(Cisco Switch) Switchport mode trunk Switchport mode access Set port access Port access mode No experience with Cisco Switch 11.How would you proceed if the local R&D team requires more LAN ports, thereby affecting their work capacity? Short Term - Permit and assist RND to deploy any available adapters/switches to quickly expand their port count and not affect business continuity. Long Term - Coordinate with corporate IT to implement required equipment.
