General

The General area displays the following fields:

Loopback—The following options are available:

Internal—No cable is needed to connect the input and output ports. The data is looped back within

the device itself. Applicable only for Gigabit and Fast Ethernet interfaces.

External—Input and output ports are physically connected by a cable to simulate a loopback. When

data i s tra nsm itted, it tr avels through t he ou tput port and en ters the d evice throug h t he input port .

Applic able o nly for Gi gabi t a nd Fast Ethe rnet in terfa ces.

Enabled—Packets are transmitted back to the source to test the interface functionality and ensure

that packets transmitted through the interface reach the destination. Applicable only for GRP

Ethernet interfaces.

Caution When the loopback for the Ethernet interface in the GRP is enabled, the Ethernet

communication link to the Cisco 12000 Series Router will be lost.

Disabled—Disabl es switches loopbac k off for GRP, Fa st and Gigab it Ethern et inter faces.

Keepalive Period—Displays set the keepalive period. The system sends packets after this interval to

know if the interface or the network is up for routin g packets. By default thi s interval is 10 seconds.
