Information
The order option is relevant in the context of the Policy QoS feature only. See the “Quality of
Service” chapter of the FTOS Configuration Guide for more information.
When you use the log option, CP processor logs details about the packets that match. Depending on
how many packets match the log entry and at what rate, the CP may become busy as it has to log these
packets’ details.
The monitor option is relevant in the context of flow-based monitoring only. See the Chapter 44, Port
Monitoring.
vlan
vlan-id Enter the keyword vlan followed by the VLAN ID to filter traffic associated
with a specific VLAN.
Range: 1 to 4094, 1-2094 for ExaScale (can used IDs 1-4094)
To filter all VLAN traffic specify VLAN 1.
ip-address
Enter an IP address in dotted decimal format (A.B.C.D) as the target IP

Configuration Guide.
