最佳答案
把下面的端口改成你想封掉的即可
acl advanced 3010
description deny_445
rule 0 permit tcp destination-port eq 445
rule 5 permit tcp destination-port eq 135
rule 10 permit tcp destination-port eq 137
rule 15 permit tcp destination-port eq 138
rule 20 permit tcp destination-port eq 139
#
traffic classifier deny_445 operator and
if-match acl 3010
#
traffic behavior deny_445
accounting packet
filter deny
#
qos policy deny_445
classifier deny_445 behavior deny_445
#
qos apply policy deny_445 global inbound // 全局调用策略
(0)
说错了,是交换机的具体端口,应该怎么设置呢
具体关口是物理端口吗 还是通信端口
是交换机的物理端口
这个限制不了
您好,请知:
可以使用高级ACL来对端口进行拦截,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:
interface Ten-GigabitEthernet 1/1/1
packet-filter 3210 inbound
packet-filter 3210 outbound
quit
