Questions to Determine

• What VLANs are allowed on the trunk port connecting esxi-node-07 to sw-dist-02?
• Is VLAN 350 included in the allowed VLAN list on that trunk port?
• Does VLAN 350 exist in the switch's VLAN database?
• Is VLAN 350 active and not suspended or pruned by VTP/spanning-tree?
• Can you see tagged frames for VLAN 350 arriving at the switch port?
• What does the switch interface counters show -- are there any "unknown VLAN" drops?
• Is the VLAN trunking protocol (VTP) in a mode that would prune or not propagate VLAN 350 to sw-dist-02?
• Were VLANs 100 and 200 explicitly configured on the trunk while VLAN 350 was omitted?
