本篇文章给大家分享的是有关ACL中命名访问控制列表是怎样的,小编觉得挺实用的,因此分享给大家学习,希望大家阅读完这篇文章后可以有所收获,话不多说,跟着小编一起来看看吧。
实验拓扑图及实验要求
实验步骤:
一、配置sw交换机
conf t //进入全局模式,设定vlan10 和20
vlan 10,20
ex
do show vlan-sw b //查看vlan信息
VLAN Name Status
10 VLAN0010 active
20 VLAN0020 active
int range fa1/1 -2 //进入端口fa1/1和1/2 接口,将端口划入vlan10
sw mo acc
sw acc vlan 10
ex
do show vlan-sw b //查看vlan信息
VLAN Name Status Ports
10 VLAN0010 active Fa1/1, Fa1/2
20 VLAN0020 active
int f1/3 //进入端口f1/3,将端口划入vlan20
sw mo acc
sw acc vlan 20
ex
do show vlan-sw b
VLAN Name Status Ports
10 VLAN0010 active Fa1/1, Fa1/2
20 VLAN0020 active Fa1/3
int f1/0 //进入端口f1/0,配置trunk链路
sw mo t
sw t en dot1q
ex
no ip routing //关闭路由功能
二、配置sw-3三层交换机
conf t
no switchport //关闭交换功能
int f1/1
ip add 192.168.100.1 255.255.255.0
no shut
ex
vlan 10,20
ex
int vlan 10
ip add 192.168.10.1 255.255.255.0
no shut
ex
int vlan 20
ip add 192.168.20.1 255.255.255.0
no shut
ex
do show ip int b //查看vlan信息
FastEthernet1/1 192.168.100.1 YES manual up up
Vlan10 192.168.10.1 YES manual up down
Vlan20 192.168.20.1 YES manual up down
int f1/0 //进入端口f1/0配置trunk链路
sw mo t
sw t en dot1q
do show ip route //查看路由表
C 192.168.10.0/24 is directly connected, Vlan10
C 192.168.20.0/24 is directly connected, Vlan20
C 192.168.100.0/24 is directly connected, FastEthernet1/1
三、配置客户机ip地址,并测试全网互通性
1、配置客户机ip地址
PC1> ip 192.168.100.100 192.168.100.1
Checking for duplicate address...
PC1 : 192.168.100.100 255.255.255.0 gateway 192.168.100.1
PC2> ip 192.168.10.10 192.168.10.1
Checking for duplicate address...
PC1 : 192.168.10.10 255.255.255.0 gateway 192.168.10.1P
C3> ip 192.168.10.20 192.168.10.1
Checking for duplicate address...
PC1 : 192.168.10.20 255.255.255.0 gateway 192.168.10.1
PC4> ip 192.168.20.20 192.168.20.1
Checking for duplicate address...
PC1 : 192.168.20.20 255.255.255.0 gateway 192.168.20.1
2、测试全网互通性
四、配置命名acl、策略
在sw-3交换机上进行配置,全局模式下
ip access-list standard yun //设定模式以及命名名称,standard为标准命名ACL,extended为扩展命名ACL
permit host 192.168.10.10 //设定允许访问主机ip的条目
deny 192.168.10.0 0.0.0.255 //设定拒绝的网段条目
permit any //设顶允许其他所有主机访问
ex
do show access-list //查看访问列表清单
Standard IP access list yun
10 permit 192.168.10.10
20 deny 192.168.10.0, wildcard bits 0.0.0.255
30 permit any
int f1/1 //进入端口f1/1,将ACL应用与此出方向
ip access-group yun out
五、测试acl效果
1、测试vlan10中的主机2与主机1的互通性
PC2> ping 192.168.100.100
192.168.100.100 icmp_seq=1 timeout
192.168.100.100 icmp_seq=2 timeout
84 bytes from 192.168.100.100 icmp_seq=3 ttl=63 time=15.953 ms
84 bytes from 192.168.100.100 icmp_seq=4 ttl=63 time=19.232 ms
84 bytes from 192.168.100.100 icmp_seq=5 ttl=63 time=19.049 ms
2、测试主机4与主机1的互通性
PC4> ping 192.168.100.100
84 bytes from 192.168.100.100 icmp_seq=1 ttl=63 time=20.226 ms
84 bytes from 192.168.100.100 icmp_seq=2 ttl=63 time=18.953 ms
84 bytes from 192.168.100.100 icmp_seq=3 ttl=63 time=18.208 ms
84 bytes from 192.168.100.100 icmp_seq=4 ttl=63 time=17.023 ms
84 bytes from 192.168.100.100 icmp_seq=5 ttl=63 time=12.985 ms
3、测试vlan10中的其他主机与主机1的互通性
PC3> ping 192.168.100.100
*192.168.10.1 icmp_seq=1 ttl=255 time=8.907 ms (ICMP type:3, code:13, Communication administratively prohibited)
*192.168.10.1 icmp_seq=2 ttl=255 time=3.775 ms (ICMP type:3, code:13, Communication administratively prohibited)
*192.168.10.1 icmp_seq=3 ttl=255 time=7.979 ms (ICMP type:3, code:13, Communication administratively prohibited)
*192.168.10.1 icmp_seq=4 ttl=255 time=5.965 ms (ICMP type:3, code:13, Communication administratively prohibited)
*192.168.10.1 icmp_seq=5 ttl=255 time=1.992 ms (ICMP type:3, code:13, Communication administratively prohibited)
命名访问控制列表可灵活的调整策略前提是在标准访问列表以及扩展访问列表的基础上,可以使用no+ACL号删除策略.也可以使用ACL号+permittip追加ACL策略
