Configuring LAN Interfaces

LAN Interface Configuration Examples

Cisco IOS Interface Configuration Guide

Ethernet Type Code Filtering Example

Using the same configuration as in the previous section, you could allow only the Macintosh traffic by

Ethernet type code with the following access list:

access-list 220 permit 0x809B 0x0000

interface lex 0

lex input-type-list 220

This access list permits only those messages whose protocol number matches the masked protocol

number in the first line. The implicit last entry in the list is a “deny everything” entry.
