Information

When the CSS has ACLs enabled, the box defaults to denying all traffic on all VLANs. In order to allow traffic through the CSS, you must configure an ACL for each VLAN to permit the traffic through the box that you desire. An explicit deny all clause exists at the end of every ACL. VLANs that do not have an ACL applied do not allow any traffic through until you configure an ACL that allows traffic. An example is shown here.

acl 10
clause 10 permit any any destination any
apply circuit-(VLAN4)
