A traffic type for a service port. To distinguish specific service traffic flow type, the packet information from the user-side port is used, and this information is classfied to differnet cases that is represented by the value of variable zxAnSrvPortServiceMode. After distinguishing the service traffic flow type based on the packet information, a service port can be created, and additionally the packet can be modified if you want. For example: - translate user-vlan to new cvlan - add a svlan - modify the svlan when user-side packet is double tagged - translate the cos of svlan The following is the explanation of each value of variable zxAnSrvPortServiceMode. - untag(1) create a service port when user packet is untag. - untagAndEtype(2) create a service port when user packet is untag and has a specific Ethernet type. - cos(3) create a service port when user packet is priority tag. - tag(4) create a service port when user packet is single VLAN tag. - tls(5) create a service port for a TLS service. - tagAndEtype(6) create a service port when user packet is single VLAN tag and has a specific Ethernet type. - tagAndCos(7) create a service port when user packet is single VLAN tag and has a specific cos. - vlanRange(8) create a service port for a QinQ service. The user packet will add a svlan when the vlan tag is in the vlan range. - vlanRangeAndEtype(9) create a service port for a QinQ service. The user packet will add a svlan when the vlan tag is in the vlan range and has a specific ethernet type. - vlanRangeAndCos(10) create a service port for a QinQ service. The user packet will add a svlan when the vlan tag is in the vlan range and has a specific cos. - batchBindVlan(11) create a service port for a transparent service. - doubleVlan(12) create a service port when user packet is double VLAN tag. - doubleTlsVlan(13) create a service port for a double tag TLS service.
