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 81: 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.
Define the IP ACL that will match the correct packets.
Switch(config)#
ip access-list extended SERVER1_ACL
Switch(config-ext-nacl))#
permit ip 10.1.2.0 0.0.0.255 host 10.1.1.100
Switch(config-ext-nacl))#
permit ip host 10.1.1.4 host 10.1.1.100
Switch(config-ext-nacl))#
permit ip host 10.1.1.8 host 10.1.1.100
Switch(config-ext-nacl))#
exit
Define a VLAN map using this ACL that will drop IP packets that match SERVER1_ACL and forward IP
packets that do not match the ACL.
Switch(config)#
vlan access-map SERVER1_MAP
Switch(config-access-map)#
match ip address SERVER1_ACL
Switch(config-access-map)#
action drop
