Chapter 8: IP Routing Configuration Guide
Configuring IP Interfaces to Ports
You can configure an IP interface directly to a physical port. Each port can be assigned
multiple IP addresses representing multiple subnets connected to the physical port. For
example, to assign an IP interface ‘RED’ to physical port et.3.4, enter the following:
To configure a secondary address of 10.23.4.36 with a 24-bit netmask (255.255.255.0) on the
IP interface int4:
Configuring IP Interfaces for a VLAN
You can configure one IP interface per VLAN. Once an IP interface has been assigned to a
VLAN, you can add a secondary IP address to the VLAN. To create a VLAN called IP3,
add ports et.3.1 through et.3.4 to the VLAN, then create an IP interface on the VLAN:
To configure a secondary address of 10.23.4.36 with a 24-bit netmask (255.255.255.0) on the
IP interface int4:
Specifying Ethernet Encapsulation Method
The SmartSwitch Router supports two encapsulation types for IP. Use the interface create
ip
command to configure one of the following encapsulation types on a per-interface
basis:
• Ethernet II: The standard ARPA Ethernet Version 2.0 encapsulation, which uses a 16-
bit protocol type code (the default encapsulation method).
• 802.3 SNAP: SNAP IEEE 802.3 encapsulation, in which the type code becomes the
frame length for the IEEE 802.2 LLC encapsulation (destination and source Service
Access Points, and a control byte).
