第一步：创建ACL
ip access-list extended test-down-in
 10 permit icmp host 172.31.13.220 host 172.31.13.1
 20 permit icmp host 172.31.13.1  host 172.31.13.220
 100 permit ip any any 
!
ip access-list extended test-down-out
 10 permit icmp host 172.31.13.220 host 172.31.13.1
 20 permit icmp host 172.31.13.1  host 172.31.13.220
 100 permit ip any any 
!
ip access-list extended test-up-in
 10 permit icmp host 172.31.13.220 host 172.31.13.1
 20 permit icmp host 172.31.13.1  host 172.31.13.220
 100 permit ip any any 
!
ip access-list extended test-up-out
 10 permit icmp host 172.31.13.220 host 172.31.13.1
 20 permit icmp host 172.31.13.1  host 172.31.13.220
 100 permit ip any any 
 
 第二步：开启ACL计数
 !
ip access-list counter test-up-in
!         
ip access-list counter test-up-out
!
ip access-list counter test-down-out
!
ip access-list counter test-down-in

第三步：
上下联口调用ACL：
上联口：
ip access-group test-up-in in
ip access-group test-up-out out

下连口：
ip access-group test-down-in in
ip access-group test-down-out out


清楚计数命令：
Ruijie#clear counters access-list
