QoS:TheseswitchesofferpowerfulQualityofService(QoS)functions.QoSsupportis
importantforreal‐timeapplicationsbasedoninformationtakenfromLayer2to
Layer4,suchasVoIP.
STP:Theseswitchesoffer802.1D‐STP,802.1w‐RSTPand802.1s‐MSTPspanningtree

VLAN:AllswitchmodelssupportPort‐basedVLANandIEEE802.1QTaggedVLAN,with
supportfor256activeVLANshavingVLANID’sfrom1to4094.TheVLANfeaturein
theswitchoffersthebenefitsofbothsecurityandperformance.VLANisusedto
isolatetrafficbetweendifferentusersandthusprovidesbettersecurity.Limiting
thebroadcasttraffictowithinthesameVLANbroadcastdomainalsoenhances
performance.
PortTrunking:AllowsoneormorelinkstobeaggregatedtogethertoformaLinkAggregation

PortMirroring:Portmirroringcopiestrafficfromaspecificporttoatargetport.Thismechanism
helpstracknetworkerrorsorabnormalpackettransmissionwithoutinterrupting

1.Verifythatthemini‐GBICmoduleiscompatiblewiththeSFPportontheswitch(forexample,
someswitchmanufacturersdesigntheirmini‐GBICmodulestobeoperableonlyintheirbranded
devices).
2.Verifythatthetypeofmini‐GBICyouhaveselectedforusewillbecompatiblewiththe
typeoffibreopticcablethatistobeused.
3.Verifythatthetypeofmini‐GBICyouhaveselectedforusewillbecompatiblewiththe
fibreoptictransceiverattheotherendofthelink(e.g.–compatiblewavelengthandstandard).
4.SlidethemodulealongtheslotandensurethatthemoduleisproperlyseatedagainsttheSFP
