华为acl(traffic-filter)和dhcp管理

华为alc配置实例:-traffic-filter

# 在VLAN100上配置基于ACL的报文过滤，允许源IP地址为192.168.0.2/32的报文通过，丢弃其他报文。

<HUAWEI> system-view

[HUAWEI] vlan 100

[HUAWEI-vlan100] quit

[HUAWEI] acl name test 3000

[HUAWEI-acl-adv-test] rule 5 permit ip source 192.168.0.2 0

[HUAWEI-acl-adv-test] rule 10 deny ip source any

[HUAWEI-acl-adv-test] quit

[HUAWEI] traffic-filter vlan 100 inbound acl name test

 

traffic-filter实例:

int vlan15

acl name wifiToServer 3000

rule 5 per ip so 192.168.5.95 0

rule 10 per ip so 192.168.5.139 0

rule 15 per ip so 192.168.5.165 0

rule 20 per ip so 192.168.5.212 0

rule 25 per ip so 192.168.5.241 0

rule 30 per ip so 192.168.5.242 0

 

traffic-filter vlan 15 inbound acl name wifiToServer

 

dhcp地址池配置:

interface Vlanif100

ip address 192.168.100.1 255.255.255.0

dhcp select interface

dhcp server static-bind ip-address 192.168.100.241 mac-address 28f0-7647-11fd

dhcp server static-bind ip-address 192.168.100.242 mac-address fcc2-deef-408c

dhcp server static-bind ip-address 192.168.100.243 mac-address 00ee-bd87-d99a

dhcp server static-bind ip-address 192.168.100.244 mac-address 7423-448d-12e9

dhcp server static-bind ip-address 192.168.100.245 mac-address cc08-8db5-05aa

dhcp server static-bind ip-address 192.168.100.56 mac-address 0008-caa2-1aa3

dhcp server excluded-ip-address 192.168.20.100 192.168.20.120

 

dhcp ip是否被分配:

dis ip pool interface Vlanif15 used | include fcc2-deef-4080 192.168.5.241

 

dhcp释放used地址:

reset ip pool int vlanif20 x.x.x.x

 

dhcp释放conflict ip:

reset ip pool int vlanif20 conflict ßconflict ip是无法被分配的,也无法在used里查到,也无法在借口绑定给用户,查看冲突ip: dis ip pool intterface vlan 100 conflict

 

dhcp地址池绑定ip

reset ip pool int vlanif15 192.168.5.56 ß如果已被分配了,为确保最小震荡,先释放,后绑定.
