Cisco CatOS based switches

Creating VLANs on CatOS is a little different, though the terminology is the same as using VLANs under IOS. Standalone VLANs and VTP are both possible to maintain the VLAN database:

# set vtp domain example mode server # set vtp passwd SuperSecret
# set vlan 10 name dmz
# set vlan 20 name phones

Then configure a trunk port to automatically handle every VLAN:

# set trunk 5/24 on dot1q 1-4094

Then add ports to the VLAN:

# set vlan 10 5/1-8 # set vlan 20 5/9-15
