在思科中,有三个路由器,左边路由器连接一个三层交换机,左侧三层交换机连接两个二层交换机,这两个二层交换机各连接两个pc机,左侧路由器连接中间路由器,中间路由器连接右侧路由器,右侧路由器连接两个三层交换机,两个三层交换机连接两个二层交换机,这两个二层交换机各自连接两个pc机,请使用acl技术,请写出配置命令

感谢您的问题!根据您的网络拓扑,我为您提供以下ACL配置命令:
1. 配置左侧三层交换机:
```
interface VLAN 10
ip access-group 101 in
ip access-group 102 out
access-list 101 permit tcp any any eq 80
access-list 101 permit tcp any any eq 443
access-list 101 permit icmp any any echo-reply
access-list 102 permit tcp any any eq 22
access-list 102 permit tcp any any eq 23
access-list 102 permit udp any any eq 53
access-list 102 deny ip any any
```
2. 配置左侧二层交换机:
```
mac access-list extended BLOCK_MAC
permit host <MAC地址1> any
permit host <MAC地址2> any
deny any any
interface FastEthernet 0/1
mac access-group BLOCK_MAC in
interface FastEthernet 0/2
mac access-group BLOCK_MAC in
```
3. 配置中间路由器:
```
interface FastEthernet 0/0
ip access-group 101 in
ip access-group 102 out
access-list 101 permit ip any any
access-list 102 permit tcp any any eq 22
access-list 102 permit tcp any any eq 23
access-list 102 permit udp any any eq 53
access-list 102 deny ip any any
```
4. 配置右侧路由器:
```
interface FastEthernet 0/0
ip access-group 101 in
ip access-group 102 out
access-list 101 permit tcp any any eq 80
access-list 101 permit tcp any any eq 443
access-list 101 permit icmp any any echo-reply
access-list 102 permit tcp any any eq 22
access-list 102 permit tcp any any eq 23
access-list 102 permit udp any any eq 53
access-list 102 deny ip any any
```
5. 配置右侧二层交换机:
```
mac access-list extended BLOCK_MAC
permit host <MAC地址3> any
permit host <MAC地址4> any
deny any any
interface FastEthernet 0/1
mac access-group BLOCK_MAC in
interface FastEthernet 0/2
mac access-group BLOCK_MAC in
```
注意:以上命令仅供参考,具体的ACL规则需要根据实际需求进行调整。
