Configuring Ethernet Loopback Capability
By default, local aggregated Ethernet, Fast Ethernet, Tri-Rate Ethernet copper, Gigabit
Ethernet, and 10-Gigabit Ethernet interfaces connect to a remote system. To place
an interface in loopback mode, include the
NOTE: If you configure a local loopback on a 1-port 10-Gigabit IQ2 and IQ2-E PIC

hierarchy level, the transmit-path stops working, causing the remote end to detect
a link down.
To return to the default—that is, to disable loopback mode—delete the
