EVC Definition
AnEVCisalogicalenti tythatprovidesameansforconnectingtwoendpointsintheTotal
Access5000andprovidesapathforEthernetframeswithaparticularVLANIDwithinthe
TotalAccess5000. TheEVCcross‐connectstwoormoreendpointsandprovidesthe
mechanismbywhichan
S‐tagpathiscreatedinthesystem.TheS‐tagcorrespondstothe
VLANID.
IntheTotalAccess5000,customertrafficswitchesthroughoutthesystemviaS‐tags
(outermostVLANtagonanEthernetpacket).Downstreamtrafficentersthesystemthrough
thenetworkportsontheGigESMand
isS‐tagswitchedtotheappropriateslot.TheGE8‐Port

NOTE
If the NetVanta 8044 management VLAN differs from the GigE SM
managementVLAN,createanEVCfortheGigESMtopasstheNetVanta

EVC Cross Connect Guidelines
Whencreatingacross‐connect,enforcethefollowingguidelines:
•AnEVCcannotbepartofanothercross‐connect
• EachEVCmusthaveauniqueS‐tag
