最佳答案
就是packet-filter 3000 inbound 或者outbound

必然是三层接口 interface GigabitEthernet1/0/3 port link-mode route combo enable copper ip address 10.10.10.2 255.255.255.248 ospf bfd enable bfd min-transmit-interval 500 bfd min-receive-interval 500 bfd detect-multiplier 3 #

进入端口下调用即可,前提端口是三层口。
以下是参考命令:
1、创建ACL,对高危端口进行拦截:
acl number 3210
rule 0 deny tcp destination-port eq 135
rule 1 deny udp destination-port eq 135
rule 2 deny tcp destination-port eq 137
rule 3 deny udp destination-port eq netbios-ns
rule 4 deny tcp destination-port eq 138
rule 5 deny udp destination-port eq netbios-dgm
rule 6 deny udp destination-port eq netbios-ssn
rule 7 deny tcp destination-port eq 139
rule 8 deny tcp destination-port eq 445
rule 9 deny udp destination-port eq 445
rule 10 deny tcp destination-port eq 3389
rule 11 deny udp destination-port eq 3389
rule 20 deny tcp source-port eq 135
rule 21 deny udp source-port eq 135
rule 22 deny tcp source-port eq 137
rule 23 deny udp source-port eq netbios-ns
rule 24 deny tcp source-port eq 138
rule 25 deny udp source-port eq netbios-dgm
rule 26 deny udp source-port eq netbios-ssn
rule 27 deny tcp source-port eq 139
rule 28 deny tcp source-port eq 445
rule 29 deny udp source-port eq 445
rule 30 deny tcp source-port eq 3389
rule 31 deny udp source-port eq 3389
rule 1500 permit ip
2、将ACL下发到端口:
int range gi 1/0/1 gi 1/0/24
packet-filter 3210 inbound
packet-filter 3210 outbound
quit
