switch vlan調整

• 耍笨：把自己關在switch外的方法
  • 把進線port關掉、mode換掉(eg. hybrid換trunk，某些switch會洗掉所有tag設定)
  • vlan ip interface設了但default gateway沒設
  • 有兩個default gateway，switch自己選那個錯的，所以連線不穩定
• dlink firmware download http://ftp.dlink.ru/pub/Switch/
• 頭痛的vlan

• 命名規則
  • 新switch HCSH-A3F-NL2-001ST3；A棟3樓－新L2－001號，堆疊3部
  • 舊switch HCSH-D5F-OL2-003；D棟5樓－舊L2－3號
  • 舊HUB HCSH-D5F-OL2-hub-3；D棟5樓－舊L2－無網管－3號
