-====== Cisco Switches ====== 
- 
-===== VLANs ===== 
- 
-To show the VLANs and port assignments:​ show vlan brief 
- 
-===== Trunk ports ===== 
- 
-If you're not sure which interfaces are set to trunk or not, try: 
- 
-<​code>​show interfaces trunk module 1</​code>​ 
- 
-Show which VLANs are allowed on the trunk port: 
- 
-<​code>​show interfaces gigabitEthernet 1/0/24 trunk</​code>​ 
- 
-If you want to specify which VLANs are allowed on the trunk port: 
- 
-<​code>​ 
-int gi1/0/24 
-switchport trunk allowed vlan 1,​100</​code>​ 
- 
-<WRAP center round help 60%> 
-But if you don't specify, then it will allow all VLANs. (I think... but this is not confirmed) 
-</​WRAP>​
