---use of ethernet switch VLAN for LLT links
Cause
LLT links are setup using ethernet switch VLANs
---Each LLT link must be assigned to unique switch VLAN
---Need to confirm the VLAN configuration for each link
Solution
---Network admin changes VLAN ID for 2nd LLT link to be different that 1st LLT link.
