由于业务流量不断增大，导致 6604的内存占用不断升高，为避免由路由器内存占用过大影响设备整体性能，对路由器的会话参数做了以下调整。

调整前：

[XXXX6604]dis session aging-time
 Protocol                 Aging-time(s)
 syn                      30
 tcp-est                  3600
 fin                      30
 udp-open                 30
 udp-ready                60
 icmp-open                60
 icmp-closed              30
 rawip-open               30
 rawip-ready              60
 accelerate               10

调整参数

system

 session aging-time syn 10
  session aging-time tcp-est 10
  session aging-time fin 10
  session aging-time udp-open 10
  session aging-time udp-ready 20
  session aging-time icmp-open 20
  session aging-time icmp-closed 10
  session aging-time rawip-open 30
  session aging-time rawip-ready 60
  session aging-time accelerate 10
 
调整后 
[XXXX6604]display session aging-time
 Protocol                 Aging-time(s)
 syn                      10
 tcp-est                  10
 fin                      10
 udp-open                 10
 udp-ready                20
 icmp-open                20
 icmp-closed              10
 rawip-open               30
 rawip-ready              60
 accelerate               10
