🎯 Project Objective

• Configure Syslog on routers and switches to send logs to the Syslog server.
• Enable SNMP v2c for basic monitoring.
• Verify network connectivity between all devices.
• Document configurations, steps, and verification process.

---

🌐 Network Topology

• 2 Routers
• 2 Switches
• 4 PCs
• 1 Server (SyslogSV)

🔧 Lab Steps

1. Assign IP addresses to routers, switches, PCs, and server.
2. Configure routing between R1 and R2.
3. Configure switch VLAN interfaces for management.
4. Test basic connectivity using ping.
5. Configure Syslog on all devices:

   logging 10.0.20.10
   logging trap informational
   

6. Configure SNMP v2c on all devices:

   snmp-server community public RO
   

7. Verify Syslog logs appear on server.
8. Verify SNMP configuration using show running-config | include snmp.

🌐 Verify Syslog Configuration

** Verify Logs on Syslog Server **

🗺️ Verify SNMP Configuration

** Commands on All Devices **

R1#show running-config | include snmp snmp-server community public RO

R2#show running-config | include snmp snmp-server community public RO

SW1#show running-config | include snmp snmp-server community public RO

SW2#show running-config | include snmp snmp-server community public RO

Verification Notes:

• Packet Tracer MIB Browser may not successfully poll SNMP, due to PT limitations.

• Configuration exists on all devices, meeting lab objectives.

---

⚡ How to Run Lab

1. Open Packet Tracer and load lab file/a.pkt.
2. Ensure all devices are powered on.
3. Verify that IP addressing matches the IP Addressing Table.
4. Test connectivity:
   • Ping between PCs in the same LAN.
   • Ping between PCs across different LANs.
5. Verify Syslog logs appear on the Syslog server (Server → Services → Syslog).
6. Verify SNMP configuration using: show running-config | include snmp
7. Check screenshots folder for reference outputs.

🧱 Lab Limitations

• Packet Tracer Limitation: Syslog server is available only under Services → Syslog. There is no Syslog option in the Desktop tab.

• SNMP Limitation: Packet Tracer does not fully support SNMP polling with the MIB Browser. The SNMP configuration (snmp-server community public RO) is visible in the running config but cannot be fully verified through SNMP queries.

• Real-World Note: In a real lab, FreeSyslog or other tools would be used for Syslog collection, and SNMP would be verified with an SNMP manager tool like snmpwalk or SolarWinds.

---

🎓 Learning Outcomes

After completing this lab, learners will be able to:

• Configure Syslog on Cisco routers and switches for centralized logging.
• Configure SNMP v2c for basic network monitoring.
• Understand IP addressing and routing between multiple LANs.
• Verify network connectivity and monitor network devices.
• Identify Packet Tracer limitations for SNMP and Syslog.
• Document lab topology, configurations, and verification steps professionally.
