Chapter 3: IP Routing Configuration GuideSSR User Reference Manual3 - 3Configure IP Interfaces for a VLANYou can configure one IP interface per VLAN. Once an IP interface has been assignedto a VLAN, you can add a secondary IP addresses to the VLAN.To configure a VLAN with an IP interface, enter the following command in Configuremode:Specify Ethernet Encapsulation MethodThe SmartSwitch Router supports two encapsulation types for IP. You can configureencapsulation type on a per interface basis.• Ethernet II: The standard ARPA Ethernet Version 2.0 encapsulation, which uses a16-bit protocol type code (the default encapsulation method)• 802.3 SNAP: SNAP IEEE 802.3 encapsulation, in which the type code becomes theframe length for the IEEE 802.2 LLC encapsulation (destination and source ServiceAccess Points, and a control byte)To configure IP encapsulation, enter one of the following commands in Configuremode.Configure Address Resolution ProtocolThe SSR allows you to configure Address Resolution Protocol (ARP) table entries andparameters. ARP is used to associate IP addresses with media or MAC addresses.Taking an IP address as input, ARP determines the associated MAC address. Once amedia or MAC address is determined, the IP address/media address association isConfigure a secondary address to anexisting IP interface.interface add ipaddress-netmask[broadcast padd r>]Create an IP interface for a VLAN. interface create ipaddress-mask vlanConfigure a secondary address to anexisting VLAN.interface add ipaddress-netmaskvlanConfigure Ethernet II encapsulation. interface create ipoutput-mac-encapsulation ethernet_IIConfigure 802.3 SNAP encapsulation. interface create ip out-put-mac-encapsulation ethernet_snap
