show mac address table limitation?

Node Man

Hi Everyone,
Does a Show Mac Address Table command only show immediate MAC neighbors? What if there is a switch between the consoled switch and the target hosts?

Basically i want to know if i telnet into a switch, can i see the VOIP phones on the other side of an Adtran.

Example :

Switch - - - - - ADTRAN - - -- - - office full of voip phones.


Thanks!

Think of it this way. Where are MAC addresses passed? Do they cross layer three boundries? If so is your Adtran routing traffic or is it switching at L2?

Thanks so much Networker, your answers always coach me into learning more.

I just relized a huge missing piece of the puzzle: ADTRANS dont connect to VOIP phones, they are FXO/FXS !!!

Yeah that would cut the whole MAC thing out!
