Step 6. Create a VLAN, in case VLANs are used in the network.
Step 7. Create a VLAN interface (Should be configured when working with L3 only).
Step 8. Assign an IP address to the vlan interface.
Step 9. Allow ports that belong to LAG (port-channel 55) access VLAN 55.
Step 10. Set access ports VLAN ID to match the host VLAN ID. The default (native) VLAN ID that is
associated with access port is VLAN ID 1.
Step 11. Disable spanning tree algorithm.
NOTE: In order to avoid disabling redundant links among the switches, this step should be per-
formed in case there is more than one switch in the network
Step 12. Enable LACP.
NOTE: This step should be performed in case there is more than one switch in the network.
Step 13. Enable OSPF routing protocol (Should be configured when working with L3 only).
Step 14. Enable PFC on the switch.
Step 15. Enable PFC on the specific priority 3.
Step 16. Enable PFC on the port.
3.7.3.1.1 Using Global Pause Flow Control (GFC)
 Enable GFC on ports that are facing hosts (access ports).
