Access Port

When you configure switchport access vlan 20 on an interface:

  • This will make the interface become a layer 2 switchport or non-routeable port.
  • There is no 802.1q/ISL tagging involvement in this port as the traffic will be received and sent as untagged.
  • Because there is no tagging involved, the port has no clue what VLAN this frame should be. Therefore, any packets passing this port is assumed to belong to the VLAN assigned to this port. In this case vlan 20.
  • If you add the configuration with switchport mode access this will make the interface turned to nontrunking permanently and also negotiates or telling the other end of the link to be a nontrunk link. This interface will permanently become nontrunk interface regardless the other end is trunk or nontrunk link. With this in mind, if one port is configured with switchport mode access and other end port happens to be configured with switchport mode dynamic auto or switchport mode dynamic desirable

Gotta Set My Sail Again.

Few weeks ago, May 31, 2011, I sat my CCIE lab exam and failed. I knew I was going to fail but somewhere inside just want to keep trying and wanting to know how far I would get. This exam is not an impossible exam. Yes, it is hard, but not impossible to achieve. I’ve seen all of the technologies but I didn’t know it enough to pass.

Enough for the rant, I’m starting my INE WB from the beginning and it feels like things are keep unlocking itself and I have lots of Aha moments. I guess whatever I read before still inside, somewhere.

Previously I studied like a running train and tried to read as much as I could but not necessarily trying to understand it. That’s why I failed. I can be efficient to read more but it wasn’t effective enough to make me to understand it. This time is different, I have that eagerness to know more and don’t really care about the time, as long as I can learn 1-2 hours a day and make it count, it will be much better rather than learning until 2am in the morning but understand nothing.

Just before the exam, I was quite lucky to be able to attend Narbik’s 5-day Bootcamp, for those who wants to know what is it like in details, please visit this article. From my own point of view, this training has opened my eyes that CCIE is not for the faint-hearted, no shortcuts and you have to walk the process. I’m planning to join his 5-day bootcamp again in December 2011.

For all of those CCIE candidates out there, it’s hard but not impossible.
