Traffic provisioning
The following properties apply to a port in "network" port role:
• No VLAN tag/untag operation
• Provider Spanning Tree Protocol (provisionable, default is enabled)
• GVRP operation (provisionable, default is enabled)
The following properties apply to a port in "customer" port role:
• VLAN tag/untag operation
• No provider Spanning Tree Protocol
• No GVRP operation
Link Pass-through
The Fast Ethernet electrical interface and Gigabit Ethernet electrical and optical
interfaces on the X5IP option card support Link Pass-through modes.
The Ethernet port transmitter is shutdown in the upstream network due to the following
failures.
• loss of signal reported on a remote TransLAN Ethernet option card due to Ethernet
cable or fiber failure
• SDH/SONET network failure
• upstream equipment failure
Remote failures are reported in-band through the GFP-Client Signal Fail message. The
Link pass-through mode is only supported on ports that operate on a one-to-one
association with a WAN port using GFP encapsulation. Users can enable or disable the
Link pass-through mode per port.
LAN and WAN ports and VLAN
A VLAN can contain multiple LAN ports and multiple WAN ports.
Multiple LAN ports can be assigned to different VLANs, also mentioned as Virtual
LAN's. This keeps the traffic on each VLAN totally separate. VLAN groups are used
to connect LAN ports and WAN ports. The LAN ports are the physical 10BaseT or
100BaseT or gigabit Ethernet ports on the NE. All valid Ethernet packets are accepted
(both Ethernet 2 and IEEE 802.3). The WAN ports are the logical connection points to
the SDH channels. The LAN port is the interface between the customers Ethernet LAN
