(SFP) transceivers.
SFP transceivers
This section describes how to select and install Small Form Factor Pluggable (SFP) transceivers.
Use an SFP transceiver for 1 Gigabit per second (Gbps) Ethernet connections.
The Avaya VSP 8200 supports SFP transceivers on ports 1/1-1/40 and 2/1-2/40.
The Avaya VSP 8400 ports can be used with SFP transceivers depending on the type of Ethernet
Switch Modules (ESM) installed. For information about ESM types for VSP 8400, see Installing the
Avaya Virtual Services Platform 8000 Series.
The Avaya VSP 7200 Series supports SFP transceivers on ports 1/1–1/48.
The Avaya VSP 4000 supports SFP transceivers on SFP ports 47 and 48, as well as on SFP+ ports
49 and 50. The VSP 4450GSX-PWR+ supports the SFP transceivers on SFP ports 13 to 48, as well
as on SFP+ ports 49 and 50.
Note:
When you use a 1 Gigabit SFP transceiver on a 10 Gigabit SFP+ port for the first time, it is
essential to enable auto-negotiate between two VOSS switches.
On the other hand, when using a 1 Gigabit SFP on a VSP 4000 switch that is connected to third
party switches at the remote end, auto-negotiate must be enabled at all times, irrespective of
whether the SFP is inserted in a 1 Gigabit SFP port or 10 Gigabit SFP+ port.
Important:
The VSP switches operate in forgiving mode for SFP transceivers, which means that the switch
will bring up the port operationally when using non-Avaya SFP transceivers. Avaya does not
provide support for operational issues related to these SFP transceivers, but they will operate
and the port link will come up. The switch logs the device as an unsupported or unknown
device.
Note:
Auto-negotiation is always disabled for 1 Gigabit Ethernet transceivers on VSP 7254XSQ, so for
proper operation with a 1000BASE-T SFP, the remote 1000BASE-T interface must have auto-
