What is Ethernet port flow control?
Ethernet flow control is a mechanism for temporarily stopping the transmission of data on Ethernet family computer networks. The goal of this mechanism is to avoid packet loss in the presence of network congestion. The first flow control mechanism, the pause frame, was defined by the IEEE 802.3x standard.
What is energy efficient Ethernet setting?
Energy-Efficient Ethernet (EEE) is a set of enhancements to the twisted-pair and backplane Ethernet family of computer networking standards that reduce power consumption during periods of low data activity.
How can I make my Ethernet power efficient?
Press in the IEEE 802.3az EEE ON/OFF button on the front panel to turn on the EEE feature. Disable it if you don’t want the network performance to be impacted due to the latency from the additional time required for the sleep and wake transition or if the remote side doesn’t support it.
Which is flow control mechanism does Ethernet use?
Ethernet flow control. Ethernet flow control is a mechanism for temporarily stopping the transmission of data on Ethernet family computer networks. The first flow control mechanism, the pause frame, was defined by the IEEE 802.3x standard.
How does priority flow control work in Ethernet?
Priority flow control. Ethernet flow control disturbs the Ethernet class of service (defined in IEEE 802.1p), as the data of all priorities are stopped to clear the existing buffers which might also consist of low priority data. As a remedy to this problem, Cisco Systems came up with its own priority flow control extension of the standard protocol.
How to configure flow control for a port?
Configure the flow control mode for the port. Return to privileged EXEC mode. Verify the interface flow control settings. (Optional) Save your entries in the configuration file.
What is the opcode for Cisco flow control?
As a remedy to this problem, Cisco Systems defined their own priority flow control extension to the standard protocol. This mechanism uses 14 bytes of the 42-byte padding in a regular pause frame. The MAC control opcode for a Priority pause frame is 0x0101.
