"switchport vlan mapping" - a must-know for a Cisco engineer?
I felt myself very ashamed yesterday: after almost a year of studying for the CCIE R&S exam, I couldn't create a working test VLAN to ping a directly connected switch!..[:$]
Here's the story (please excuse for a link to another site - I could copy-paste, but decided to be brief):
Could anyone please clarify why I wasn't able to use my test VLAN to ping the swtch on the other end of a direct link (that switch was a non-Cisco switch, but the same configuration worked well with a non-Cisco switch from another vendor).
Thanks in advance for you attention and help!
