Fix Recommendation

If the management interface is a routed interface, configure it with both an ingress and egress ACL. The ingress ACL should block any transit traffic, while the egress ACL should block any traffic that was not originated by the managed network device.

Check Contents

1. Verify the managed interface has an inbound and outbound ACL or filter.

2. Verify the ingress ACL blocks all transit traffic (any traffic not destined to the router itself). In addition, traffic accessing the managed elements should be originated at the NOC.

3. Verify the egress ACL blocks any traffic not originated by the managed element.

If the management interface does not have an ingress and egress filter configured and applied, this is a finding.
