subnet, the output will be different.

For PICs that have a physical port, the LEDs indicate the status of the physical link. If the
LED is green, the physical link is up. If the LED is red or amber, the physical link is down.
Usually, when the LED is red, the receive port is not receiving a signal. If the LED is amber,
the receive port is getting a remote alarm from the device.
For PICs with no physical port, such as a tunnel or encryption PIC, the LED indicates the
status of the PIC.
The Tunnel PIC, which has no ports, has a single LED. Each LED has four different states,
described in Table 62 on page

For M7i and M10i routers, most PICs have an LED labeled
Some PICs have additional LEDs, often one per port. The meaning of the LED states
differs for various PICs. For more information, see the appropriate router PIC guide.
