In fairness to the original poster, different manufacturers, and even within Cisco, different product lines, have different ways of entering/configuring MAC's.
True, a MAC is 48 bits, and true, there are different ways of representing them. Most books I have read use the xxxx.xxxx.xxxx format. some sources might use colons instead of periods. But in terms of configuration, on a Cisco router the configuration format is 1224.5678.abcd while on a catalyst 5000 switch the format is 12-34-56-78-ab-cd The guy who posted the original question noted that on 3com garbage equipment the format is 12:23:56:78:ab:cd Chuck ""Logan, Harold"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Those are both valid MAC formats.
