Step 3 Run:
tcp aging-time aging-time
The aging time of the TCP traffic forwarding table is set.
By default, the aging time of the TCP traffic forwarding table is 3600s.
Step 4 Run:
udp aging-time aging-time
The aging time of the UDP traffic forwarding table is set.
By default, the aging time of the UDP traffic forwarding table is 120s.

6.3.10 Configuring a Layer 3 Classifier

This section describes how to create a Layer 3 classifier and configure a matching rule.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
load-balance l3classifier l3classifier-name
A Layer 3 classifier is created and the Layer 3 classifier view is displayed.
By default, no Layer 3 classifier is created.
Step 3 Run:
if-match acl acl-number
An ACL is bound to the Layer 3 classifier.
A Layer 3 classifier can be bound to only one ACL. If the if-match acl acl-number command
is run for multiple times in the same Layer 3 classifier view, the latest configuration takes effect.
By default, no ACL is bound to a Layer 3 classifier.
Step 4 Run:
l7classifier l7classifier-name action action-name
The Layer 7 classifier and action are bound to the Layer 3 classifier.
The SPU first matches packets with the ACL in a Layer 3 classifier, and then matches packets
with the rule in a Layer 7 classifier.
By default, a Layer 3 classifier is not bound to any Layer 7 classifier and action.
Step 5 (Optional) Run:
icmp-reply
The SPU is configured to respond ping requests of users.
In egress link load balancing, if the SPU is required to respond to ping requests of users, you
need to use the icmp-reply command.
