i have no words enough to appreciatte what you do for the community, thanks a lot i had been looking for some labs and couldnt find anything

Hi there, I follow all the instruction and I get an error message while setting the EthChannel between the L3 switches. I get: Command rejected (Port-channel): Either port is L2 and port-channel is L3, or vice-versa. Do you know why?

[@JeremysITLab]

Make sure the 'no switchport' command is applied to all interfaces!

[@D15AV0W3D]

Also make sure you name the port group something different than the first port group you created on SW2

[@JonathanDaniels-du6uz]

yh happens to me as well

your videos are amazing and they helped me pass icnd1 a few months ago.you might of made a small mistake in the video. you had the ip address written as a /30 but when you configured it you made it a /24.

[@JeremysITLab]

Thanks, it seems I indeed made a mistake!

Hey Jeremy, Why is it that when you did the final configuration on SW4 that you did not do the encapsulation dot1q? can you explain why its done on the Cores and not on the switches? thank you.

Hi Jeremy I'm getting the following IP overlapping message when I try to add an IP address on "int range g0/1 - 2" on switch 3 when adding the ip address 23.0.0.2 255.255.255.0 to it. I get this message "% 23.0.0.0 overlaps with GigabitEthernet0/1". Not sure if one of the IP's are wrong. I'm not sure how to find a solution. If you can point out what I missed, I'd really appreciate it. Thanks Jeremy for all you do for us in the IT Networking community.

[@JeremysITLab]

Don't configure the IP address on the two physical interfaces (g0/1 - 2), configure it on the port-channel interface! You can't configure an IP address in the same subnet on different interfaces, so configuring the same IP address on two interfaces won't work.

Hi Jeremy! Are not the cables between the switches supposed to be crossover ones?

@JeremysITLab please review this lab because it's not clear... I followed the video and I had error.

[@stefanomaggiore15]

jeremy I had a problem command reject :The port is L2 and the channel-port is L3 or vice-versa I made a mistake because I didn't immediately put IP routing and no SW in the interface range and this error popped up but I solved it with the following configuration for layer 3 ether channel use this create logical channel interface Switch# configure terminal Switch(config)# interface port-channel 3 Switch(config-if)# no switchport Switch(config-if)# ip address 172.10.20.10 255.255.255.0 Switch(config-if)# end now for physical interface use: Switch# configure terminal Switch(config)# interface range gigabitethernet0/4 -5 Switch(config-if-range)# no ip address Switch(config-if-range)# channel-group 3 mode desirable Switch(config-if-range)# end Then in the other L3 switch following your configuration without forgetting IP routing and no SW everything is fine, I didn't understand how you didn't have this problem

[@MsVaradero1000]

same issue...
