Field Reference
VLAN ACLs (VACLs)
Cisco IOS standard or extended ACLs are configured on router interfaces only, and are applied on routed
packets only. In contrast, Cisco Catalyst switches and Cisco 7600 Series routers can use VLAN ACLs
(VACLs) to control the access of all packets that are bridged within a VLAN or that are routed to or from
a VLAN for VACL capture through a WAN interface. VACLs:
• Are processed in hardware.
• Use Cisco IOS ACLs.
• Ignore any Cisco IOS ACL fields that are not supported in hardware.

Element Description
Available VLANs Displays defined VLANs that are available to be associated with the
object you are configuring.
Note The VLANs that are available will depend on the type of object
you are configuring and other settings defined on the device.
For example, when selecting VLANs to assign to a VLAN
group, the Available VLANs list will only contain VLANs that
have not been assigned to another VLAN group. When
selecting VLANs to assign to a security context, the Available
VLANs list will only contain VLANs that are part of a VLAN
group that has been assigned to the service module you are
configuring.
Add >> button Moves selected VLANs from the Available VLANs list to the Selected
VLANs list.
Remove << button Removes selected VLANs from the Selected VLANs list.
Selected VLANs Displays the selected VLANs.
VLAN Ranges The VLAN ranges entered manually before the selector was opened, if
any.
