Switch Configuration & Troubleshooting

Role: Access and trunk VLANs for on-prem workstations and uplink

Hostname: AKWAA-SW

Troubleshooting Checklist

Layer 1: Physical & Cable Checks

• [ ] Check LEDs and link lights on all ports.
• [ ] Verify cables for damage or incorrect type; swap cables or ports if a link is down.
• [ ] Check SFP modules (if used): Ensure they are Cisco-supported and properly seated.
• [ ] Reseat SFP modules if needed.

Layer 2: Interface & VLAN Status

• [ ] Check interface status: Ports should be “connected” or “up.”

• [ ] Check VLAN assignments:

  • User ports (Gi0/0–Gi0/2) → VLAN 10

  • Uplink (Gi0/3) → Trunk, allowing all needed VLANs

• [ ] Verify trunking: Uplink should allow VLANs 10 and 99, with correct native VLAN.

• [ ] Check SVI status: Should be “up/up.”

  • If down, ensure at least one port in VLAN 99 is up.

Layer 3: Management & Connectivity

• [ ] Ping the switch’s management IP from the Core Router or a VLAN 99 device.
• [ ] Check ARP table to confirm Layer 3 reachability.
