Configuring Interface Parameters
Assigning a port name
To modify Layer 2, Layer 3, or Layer 4 features on a port, refer to the appropriate section in this 
chapter or other chapters.  For example, to modify Spanning Tree Protocol (STP) parameters for a 
port, refer to “Changing STP port parameters” on page 330.
To configure trunk groups or dynamic link aggregation, refer to Chapter 8, “Link Aggregation”.
All device ports are pre-configured with default values that allow the device to be fully operational 
at initial startup without any additional configuration.  However, in some cases, changes to the port 
parameters may be necessary to adjust to attached devices or other network requirements. 
A port name can be assigned to help identify interfaces on the network.  You can assign a port 
name to physical ports, virtual routing interfaces, and loopback interfaces.
To assign a name to a port.
BigIron RX(config)# interface e 2/8
BigIron RX(config-if-e10000-2/8)# port-name Marsha Markey
Syntax: port-name <text>
The <text> parameter is an alphanumeric string.  The name can be up to 255 characters long on 
the device.  The name can contain blanks.  You do not need to use quotation marks around the 
string, even when it contains blanks.
Assigning an IP address to a port
To assign an IP address to an interface, enter the following commands.
BigIron RX(config)# interface e 1/8
BigIron RX(config)# ip address 192.45.6.110 255.255.255.0
Syntax: ip address <ip-addr> <ip-mask>
or
Syntax: ip address <ip-addr>/<mask-bits>
You also can enter the IP address and mask in CIDR format, as follows: 
BigIron RX(config)# ip address 192.45.6.1/24
