Networking OS Command Line Reference Guide.
Version Description
9.10(0.0) Introduced on the S3100 series.
Usage
Information
EEE is an IEEE 802.3 az standard that reduces power consumptions on Ethernet ports. When EEE is
enabled, transmission is stopped when there is no data to be transmitted and is resumed on arrival of new
packets. You can enable EEE only on on 1-Gigabit and 10-Gigabit native copper ports. On a TAA (Trade
Agreements Act) compliant system, EEE is enabled by default.
Example To enable EEE:
Dell(conf)# interface TenGigabitEthernet 0/0
Dell(conf-if-te-0/0)# eee
To disable EEE:
Dell(conf)# interface TenGigabitEthernet 0/0
Dell(conf-if-te-0/0)# no eee

Syntax
flowcontrol rx {off | on} tx {off | on} [negotiate | pause-threshold value
| resume-offset value]
To return to the default, use the no form of this command.
Parameters
rx on Enter the keywords rx on to process the received flow control frames on this
port.
rx off Enter the keywords rx off to ignore the received flow control frames on this
port.
tx on Enter the keywords tx on to send control frames from this port to the connected
