VSP 4900 Series Operational Notes

VSP4900-24S fixed ports operate at 1 Gbps. If you connect a 10 Gbps DAC/SFP+ to a VSP4900-24S 1 Gbps fixed port, the system displays the following error message:

10Gb optical module inserted in 1Gb only port nn. Not supported.

Although the link successfully comes up, the operational speed shows as 10 Gbps instead of 1 Gbps. This scenario occurs when a 10 Gbps DAC/SFP+ is used to make any of the following connections from a VSP4900-24S 1 Gbps fixed port:

VIM5-2Y and VIM5-4Y Operational Notes

Note

Note

VIM5-2Y and VIM5-4Y are in end-of-sale status.

The IEEE 802.3by requirement for 25 G is that any transceiver or DAC 3 meters or longer, requires the use of forward error correction (FEC). Because the VIM5-2Y and VIM5-4Y do not support FEC, note the following considerations for proper operation with these VIMs:

You might experience CRC or link flap errors by using an unsupported 25 G transceiver.
