Step 6 — Connect SW1 to SW3 (Access switch B)

What this link is

• Distribution → Access
• Same role as SW2, just the second access block

---

Exactly what to use

• Cable: Copper Straight-Through

Exactly which ports

• SW1 → GigabitEthernet0/3 (If no more Gigabit ports, use updated section 6 below)
• SW3 → GigabitEthernet0/1

---

Click-by-click

1. Click Connections (⚡)
2. Select Copper Straight-Through
3. Click SW1 → Gi0/3
4. Click SW3 → Gi0/1

Stop.

What you should see

• Amber → Green after a few seconds
• If it stays amber briefly, that’s normal

---

Do NOT do yet

❌ No second uplink
❌ No EtherChannel
❌ No VLANs

🔹 UPDATED STEP 6 — Connect SW1 to SW3 (using FastEthernet)

Cable

• Copper Straight-Through

Ports (IMPORTANT)

• SW1 → FastEthernet0/23
• SW3 → FastEthernet0/1

---

Click-by-click

1. Click Connections (⚡)
2. Choose Copper Straight-Through
3. Click SW1
4. Select FastEthernet0/23
5. Click SW3
6. Select FastEthernet0/1

Stop.

Why this is OK (1 sentence)

CCNA tests logic and concepts, not port speeds — VLANs, trunks, STP work exactly the same on FastEthernet.

---

Very important (so you don’t worry later)

• We can still:
  • do VLAN trunks
  • run STP
  • show redundant paths
• EtherChannel later may use FastEthernet instead of Gigabit — still valid for CCNA.

✅ Short answer

Port speed does NOT limit CCNA practice.
FastEthernet vs Gigabit makes no difference to CCNA topics.
