a. Establish communications with IBR via the serial interface ( See the section on communicating with
IBR via CLI).
b. Confirm that an Ethernet interface is enabled and connected to the network:
IBR101 # show interfaces
c. If the interface is connected, but not enabled, execute the following commands:
IBR101 (config) # interface gigabitethernet 2
where 2 is used as an example (could be 0, 1, or 2).
IBR101 (config-if-ge2) # no shutdown
IBR101 (config-if-ge2) # exit
IBR101 (config) # exit
IBR101 # show ip interfaces
The following is a sample output.
In the output above:
 up means the interface is enabled and connected;
 down means the interface is enabled, but not connected to another device; and
 disabled means the interface might not be connected.
d. If the Ethernet interface is connected and enabled, check that the default gateway is configured
and responds to pings.
e. Verify any VLAN settings on both IBR and the connecting device.
f. If an Ethernet link is unexpectedly down:
 Check the Ethernet cable with a suitable cable certifier (e.g., Fluke DTX 1800, or Byte
Brothers RWC 1000K).
 Check that speed and duplex settings on IBR match those on the switch port.
