If you are adding more then one vlan to a port then it is considered a trunk port. Only one vlan can be added to a port as untagged. The equivalent configuration would be this:<BR /> <BR /> switchport trunk native vlan [MAN_vlan]<BR /> switchport trunk allowed vlan [list of the vlans whose traffics will be enabled on this port] \<BR /> <BR /> to:<BR /> <BR /> configure vlan MAN_vlan add port untagged<BR /> configure VLAN [list of the VLANs whose traffics will be enabled on this port] add port tagged<BR /> <BR /> Continue the second command until the port has been added into each VLAN individually. On some newer versions of EXOS you can put in a VLAN id list using the tag given to that VLAN<BR /> <BR /> Hope this helps!
