Note—If Auto-Negotiation is not enabled on a port, the EEE is disabled. The only exception is if the
link speed is 1GB, then EEE will still be enabled even though Auto-Negotiation is disabled.
Default Configuration
By default, 802.3 EEE is enabled globally and per port.
Interactions Between Features
802.3 EEE interactions with other features:
If auto-negotiation is not enabled on the port, the 802.3 EEE operational status is
•
disabled. The exception to this rule is that if the link speed is 1gigabit, EEE will still be
enabled even though Auto-Negotiation is disabled.
• If 802.3 EEE is enabled and the port is going up, it commences to work immediately in
accordance with the maximum wake time value of the port.
On the GUI, the EEE field for the port is not available when the Short Reach Mode option
•
on the port is checked.
• If the port speed on the GE port is changed to 10Mbit, 802.3 EEE is disabled. This is
supported in GE models only.
