RSPAN
Remote Switch Port ANalyzer (RSPAN), also known as Remote Port Mirroring, enhances port
mirroring by enabling mirrored traffic to be sent to one or more switches or stacks on the
network using an intermediate VLAN for forwarding the mirrored traffic.

SPBM
Shortest Path Bridging MAC (SPBM) is a next generation virtualization technology that
revolutionizes the design, deployment and operations of Ethernet networks. SPBM enables
massive scalability while simultaneously reducing the complexity of the network.
Avaya networking products allow virtualization services at both layer 2 and layer 3, referred to
as L2VSN and L3VSN. The Avaya Ethernet Switch 4800 is capable of providing L2VSN support
connecting traditional Ethernet networks to an SPBM enabled network core, the ERS 4800
functions as a Backbone Edge Bridge. The 5.7 release introduces L2VSN capabilities to the
ERS 4800 product, whereas SPBM support is exclusive to the ERS 4800 and stacks of ERS
4800. The L3 (e.g. OSPF) features of the ERS 4800 cannot be supported simultaneously with
SPBM, they are mutually exclusive.
Avaya ERS 4800 Series supports the IEEE 802.1aq standard of SPBM, which allows for larger
Layer 2 topologies and permits faster convergence.
Note:
SPBM is not supported on the ERS 4500 series or hybrid stacks of ERS 4500 and ERS
4800.
