    Web-based management agent is discussed in the Manual. This manual provides a reference for all of the commands contained in the CLI for members of this series, including the DES-3028, DES-3028P, DES-3028G, DES-3052, and DES-3052P. Examples present in this manual may refer to any member of this series and may show different port counts, but are universal to this series of switches, unless otherwise stated.

    DES-3028 DES-3028P DES-3028G DES-3052 DES-3052P Layer 2 Fast Ethernet Switch CLI Reference Manual Appendix B ARP P ACKET ONTENT Address Resolution Protocol (ARP) is the standard method for finding a host's hardware address (MAC address) when only its IP address is known. This protocol is vulnerable so hackers can spoof the IP and MAC information in the ARP packets to attack a LAN (known as ARP spoofing).

  • Page 354 Configuration: The design of the Packet Content ACL on the DES-3028/28P/28G/52/52P series can inspect any specified content in the first 20 bytes of an ARP packet (up to 80 bytes in total at one time). It utilizes offsets to match individual fields in the Ethernet Frame. An offset contains 16 bytes and the switch supports 5 offsets with each offset being divided into a four 4-byte values in a HEX format.
