set vlan dynamicegress
UsethiscommandtoadministrativelysetthedynamicegressstatusforoneormoreVLANs.
Syntax
set vlan dynamicegress vlan-list {enable | disable}
Parameters
Defaults
None.
Mode
Switchcommand,read‐write.
Usage
IfdynamicegressisenabledforaparticularVLAN,whenaportreceivesaframetaggedwiththat
VLAN’sID,theswitchwilladdthereceivingporttothatVLAN’segresslist.Dynamicegressis
disabledontheSecureStackC2bydefault.
Forexample,assumeyouhave20AppleTalkuserson
yournetworkwhoaremobileusers(thatis,
usedifferentportseveryday),butyouwanttokeeptheAppleTalktrafficisolatedinitsown
VLAN.YoucancreateanAppleTalkVLANwithaVLANIDof55withaclassificationrulethatall
AppleTalktrafficgetstaggedwithVLANID
55.Then,youenabledynamicegressforVLAN55.
Now,whenanAppleTalkuserplugsintoport
ge.3.5andsendsanAppleTalkpacket,theswitch
willtagthepackettoVLAN55andalsoaddport
ge.3.5toVLAN55’segresslist,whichallowsthe
AppleTalkusertoreceiveAppleTalktraffic.

Setting the Host VLAN
Purpose
ToconfigureahostVLANthatonlyselectdevicesareallowedtoaccess.Thissecuresthehostport
formanagement‐onlytasks.
vlan‐list SpecifiestheVLANsbyIDtoenableordisabledynamicegress.
enable|disable Enablesordisablesdynamicegress.
