Flooded Packets On All Vlans Are Received On A Server; The Server Is Configured As A Member Of Only A Subset Of Vlans. This Behavior Happens Because All Aggregator Ports Are, By Default, Members Of All (4094) Vlans; Steps To Take - Dell PowerEdge M IO Aggregator Command Reference Manual

Flooded packets on all VLANs are received on a server

Symptom: All packets flooded on all VLANs on an Aggregator are received on a server, even if the
server is configured as a member of only a subset of VLANs. This behavior happens because all
Aggregator 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 (
command).
FTOS#show interfaces switchport tengigabitethernet 0/1
Codes:
Name: TenGigabitEthernet 0/1

2. Assign the port to a specified group of VLANs (
status.
FTOS(conf)#interface tengigabitethernet 0/1
FTOS(conf-if-te-0/1)#vlan tagged 2-5,100,4010
