Time Based ACL

[Robyn]

Hi guys, so I have 10 IPs to deny them from using the internet during office hours (0900 - 1800) on weekdays. These IPs are from different VLANs. How do I go about configuring them?
ip dhcp excluded-address 192.168.20.11
ip dhcp excluded-address 192.168.20.12
ip dhcp excluded-address 192.168.20.13
ip dhcp excluded-address 192.168.20.14
ip dhcp excluded-address 192.168.30.9
ip dhcp excluded-address 192.168.30.10
ip dhcp excluded-address 192.168.30.11
ip dhcp excluded-address 192.168.30.12
ip dhcp excluded-address 192.168.30.13
ip dhcp excluded-address 192.168.30.14

These are the IPs that I have excluded from DHCP so I can configure them to not use the internet during office hours. 

192.168.20.0 has a subnet of /28 VLAN20

192.168.30.0 has a subnet of /28 as well VLAN30

So how do I configure them as I've been having a lot of troubles with it

Hi thanks for the response! I've checked it but the problem is the IPs that I've excluded how am I going to put them in a subnet range? 

[Joseph W. Doherty]

One option would be to go to each PC and statically define the IP you want it to use.

Another option, which your DHCP server might offer, is to assign specific IPs based on client's MAC.

For either approach, you just insure the IPs are in the subnets they need to be (and, of course, not used by any other device).

[Robyn]

Yes ive statically assigned them the ip addresses but I dont see how I can create a time range access list for them 

[Joseph W. Doherty]

Sorry mistook your questions about getting hosts, with known IPs, to time manage.

Just to be sure, these devices should be allowed to access the internet in off hours?  (1800-0900).

[Robyn]

Yes they should be allowed during off hours

During Weekdays, can you more elaborate?
