Hello, We use Cisco Catalyst 3750 switch as small data center (DC)/Core Switch on which nearly 200 VLANs sit, having internet connectivity through a ADSL modem/router.
SVI/RVIs are defined for all these 200 VLANs on the same DC/Core Switch. We have the following requirement: VLAN 1 - 190: should communicate among themselves and to internet VLAN 191: having network address 192.168.1.0/28 should not communicate with any other VLAN except internet To meet this requirement we used the following VACL configuration SW(config)#access-list 100 permit ip 192.168.1.0 0.0.0.15 any SW(config)#vlan access-group XYZ 10 SW(config-access-map)#match ip address 100 SW(config-access-map)#action drop SW(config-access-map)#vlan access-group XYZ 20 SW(config)#vlan filter XYZ vlan-list 1-190 By doing this VLAN 1-190 are not able to contact vlan 191, but to internet and among themselves(vlan 1-190). Hosts in VLAN 191 are not able to contact the hosts in 1-190 VLANs(this is also fine), but hosts in VLAN 191 are contacting the SVI/Gateways of 1-190 VLANs. Is there anything wrong in my VACLs configuration or sequence of ACLs. Any help is greatly appreciated. Thanks in advance Mounika M ### Please consider the environment and print this email only if necessary .
