Cisco Terminal

Notes

Any commands that alter how the device functions requires the 'enable' command to be run prior.

If you do not save the running config, all changes made will be reset on power off.

Configuring ranges - If a command asks for an [interface-id] you may replace that with 'range [interface][start id]-[end id]' eg: interface range gi1/0/1-24

Shortcuts

• enable = en
• show = sh
• configure = config
• terminal = ter
• interface = int
• gigabitethernet1/0/1 = gi1/0/1
