospf-ignore | ospf-passive | secondary ]
The ospf-ignore and ospf-passive parameters modify the Layer 3 switch defaults for adjacency formation and interface advertisement.
Use one of these parameters if you are configuring multiple IP subnet addresses on the interface but you want to prevent OSPF from
running on some of the subnets:
• ospf-passive - This option disables adjacency formation with OSPF neighbors. By default, when OSPF is enabled on an
interface, the software forms OSPF router adjacencies between each primary IP address on the interface and the OSPF
neighbor attached to the interface.
• ospf-ignore - This option disables OSPF adjacency formation and also disables advertisement of the interface into OSPF. The
subnet is completely ignored by OSPF.
NOTE
The ospf-passive option disables adjacency formation but does not disable advertisement of the interface into OSPF. To
disable advertisement in addition to disabling adjacency formation, you must use the ospf-ignore option.
Use the secondary parameter if you have already configured an IP address within the same subnet on the interface.
NOTE
When you configure more than one address in the same subnet, all but the first address are secondary addresses and do not
form OSPF adjacencies.
