Assigning Multifield Classifiers in Firewall Filters to Specify Packet-Forwarding Behavior
(CLI Procedure)
Forwarding class
best-effort
assured-forwarding
expedited-forwarding
network-control
You can configure firewall filters with multifield classifiers to classify packets transiting
a port, VLAN, or Layer 3 interface on a J-EX Series switch.
You specify multifield classifiers in a firewall filter configuration to set the forwarding
class and packet loss priority (PLP) for incoming or outgoing packets. By default, the
data traffic that is not classified is assigned to the
0.
You can specify any of the following default forwarding classes:
Queue
0
1
5
7
To assign multifield classifiers in firewall filters:
Configure the family name and filter name for the filter at the
1.
level, for example:
[edit firewall]
user@switch# set family ethernet-switching
user@switch# set family ethernet-switching filter ingress-filter
Configure the terms of the filter, including the
2.
modifiers as appropriate. When you specify a forwarding class you must also specify
the packet loss priority. For example, each of the following terms examines different
packet header fields and assigns an appropriate classifier and the packet loss priority:
The term
voice-traffic
class
expedited-forwarding
[edit firewall family ethernet-switching filter ingress-filter]
user@switch# set term voice-traffic from vlan-id voice-vlan
user@switch# set term voice-traffic then forwarding-class expedited-forwarding
user@switch# set term voice-traffic then loss-priority low
The term data-traffic
class
assured-forwarding
[edit firewall family ethernet-switching filter ingress-filter]
user@switch# set term data-traffic from vlan-id employee-vlan
user@switch# set term data-traffic then forwarding-class assured-forwarding
user@switch# set term data-traffic then loss-priority low
best-effort
