ARP frame vs MAC frame

Threaded View
I am looking to see if anyone out there can give me some information on:
- what is ARP frame
- what is MAC frame
- or both are the same
when a node sends a packet (which packet, ARP, MAC , ?) to solicit a MAC
address, in other words while it's broadcasting.

thanks,
PS.

MAC (Media Access Control) is the address used by the low-level networking,
e.g. Ethernet or Arcnet handling. It points out a station in the local
network.

ARP is a protocol in the Internet Protocol (IP) stack for translation of IP
addresses (4 dotted bytes, e.g. 192.168.42.13) to the MAC addresses (e.g.
Ethernet 00:0d:20:52:68:34).

A MAC frame is, AFAIK, the IP packet sent on the link level with the MAC
headers and trailers.

An ARP frame is a link level frame carrying the ARP protocol data.

The MAC address is resolved by an ARP protocol query frame which is a
broadcast MAC frame. The addressed station sends back (non-broadcast) an ARP
response frame.

IMO the best thing is installing a packet sniffer and looking at some
packets. Of course, a good book helps ;-)

Absolutely!  Nothing better than seeing it in action - especially with a
decode.
