Configuring IP parameters
NOTE
The device uses the lowest MAC address on the device (the MAC address of port 1 or 1/1) as the
MAC address for all ports within all virtual interfaces you configure on the device.
To add a virtual interface to a VLAN and configure an IP address on the interface, enter commands
such as the following.
BigIron RX(config)# vlan 2 name IP-Subnet_1.1.2.0/24
BigIron RX(config-vlan-2)# untag e1/1 to 1/4
BigIron RX(config-vlan-2)# router-interface ve1
BigIron RX(config-vlan-2)# interface ve1
BigIron RX(config-vif-1)# ip address 1.1.2.1/24
The first two commands create a Layer 3 protocol-based VLAN named "IP-Subnet_1.1.2.0/24" and
add a range of untagged ports to the VLAN. The router-interface command creates virtual interface
1 as the routing interface for the VLAN. The last two commands change to the interface
configuration level for the virtual interface and assign an IP address to the interface.
Syntax: router-interface ve <num>
Syntax: interface ve <num>
The <num> parameter specifies the virtual interface number. You can specify from 1 to the
maximum number of virtual interfaces supported on the device. To display the maximum number
of virtual interfaces supported on the device, enter the show default values command. The
maximum is listed in the System Parameters section, in the Current column of the virtual-interface
row.
For the syntax of the IP address, refer to "Assigning an IP address to an Ethernet port" on
page 154.
Deleting an IP address
To delete an IP address, enter a command such as the following.
BigIron RX(config-if-e1000-1/1)# no ip address 1.1.2.1
This command deletes IP address 1.1.2.1. You do not need to enter the subnet mask.
To delete all IP addresses from an interface, enter the following command.
BigIron RX(config-if-e1000-1/1)# no ip address *
Syntax: no ip address <ip-addr>

Changing the network mask display to prefix format

By default, the CLI displays network masks in classical IP address format (example:
255.255.255.0). If you enable the software to display IP subnet masks in CIDR format, the mask is
saved in the file in "/<mask-bits>" format. You can use the CIDR format to configure ACL entries
regardless of whether the software is configured to display the masks in CIDR format. To enable the
software to display the CIDR masks, enter the ip show-subnet-length command at the global
CONFIG level of the CLI. You can change the format to the CIDR prefix format (example: /18) by
entering the following CLI command.
BigIron RX(config)# ip show-subnet-length
Syntax: [no] ip show-subnet-length
