Traffic provisioning
• No WAN port configurations are possible.
• When a virtual switch is switched from any of the other operational modes into
repeater mode, then all VLAN and QoS configuration information will be reset.
When the virtual switch is switched back again into the previous mode, then these
configuration settings will not become operational again but must be provisioned
again.
The Ethernet packets are carried across the SDH network in a channel. Each channel
comprises up to 63 VC12 or up to 2 VC3 concatenated. These VC12s and VC3s
behave in the same way as normal SDH VC12s from an E1 port or SDH VC3s from
an E3 port. There is some buffering in the NE, but it is still possible to lose packets
because the channel bandwidth can be less than the Ethernet traffic rate.
LAN-interconnect mode
The LAN-interconnect mode of operation offers dedicated WAN bandwidth to a single
end-user. Under the LAN-interconnect mode of operation, a Virtual Switch must only
contain LAN ports with the same CID (Customer ID) to ensure the entire WAN port
bandwidth allocated for the group is dedicated to a single end-user. Any combination
of LAN- and WAN-ports is allowed, but with a minimum of two ports to be
meaningful.
The following figure shows the network element configured in the LAN-interconnect
operation mode.
