This behavior happens because allAggregator ports are, by default, members of all (4094) VLANs.Resolution: Configure a port that is connected to the server with restricted VLAN membership.Steps to Take:1. Display the current port mode for Aggregator L2 interfaces (show interfaces switchport interfacecommand).2. Assign the port to a specified group of VLANs (vlan tagged command) and re-display the port modestatus.FTOS#show interfaces switchport tengigabitethernet 0/1Codes: U - Untagged, T - Taggedx - Dot1x untagged, X - Dot1x taggedG - GVRP tagged, M - Trunk, H - VSN taggedi - Internal untagged, I - Internal tagged, v - VLT untagged, V - VLT taggedName: TenGigabitEthernet 0/1802.1QTagged: HybridSMUX port mode: Auto VLANs enabledVlan membership:Q VlansU 1T 2-4094Native VlanId: 1FTOS(conf)#interface tengigabitethernet 0/1FTOS(conf-if-te-0/1)#vlan tagged 2-5,100,4010FTOS(conf-if-te-0/1)#FTOS#show interfaces switchport tengigabitethernet 0/1Codes: U - Untagged, T - Taggedx - Dot1x untagged, X - Dot1x taggedG - GVRP tagged, M - Trunk, H - VSN taggedi - Internal untagged, I - Internal tagged, v - VLT untagged, V - VLT taggedName: TenGigabitEthernet 0/1802.1QTagged: HybridSMUX port mode: Admin VLANs enabledVlan membership:Q VlansU 1T 2-5,100,4010Native VlanId: 1
