Switch(config-ext-nacl)# exit
Next, create VLAN access map map2 so that traffic that matches the http access list is dropped and all other
IP traffic is forwarded.
Switch(config)# vlan access-map map2 10
Switch(config-access-map)# match ip address http
Switch(config-access-map)# action drop
Switch(config-access-map)# exit
Switch(config)# ip access-list extended match_all
Switch(config-ext-nacl)# permit ip any any
Switch(config-ext-nacl)# exit
Switch(config)# vlan access-map map2 20
Switch(config-access-map)# match ip address match_all
Switch(config-access-map)# action forward
Then, apply VLAN access map map2 to VLAN 1.
Switch(config)# vlan filter map2 vlan 1
Example: Restricting Access to a Server on Another VLAN
You can restrict access to a server on another VLAN. For example, server 10.1.1.100 in VLAN 10 needs to
have access denied to these hosts:
•
Hosts in subnet 10.1.2.0/8 in VLAN 20 should not have access.
•
Hosts 10.1.1.4 and 10.1.1.8 in VLAN 10 should not have access.
Figure 8: Restricting Access to a Server on Another VLAN
Example: Denying Access to a Server on Another VLAN
This example shows how to deny access to a server on another VLAN by creating the VLAN map SERVER
1 that denies access to hosts in subnet 10.1.2.0.8, host 10.1.1.4, and host 10.1.1.8 and permits other IP traffic.
The final step is to apply the map SERVER1 to VLAN 10.
