Duplex mismatch occurs when two network devices connected to each other operate with different duplex settings, such as one device operating in full duplex mode while the other is operating in half duplex mode. This can result in performance issues, packet loss, and connectivity problems.
To avoid duplex mismatch errors between two switches, the following switchport configurations can be used:
A. Set both sides of the connection to auto-negotiate: Auto-negotiation is a process in which two devices exchange information about their capabilities to determine the best common settings for speed and duplex. This option allows both switches to determine the optimal settings and avoid any mismatch errors.
D. Set one of the connection to auto-negotiate and the other side to full duplex: This option allows the switch that is set to auto-negotiate to determine the optimal settings, while the other switch is manually set to full duplex, ensuring that the devices are operating at the same setting.
F. Set both sides of the connection to full duplex: This option manually sets both switches to full duplex, ensuring that there are no mismatch errors. However, this configuration may not work if one of the switches does not support full duplex.
The following switchport configurations can lead to duplex mismatch errors:
B. Set both sides of the connection to half duplex: This option manually sets both switches to half duplex, which can result in performance issues and packet loss.
C. Set one of the connection to auto-negotiate and the other side to half duplex: This option can lead to a duplex mismatch error, as the switch set to half duplex may not be able to handle the traffic from the switch set to auto-negotiate.
E. Set one of the connection to full duplex and the other side to half duplex: This option can lead to a duplex mismatch error, as the switch set to half duplex may not be able to handle the traffic from the switch set to full duplex.
In summary, to avoid duplex mismatch errors between two switches, it is recommended to either set both sides of the connection to auto-negotiate, set one side to auto-negotiate and the other side to full duplex, or manually set both switches to full duplex.
