No, use frame when your talking about layer 2, packet when your talking about layer 3, and segment for layer 4. Datagram and protocol data unit (PDU) are general terms that can apply to any layer.
A switch forwards frames, while a router routes packets.

- icedchai 8y agoYou are technically correct. However, the term “Ethernet packet” is commonly used colloquially... it does not seem worth arguing about.
- packet_nerd 8y agoYeah, but the point is you wouldn't expect a competent network engineer to use the words "packet frames". And incompetence would seem to fit with the facts of the case, i.e. 911 was down for 2 days.
- icedchai 8y agoIt was probably down because the only person who knew how to use tcpdump (or equivalent) was on vacation. ;)
- EvanAnderson 8y agoI appreciate your insistence on speaking using precise terms. I'm sure I'm not the only one who gauges the knowledge-level and overall attention to detail of a speaker based on their use of precise, correct terminology. It's a useful handshaking technique I use for calibrating the technical content of my speech.
