How to configure an IP access list to control directed broadcasts for the Wake-on-LAN setup.
In order to configure an IP access list to control directed broadcasts, complete one of these steps:
Step 1:
Configure the ip directed-broadcast command directly on an interface:
| Hostname(config)#interface FastEthernet Hostname(config-if)#ip directed-broadcast |
Step 2:
Configure an access control list (ACL) in order to permit traffic only from a trusted source.
For example, 192.168.10.10 is the Wake-on-LAN (WoL) server.
| Hostname(config)#access-list 10 permit 192.168.10.10 |
Then, apply that under the VLAN interface:
| Hostname(config)#interface Vlan Hostname(config-if)#ip address x.x.y.y subnet mask Hostname(config-if)#no ip redirects Hostname(config-if)#ip directed-broadcast 10 !--- 10 is the ACL number. |
