Hello,
Yes it works once You created VLANs and assigned an ID to it as described here
ID is the same as tag.
My point is that without creating VLANs and assigning IDs, just using 802.1Q values to specify allowed VLANs on EX interface is not supported.
ANyway, back to Your issue.
- Is this port STP-blocked by any chance?
- Is RSTP Edge enabled for this port?
- Is server using a multicast MAC perhaps? Then disable IGMP snooping for these VLANs
HTH
Thx
Alex
