Port priority level	Normal
Port speed (on 10/100-Mbps Fast Ethernet)	auto (autonegotiate both speed and duplex)
Port duplex setting	•auto on 10/100-Mbps Fast Ethernet configured for auto port speed (to modify, set port speed manually) •half on 10-Mbps Ethernet, 100-Mbps Fast Ethernet, and 10/100-Mbps Fast Ethernet with speed configured manually •full on Gigabit Ethernet ports (cannot be modified)
VLAN	All ports are on VLAN 1
Flow control¹	•Fast Ethernet—Flow control set to off for receive (Rx) and on for transmit (Tx) •Gigabit Ethernet—Flow control set to off for receive (Rx) and desired for transmit (Tx)
