Cisco C9200L-48P-4G User Manual

Connecting Devices to the Ethernet Ports
10/100/1000 Port Connections
The switch 10/100/1000 port configuration changes to operate at the speed of the attached device. If the
attached ports do not support autonegotiation, you can manually set the speed and duplex parameters.
Connecting devices that do not autonegotiate or that have the speed and duplex parameters manually set can
reduce performance or result in no linkage.
To maximize performance, choose one of these methods for configuring the Ethernet ports:
• Let the ports autonegotiate both speed and duplex.
• Set the interface speed and duplex parameters on both ends of the connection.
Auto-MDIX Connections
The autonegotiation and the auto-MDIX features are enabled by default on the switch.
With autonegotiation, the switch port configurations change to operate at the speed of the attached device. If
the attached device does not support autonegotiation, you can manually set the switch interface speed and
duplex parameters.
With auto-MDIX, the switch detects the required cable type for copper Ethernet connections and configures
the interface accordingly.
If auto-MDIX is disabled, use the guidelines in this table to select the correct cable.

100BASE-TX and 1000BASE-T traffic requires twisted four-pair, Category 5 or higher. 10BASE-T
traffic can use Category 3 cable or higher.
Auto-MDIX Connections
The autonegotiation and the auto-MDIX features are enabled by default on the switch.
With autonegotiation, the switch port configurations change to operate at the speed of the attached device. If
the attached device does not support autonegotiation, you can manually set the switch interface speed and
duplex parameters.
