+## On Boot
+Press **Enter** to begin
+
+If greeted with a prompt asking about *Initial Configuration Dialogue*, type `n` and hit enter.
+- If you decide to make use of Initial Configuration, refer to [Cisco Docs](https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/fundamentals/configuration/15mt/fundamentals-15-mt-book/cf-setup.html)
+
+You should be greeted with a prompt that has a `>` character at the end, indicating you are in user EXEC mode. This is limited and not used for configuration.
+
+Enable privileged EXEC mode to get access to all commands and configurations:
+```
+enable
+```
+Shorthand: `ena`
+
+
+Enter configuration mode, configuring from the terminal (also possible to configure from memory or the network):
+```
+configure terminal
+``` 
+Shorthand: `conf t`
+
+## Create/edit a vlan
+[docs](https://community.cisco.com/t5/networking-knowledge-base/how-to-configure-vlans-on-the-catalyst-switches/ta-p/3131780)
+From configuration mode:
+```
+vlan [vlan-id]
+```
+where `[vlan-id]` is the vlan number you want to generate, this will put you into config-vlan mode
+
+## Assign a vlan a name
+From `config-vlan` mode:
+```
+name [ascii name]
+```
+where `[ascii name]` is the name you want to assign (EG: `Accounting`)
+## Assign interfaces to a vlan
+[docs](https://community.cisco.com/t5/networking-knowledge-base/how-to-configure-vlans-on-the-catalyst-switches/ta-p/3131780)
+Enter interface config mode (from conf mode):
+Single port:
+```
+interface [interface-to-configure]
+```
+shorthand: `int [interface-to-configure]`
+Range [docs](https://www.cisco.com/c/en/us/td/docs/ios/interface/configuration/guide/ir_ifrange.html):
+```
+interface range fa0/st - nd
+```
+where `fa` is the speed, `st` the starting port, and `nd` the end port
+
+From `config-if` mode:
+Enter port mode configuration:
+```
+switchport mode access
+```
+
+Link the interface(s) to a vlan:
+```
+switchport access vlan [vlan-id]
+```
+
+interfaces are referenced in the format of `sp0/nm` where speed and port number are specified (eg: fa0)
+
+## Configuring trunk ports
+From the `config` mode, select an interface to configure as trunk mode:
+```
+interface [interface-id (sp0/nm syntaax)]
+```
+shorthand: `int fa0/nm`
+
+Set the mode of the selected interface to trunk mode:
+```
+switchport mode trunk
+```
+
+
+Type `end` or `exit` to leave `config-if` mode
+
+## Limiting trunk traffic to a specific vlan
+From `config` mode:
+```
+interface [interface-id]
+```
+shorthand: `int fa0/24`
+
+Change trunk config:
+```
+switchport trunk allow vlan [vlan-id]
+```
+
+## Force vlans to be online:
+From `configure` mode:
+```
+vlan [vlan-id]
+```
+- [ ] 
+```
+no shutdown
+```
+
+# Viewing configs
+### Vlan config
+From the privileged exec terminal: 
+```
+show vlan
+```
+
+### See what IP address is assigned to a vlan
+From privileged exec mode:
+```
+show run int vlan [vlan-id]
+```
+
+See what mode an interface is in:
+```
+show int [interface] switchport
+```
+
+### interface trunk config
+From privileged exec:
+```
+show interface trunk
+```
