Excellent explanation of VLANs basics and VLAN trunking. This is very helpful. Great job, Wendell!

Cisco Live is a joy. "Summer camp for networking nerds" - the nickname - pretty much nails the vibe. New videos every Wednesday 9AM US Eastern time in June and July is the plan... I try to announce the lineup early each month: www.linkedin.com/posts/wendellodom_ciscolive-ciscochampion-activity-7205980839975813124-25Dj/ Those are the content videos... I don't pre-announce the review videos.

A very difficult topic made so easy here .Thanks . 1 question regarding native Vlan . When switch at the sending side sends a frame over a trunk a vlan header is added to the frame ,(this was the main difference between an access link & trunk link) .now wen at receiving side a switch receives a frame without the TAG how will it differentiate as it doesn’t rely on config for trunk link ,it sees the frame with tag and identifies .

Hi Sana, You're welcome! :-) If the receiving port is operating as a trunk (an important distinction), and the arriving frame does not have an 802.1Q tag/header, then it assumes the frame is in the native VLAN. More generally, when a receiving port is operating as a trunk, then it's obvious how it determines the VLAN to associate w/ incoming frames that arrive w/ 802.1Q tags. The case with no tag is when it relies on the port's native VLAN setting.

when setting up a port-channel as a trunk, do we have to setup the physical ports as trunk as well ?
@networkupskill
8 күн бұрын
Hi, Yep. Several settings must be consistent between the physical and portchannel, including trunking state (access or trunk) native VLAN if trunking, access VLAN if access, allowed VLAN list if trunking.

Is the "Flag" field in the dot1q encapsulation the "DEI" Field?. Also if SW1 and SW2 are connected via TRUNK - ACCESS instead of TRUNK - TRUNK? What happens then?
@networkupskill
3 ай бұрын
On flag and DEI, yes. Thanks, I hadn't noticed, since the discussion didn't mention it. Well, certainly you wouldn't want to have one switch trunk and the other operate as an access link. But the access switch will discard incoming frames that have 802.1Q headers. Those send by the trunking switch in the native VLAN won't have 802.1Q headers, so the switch operating as an access port will accept the frame and consider it to be in the same VLAN configured as the access VLAN. EG, if the trunk end had native VLAN 2, and the access end used access VLAN 2, then they could successfully communicate in VLAN 2. But if say the VLANs were 2 and 3 in that case, it would cause frames to hop to a new VLAN.

Hi Wendell - Just watching this video again - Just to confirm please that you wouldn't need a separate router if these switches can do L2 & L3? Thanks Stevo
@networkupskill

Yes indeed, Stevo - anything that'll perform routing meets the requirement. I like showing a separate router early in the learning path so it's more obvious that routing is required and to get folks thinking about what it's doing.

Yep! I'm working through the chapters in the CCNA Official Cert Guide, Volume 1, in order, to create a video on the first section from each chapter. The next two videos are from the two chapters on Spanning Tree. I'm also trying to release the videos on Wednesday mornings US Eastern time... so, Spanning Tree on June 19 and 26! Thanks for asking...
