The ethernet frame carries the IP (Internet Protocol) The Ethernet frame is made up of the following: 7 BYTE PREAMBLE 1 Byte "Start OF Frame" delimiter 6 byte destination address 6 byte source address 2 byte length or type 46 - 1500 bytes variable 802.2 or ethernet header and data 4 byte Frame Check sequence
Are standard access listS confIgured close to the source or destination address?
Standard access lists are placed close to the destination. Extended access list are placed close to the source. This is because extended ACL's look at the source and destination IP address, whereas standard ACL's look at the source IP address only.
