How can solved?

So now configure those 2 ports the following way:<BR /> - switch 1, port 1: vlan 71 untagged<BR /> - switch 2, port 1: vlan 171 untagged<BR /> <BR /> Notes:<BR /> - If you need to propagate more vlans, you can add them as tagged on the same ports<BR /> - This link should be the only one between your switches. Otherwise you'll have to deal with spanning tree / loop protection.<BR /> - Mid- and long-term you should definitely sort out your vlan design properly!<BR /> <BR /> carsten<BR /> Thu, 14 Sep 2017 10:41:00 GMT https://community.extremenetworks.com/t5/extremeswitching-exos-switch/propagate-vlan/m-p/17969#M681 cbuchenau 2017-09-14T10:41:00Z
