Using VLANs to increase the number of networks available on 
the appliance
VLANs can be used to segment networks for security purposes, to ease 
administration, or increase bandwidth. VLANs appear as dynamic “Data Ports” 
labeled in the format of: “VLAN DDDD” where the “DDDD” is the ID and is an 
integer up to 4 digits long (VLAN 2, or VLAN 4094 for example). AsyncOS 
supports up to 30 VLANs. Duplicate VLAN IDs are not allowed on an Cisco 
IronPort appliance.
