Verifying LLDP
When ISLs are functioning correctly, the show lldp neighbors command reports on each neighbor
switch in the VCS Fabric cluster.
1. Enter the show lldp neighbors command to verify that LLDP reports on all of its neighbors.
switch1# show lldp neighbors

2. If neighbors are missing, you will need to perform further debugging or contact your switch support
provider.
Checking for CPU overload
An abnormally high CPU load can cause an ISL to malfunction. Use the show process cpu command
as described in
CPU use is unexpectedly high on page 682 to troubleshoot an overloaded CPU.
License is not properly installed
If a licensed feature is not functioning, a probable reason is that the license for that feature has not
been installed correctly. Either the license was not installed, or it was installed and a required system
reboot was not performed.
If on a Brocade VDX 6720-24 or VDX 6730-32 switch only eight Ethernet ports are working, it is
probable that no Dynamic Ports on Demand (DPOD) license is installed. Similarly, if on a Brocade
VDX 6720-60 or Brocade VDX 6730-76, only 40 Ethernet ports are working, it is probable that no
DPOD license is installed.
If on a Brocade VDX 6720-60 or Brocade VDX 6730-76 50 Ethernet ports are working but the
remaining 10 are not, it is likely that you have the DPOD1 license installed, but not the DPOD2
license.
If you are unable to add a third switch to a VCS Fabric cluster, it is likely that the VCS Fabric license is
not installed.
If you are unable to connect an FCoE device or unable to use Fibre Channel ports on a Brocade VDX
6730 switch, it is likely that the FCoE license is not installed.
If you suspect a license is not properly installed, complete the following steps.
1. In privileged EXEC mode, enter the show license command to display the currently installed
licenses.
switch# show license
