FIGURE 49 Transport service
The transport VFs that can extend outside of the VCS Fabric are numbered up through 4095, bound by
the 802.1Q interface. Because the extension port cannot support QinQ encapsulation, transport VFs
that have overlapping C-TAGs cannot be configured on the same port. In the initial release of this
feature, no Layer 2 or Layer 3 configuration is supported.
Transport VFs are created by configuring a transparent VLAN that is classified by a set of VLANs at a
trunk interface. The operational model is similar to the implementation of SVL (shared VLAN learning).
The forwarding behavior is that all service VFs in the transport VF instance are mapped to the
transparent LAN forwarding domain (individual VLAN isolation is not maintained), and all end stations
participating in the transport VF must have unique MAC addresses.
Transport VF classification rules
The following Transport Layer Security classification rules apply:
• Transport VFs can be configured only on a trunk port, by means of the transport-service tlsid
command in VLAN configuration mode.
• The maximum number of transport VFs that can be configured in this release is 1000.
• Both service and transport VFs can coexist on the same port. A C-TAG is assigned exclusively to a
service or transport VF.
• Multiple transport VFs can be configured on the same port.
• Control traffic is classified and handled as follows:
