- 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.
