EtherChannel Disabled on all Ethernet ports
Jumbo frames Disabled on all Ethernet ports
1. On WS-X6502-10-Gigabit Ethernet ports, flow control on the receive side is always on and cannot be set to off. On
WS-X6704, WS-X6708-10-Gigabit Ethernet ports and Supervisor Engine 720-10 Gigabit Ethernet uplink ports flowcontrol
for both send and receive side can be set to off.
