  1. Cisco Lab 2012-09-17

  2. 大綱 • Switch 交換器原理(Hub、Switch) • Hub：LAB-1 • Switch：LAB-2 • 基本操作 • EXEC&Show：LAB-3 • Configure：LAB-4

  3. 大綱 • Layer 2：Single-LAN • Single-LAN：LAB-5 • Layer 2：Multi-LAN • Multi-LAN：LAB-6 • Homework – 1 • Homework – 2

  4. Switch 交換器原理 • Address Learning • MAC Address Table • Aging time • Packet Forwarding / Filtering

  5. Dynamic MAC Address - Broadcast A C 0260.8c01.1111 0260.8c01.3333 E1 E3 E4 E2 D B 0260.8c01.2222 0260.8c01.4444

  6. Dynamic MAC Address - Broadcast A C 0260.8c01.1111 0260.8c01.3333 E1 E3 E4 E2 D B 0260.8c01.2222 0260.8c01.4444

  7. DynamicMAC Address - ARP MAC Address Table E1:0260.8c01.1111 A C E1 E3 Host A ARP E4 E2 D B Host B ARP 0260.8c01.1111 192.168.1.1

  8. Dynamic MAC Address - ARP MAC Address Table E1:0260.8c01.1111 A C E2:0260.8c01.2222 E1 E3 Host A ARP E4 E2 192.168.1.2 0260.8c01.2222 D B Host B ARP 0260.8c01.1111 192.168.1.1

  9. 基本操作 • EXEC Session • User EXEC Level • Privileged EXEC Level • Configuration Mode • Show • Configuration • save

  10. 基本操作 - EXEC Session • Step 1 : Switch> • Step 2 : Switch>enable • Step 3 : Switch#configure terminal • Step 4 : Switch(config)#

  11. 基本操作 - Show • show ? • show version • show ver + [tab] • Show ver • show running-config / startup-config • show mac address-table • show interface ?

  12. 基本操作 - Show • show user • show history • Ctrl-p / up-arrow key • Ctrl-n / down arrow key • show clock • show logging

  13. 基本操作 - Configuration • Hostname • Time • Clock set • NTP (Timezone / NTP Server) • Interface • Shutdown / No Shutdown • Set IP Address

  14. 基本操作 - Configuration • Console / VTY • Password (login / enable) • Password Encryption • Default Gateway • Domain Name System • (no) ip domain-lookup • ip name-server

  15. Single-LAN Mac Address Table Mac Address Table E1: 260.8c01.1111 E1: 260.8c01.1111 E3 E1 E3 E1 E2 E4

  16. Single-LAN Mac Address Table Mac Address Table E1: 260.8c01.1111 E1: 260.8c01.1111 E3: 260.8c01.4444 E4: 260.8c01.4444 E3 E1 E3 E1 E2 E4

  17. Multi-LAN • VLAN (Virtual Local Area Network) • Trunk • VTP Mode

  18. Multi-LAN - VLAN VLAN 1 VLAN 3 VLAN 2

  19. Homework - 1 • 使用HW-1.pkt • 設定Switch Hostname • 與Lab上switch名稱相同 • Password • Con0、VTY：cisco • Enable：CISCO • 密碼需加密 • 新增VLAN • VLAN 99 • VLAN Name：VLAN_99 • 管理用VLAN，IP請自訂，但MNG-1設備必須能telnet到Switch進行管理 • VLAN 10、VLAN 11 • VLAN Name：VLAN_10、VLAN_11 • PC0、PC1、PC2在VLAN_10 • PC3、PC4、PC5在VLAN_11

  20. Homework - 2 • 使用HW-2.pkt • 請先使用PING測試各PC間的連線 • 請再加上一條跳線連接Switch0及Switch1 • 再次使用PING測試各PC間的連線 • 使用模擬器的Simulation觀察封包的流向 • 請說明是什麼原因造成在多接上一條線後會造成PC間無法連線?
