Troubles with vlan 1 between extreme and cisco

[popeye]

Hello everyone.
I on my Cisco Nexus 3064 and Extreme x650-24x configured 6 * 10G ports etherchannel. Then I built trunk on cisco and added tagged vlans on extreme. Everything is ok despite of vlan 1. I can't get traffic in vlan 1 although there are mac addresses in this vlan.
Who has any ideas?
Thank you.

On extreme all of the vlans is tagged.

On cisco at this trunk vlan 1 is native.

But, when I tried change the native vlan on cisco on this trunk my portchannel became down (all of the 6 10G ports)

afaik “switchport mode trunk” on cisco means ALL vlans tagged

If you add VLANs as tagged on a port at EXOS switches VLAN1 still is untagged.

You can set vlan 1 as native vlan on cisco side OR remove it on EXOS and add it as tagged again.

Hi popeye,

Usually the VLAN 1 should be untagged.

Is that the case on the EXOS?
