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 addresses to the VLAN.
To configure a VLAN with an IP interface, enter the following command in Configure
mode:
Create an IP interface for a VLAN.
Configure a secondary address to
an existing VLAN.
Specifying Ethernet Encapsulation Method
The IA supports two encapsulation types for IP. You can configure encapsulation type 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)
To configure IP encapsulation, enter one of the following commands in Configure mode:
Configure Ethernet II
encapsulation.
Configure 802.3
SNAP encapsulation.
Configuring Address Resolution Protocol (ARP)
The IA allows you to configure Address Resolution Protocol (ARP) table entries and
parameters. 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 a media or
MAC address is determined, the IP address/media address association is stored in an
ARP cache for rapid retrieval. Then the IP datagram is encapsulated in a link-layer frame
and sent over the network.
