VLANs can be used to segment networks for security purposes, to ease
administration, or increase bandwidth. For example, create multiple VLANs on
the P1 interface and then apply different policies to each. 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 IronPort appliance.
