55.3 VLAN-ACL Configuration Example
A company’s network configuration is as follows, all departments are divided by different VLANs, technique
department is Vlan1, finance department is Vlan2. It is required that technique department can access the
outside network at timeout, but finance department are not allowed to access the outside network at any time
for the security. Then the following policies are configured:
 Set the policy VACL_A for technique department. At timeout they can access the outside network,
the rule as permit, but other times the rule as deny, and the policy is applied to Vlan1.
 Set the policy VACL_B of ACL for finance department. At any time they can not access the outside
network, but can access the inside network with no limitation, and apply the policy to Vlan2.
Network environment is shown as below:
Figure 10-1 VLAN-ACL configuration example
Configuration example:
1) First, configure a timerange, the valid time is the working hours of working day:
Switch(config)#time-range t1
Switch(config-time-range-t1)#periodic weekdays 9:00:00 to 12:00:00
Switch(config-time-range-t1)#periodic weekdays 13:00:00 to 18:00:00
2) Configure the extended acl_a of IP, at working hours it only allows to access the resource within the
internal network (such as 192.168.0.255).
Switch(config)# ip access-list extended vacl_a
Switch(config-ip-ext-nacl-vacl_a)# permit ip any-source 192.168.0.0 0.0.0.255 time-range t1
Switch(config-ip-ext-nacl-vacl_a)# deny ip any-source any-destination time-range t1
