Create and assign VLANs to ports for logical segmentation of the network:
bash
Copy code
configure terminal

vlan <VLAN_ID>

name <VLAN_NAME>

exit

interface range gigabitEthernet 1/0/1 - 24

switchport mode access

switchport access vlan <VLAN_ID>

c. Setting Up QoS

Configure QoS policies to prioritize critical traffic:
bash
Copy code
policy-map QoS_POLICY

class <CLASS_NAME>

priority <BANDWIDTH>

exit

5. Management and Monitoring

a. Cisco DNA Center Integration
