Chapter 7: SFP+
This chapter provides installation procedures and specifications for Small Form Factor Pluggable
plus (SFP+) transceivers.
SFP+ transceivers
This section describes how to select and install Small Form Factor Pluggable plus (SFP+)
transceivers.
Use an SFP+ transceiver or direct attach cable for 10 Gigabit per second (Gbps) Ethernet
connections. SFP+ transceivers are similar to SFP transceivers in physical appearance but SFP+
transceivers support 10 Gbps connections. SFP+ modules do not interoperate with SFP modules.
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 on ESM types for VSP 8400, see Installing the
Avaya Virtual Services Platform 8000 Series, NN47227-300.
The Avaya VSP 7200 Series supports SFP+ transceivers on ports 1/1–1/48.
The Avaya VSP 4000 supports SFP+ transceivers on fiber ports 49 and 50.
Important:
• The VSP switches operate in forgiving mode for coarse wave division multiplexing
(CWDM) and dense wave division multiplexing (DWDM) SFP+ transceivers, which means
that the switch will bring the port up operationally when using non-Avaya SFP+
transceivers. For all other SFP+ transceivers, the VSP switches operate in strict mode,
which means that the switch will not bring the port up operationally when using non-Avaya
SFP+ transceivers.
• The VSP switches operate in forgiving mode for SFP+ direct attach cables (DAC) when
using non-Avaya direct attach cables. Avaya does not provide support for operational
issues related to these DACs, but they will operate and the port link will come up.
Note:
Although VSP 8000 and VSP 7200 Series support 10G and 40G DAC cables in
forgiving mode, the output to the command show pluggable-optical-modules
