The VSP 7254XSQ has a PHYless design, which is typical for Data Center top of rack switches. The benefits of a PHYless design are lower power consumption and lower latency. However, due to the PHYless design, the following transceivers that require electronic dispersion compensation (EDC) for proper operation are not supported:
AA1403017-E6: 1-port 10GBASE-LRM SFP+
AA1403016-E6: 1-port 10GBase-ZR/ZW SFP+
The AA1403165 10GBASE-ZR CWDM DDI SFP+ transceiver can be substituted for AA1403016-E6 10GBASE-ZR/ZW SFP+
Software partitions the switch into two logical slots: Slot 1 and Slot 2.
Slot 1: 10 Gbps ports: 1 - 48
Slot 2: 40 Gbps ports: 1 - 6
Channelization is supported on the 40 Gbps QSFP+ ports.
MACsec support:
MACsec is only supported on the VSP 7254XTQ 10 Gbps ports.
MACsec is not supported on VSP 7254XSQ 10 Gbps ports
MACsec is not supported on VSP 7254XTQ and VSP 7254XSQ 40 Gbps ports whether channelization is enabled or not.
Port licensing support on the port licensed VSP 7254XSQ fiber switch:
24 ports (Slot 1, ports 25 to 48) out of the 48 1/10 GbE SFP/SFP+ ports require a Port License to be unlocked.
two ports (Slot 2, ports 5 and 6) out of the six 40 GbE QSFP+ ports require a Port License to be unlocked.
Port licensing support on the port licensed VSP 7254XTQ copper switch:
24 ports (Slot 1, ports 25 to 48) out of the 48 100 Mbps/1 GbE/10 GbE RJ-45 ports require a Port License to be unlocked.
two ports (Slot 2, ports 5 and 6) out of the six 40 GbE QSFP+ ports require a Port License to be unlocked.
1000BASE-T SFP (AA1419043-E6) will only operate at 1 Gbps speeds when used on a VSP 7254XSQ.
When you use 1 Gigabit Ethernet SFP transceivers on VSP 7254XSQ, the software disables auto-negotiation on the port:
If you use 1 Gbps fiber SFP transceivers, the remote end must also have auto-negotiation disabled.
If you use 1 Gbps copper SFP transceivers, the remote end must have auto-negotiation enabled. If not, the link will not be established.
When a port on VSP 7254XSQ is disabled or enabled, or a cable replaced, or the switch rebooted, the remote link can flap twice.
Enable auto-negotiation to ensure proper operation at 100 Mbps speeds on VSP 7254XTQ:
Link instability will be seen if both ends are set to 100 Mbps auto-negotiation disabled and you use a straight through cable.
If Link instability is seen when you use a cross-over cable, a port disable or enable can fix the issue.
