Viewing the Status of LFS-enabled Links

You can use the show interface command to view the status of LFS-enabled links.
Use one of the following commands to view the status of LFS-enabled links. Using these commands is optional and they can be entered in any order. For more information refer to the RUCKUS FastIron Command Reference.
  1. Enter the show interface command with the ethernet keyword, specifying an interface, to display general information about the status of LFS-enabled links. 
    device> show interface ethernet 1/1/10

10GigabitEthernet1/1/10 is down (remote fault), line protocol is down
  Hardware is 10GigabitEthernet, address is 0000.0027.79d8 (bia 0000.0027.79d8)
  Configured speed 10Gbit, actual unknown, configured duplex fdx, actual unknown
  Member of L2 VLAN ID 1, port is untagged, port state is BLOCKING
  BPDU guard is Disabled, ROOT protect is Disabled
  Link Fault Signaling is Enabled,  Link Error Dampening is Disabled
  STP configured to ON, priority is level0
  Flow Control is disabled
  mirror disabled, monitor disabled
<Truncated for brevity...>
    The above output shows that the LFS-enabled link (port 1/1/10) is down because of an error on the remote port.
  2. Enter the show span command with the brief keyword to display summarized information about the status of LFS-enabled links.
    device# show interfaces brief
Port  Link     State   Dupl  Speed Trunk Tag Pvid Pri MAC            Name
1/1/10  Err-LFS
  None    None  None  None  No  1    0   0000.0027.79d8
    The command output indicates that there is an error on the LFS-enabled link on port 1/1/10 and the link is down.
