The following log information is displayed on Device A: 

<DeviceA>%Jul 12 08:29:17:786 2014 DeviceA IFNET/3/PHY_UPDOWN: Ten-

GigabitEthernet1/0/1 link status is DOWN. 

%Jul 12 08:29:17:787 2014 DeviceA IFNET/5/LINK_UPDOWN: Line protocol on the interface 

Ten-GigabitEthernet1/0/1 is DOWN.

%Jul 12 08:29:25:894 2014 DeviceA IFNET/5/LINK_UPDOWN: Line protocol on the interface 

Ten-GigabitEthernet1/0/2 is UP. 

The output shows that the physical status and link status of both Ten-GigabitEthernet 1/0/1 and 
Ten-GigabitEthernet 1/0/2 are down and then up.
