Creating VLAN ID Ranges for Layer 2 
Networks
If the network uses VLAN ID tags, you have the option of creating policies that select traffic with 
specific VLAN ID tags or within a range of VLAN ID tags. If you do not include VLAN ID tags in a 
new Layer 2 policy, the policy is applied to all network traffic. 
VLAN ID tags are used to create logical networks within a larger physical network. This is often used to 
separate network traffic by departments, such as Finance or Human Resources. By creating policies that 
act on specific VLAN ID tags or a range of VLAN ID tags, you can encrypt, pass in the clear, or drop 
traffic at the logical level (in this case by department). Traffic that does not match the VLAN ID tag (or 
range of tags) specified in the policy is dropped. 
ETEP PEPs accept only single VLAN ID tags in policies
.
