Hi all,
I have a Catalyst 6509 and a 3524XL(12.0(5.3)WC(1).
They are conneted with each other through TRUNK (ISL) .
The Cat3524 have two Vlans .Default Vlan is for Management. and the other is for users
I applyed an ACL on vlan 1 to block spoofing IP address, and the communication was disconnected.
Question is, How Can I apply the ACL in the Cat3524XL to block some spoofing IP Address ?
and Is that possible ?
The configuration is..
interface FastEthernet0/22
switchport access vlan 3
!
interface FastEthernet0/23
switchport access vlan 3
!
interface FastEthernet0/24
!
interface GigabitEthernet0/1
switchport trunk encapsulation dot1q
switchport mode trunk
!
interface VLAN1
ip address 192.168.1.1 255.255.255.0
no ip directed-broadcast
no ip route-cache
ip access-list 100 in
!
access-list 100 permit ip 192.168.1.0 0.0.0.255 any
access-list 100 deny ip any any log
Thanks in advance
