1.2. Basic Configuration
Access Privileged EXEC Mode:
bash
Copy code
enable
Enter Global Configuration Mode:
bash
Copy code
configure terminal
Set the Hostname:
bash
Copy code
hostname YourSwitchName
Configure Management Interface:
bash
Copy code
interface vlan 1
ip address 192.168.1.1 255.255.255.0
no shutdown
exit
Set Default Gateway:
bash
Copy code
ip default-gateway 192.168.1.254
Table 1: Initial Setup Steps
| Task | Command |
| Access Privileged EXEC Mode | enable |
| Enter Global Configuration | configure terminal |
| Set Hostname | hostname YourSwitchName |
| Configure Management IP | interface vlan 1 then ip address 192.168.1.1 |
| Set Default Gateway | ip default-gateway 192.168.1.254 |
2. Implementing VLANs for Improved Traffic Management
2.1. Create VLANs
Define VLANs for Different Departments:
bash
Copy code
vlan 10
name Sales
exit
vlan 20
name Engineering
exit
2.2. Assign Ports to VLANs
Assign Ports to VLAN 10:
bash
Copy code
interface range ethernet 1/0/1-24
switchport mode access
switchport access vlan 10
exit
Assign Ports to VLAN 20:
bash
Copy code
interface range ethernet 1/0/25-48
switchport mode access
switchport access vlan 20
exit
Table 2: VLAN Configuration Steps
| Task | Command |
| Create VLAN 10 | vlan 10 then name Sales |
| Create VLAN 20 | vlan 20 then name Engineering |
| Assign Ports to VLAN 10 | interface range ethernet 1/0/1-24 then switchport access vlan 10 |
| Assign Ports to VLAN 20 | interface range ethernet 1/0/25-48 then switchport access vlan 20 |
3. Implementing Quality of Service (QoS)
3.1. Create Class Maps
Define Class Maps for Different Traffic Types:
bash
Copy code
class-map match-all VoIP
match ip dscp ef
exit
class-map match-all Video
match ip dscp af41
exit
3.2. Define Policy Maps
Create Policy Maps to Manage Bandwidth:
bash
Copy code
policy-map QoS_Policy
class VoIP
priority 1000
class Video
bandwidth 500
exit
3.3. Apply QoS Policies to Interfaces
Apply the QoS Policy:
bash
Copy code
interface range ethernet 1/0/1-48
service-policy input QoS_Policy
exit
Table 3: QoS Configuration Steps
| Task | Command |
| Create Class Maps | class-map match-all VoIP |
| Define Policy Maps | policy-map QoS_Policy |
| Apply Policy to Interfaces | interface range ethernet 1/0/1-48 then service-policy input QoS_Policy |
4. Enhancing Security
4.1. Enable Port Security
Configure Port Security:
bash
Copy code
interface range ethernet 1/0/1-48
switchport port-security
switchport port-security maximum 2
switchport port-security violation restrict
switchport port-security mac-address sticky
exit
4.2. Implement SSH for Secure Management
Enable SSH:
bash
Copy code
ip domain-name YourDomain.com
copyright key generate rsa
ip ssh version 2
username admin privilege 15 secret YourAdminPassword
Table 4: Security Configuration Steps
| Task | Command |
| Enable Port Security | switchport port-security |
| Set Maximum MAC Addresses | switchport port-security maximum 2 |
| Enable SSH | ip domain-name YourDomain.com |
5. Monitoring and Performance Management
5.1. Enable SNMP
Configure SNMP for Monitoring:
bash
Copy code
snmp-server community YourCommunityString ro
5.2. Use Cisco DNA Center for Insights
- Integrate with Cisco DNA Center for centralized management and insights into network performance.
5.3. Conduct Regular Backups
Backup Configuration:
bash
Copy code
copy running-config startup-config
Table 5: Monitoring Steps
| Task | Command |
| Enable SNMP | snmp-server community YourCommunityString ro |
| Conduct Regular Backups | copy running-config startup-config |
6. Utilizing Energy Efficiency Features
6.1. Implement Cisco EnergyWise
- Monitor and Manage Power Consumption: Utilize Cisco EnergyWise to track energy usage and identify opportunities to optimize power consumption.
6.2. Use Power over Ethernet (PoE)
- Connect Devices Efficiently: Leverage PoE capabilities to power devices such as IP phones and security cameras, reducing the need for additional power sources.
Table 6: Energy Efficiency Features
| Task | Description |
| Implement EnergyWise | Monitor and manage energy consumption |
| Utilize PoE | Power devices through network cables |
7. Final Checks and Documentation
7.1. Save Configuration
After completing all configurations, ensure they are saved:
bash
Copy code
write memory
7.2. Documentation
- Document Configuration Changes: Maintain accurate documentation of the switch configuration, including VLANs, QoS settings, and security policies.
Table 7: Final Steps
| Task | Command |
| Save Configuration | write memory |
| Document Configuration Changes | Keep a record of all configurations |
