•
Set the forwarding class of incoming packets. The forwarding class determines the
output queue.
user@host# set term term-name then forwarding-class class-name
•
Set the loss priority of incoming packets. The loss priority is used by schedulers in
conjunction with the random early discard (RED) algorithm to control packet discard
during periods of congestion.
user@host# set term term-name then loss-priority (high | low | medium-high |
medium-low)
To configure a simple filter:
1. Specify a name for the simple filter.
[edit firewall family family-name]
user@host# edit simple-filter filter-name
2. Specify the term name and match criteria you want to look for in incoming packets.
[edit firewall family family-name simple-filter filter-name]
user@host# set term term-name from match-conditions
3. Specify the action you want to take when a packet matches the conditions.
[edit firewall family family-name simple-filter filter-name]
user@host# set term term-name then actions
For multifield classifiers, you can perform the following actions for a simple filter:
•
Set the forwarding-class of incoming packets.
•
Set theloss-priority of incoming packets.
To apply the firewall filter to the appropriate logical interfaces as an input filter.
1. Specify the physical and logical interface on which you want to apply the firewall filter.
edit
user@host# edit interfaces interface-name unit unit-number
2. Specify the protocol family for the firewall filter.
[edit interfaces interface-name unit unit-number]
user@host# set family family-name
3. Specify the names of the firewall filters to apply to received packets.
[edit interfaces interface-name unit unit-number]
user@host# set filter input filter-name
Repeat this step for the family protocol filter and the simple filter.
4. Save your configuration.
