Fix Recommendation

This requirement is not applicable for the DODIN Backbone.

Configure ACLs based on port, source IP address, and destination IP address to permit only authorized management traffic through the OOBM interfaces used for forwarding management data.

Step 1: Configure named ACL with appropriate filter rules.

OS10(config)# ip access-list MGMT_TRAFFIC_TO_NOC
OS10(config-ipv4-acl)# permit tcp 10.10.0.0/16 10.10.0.0/16 eq 22
OS10(config-ipv4-acl)# permit udp 10.10.0.0/16 10.10.0.0/16 range 161 162
OS10(config-ipv4-acl)# permit udp 10.10.0.0/16 10.10.0.0/16 range 1812 1813
OS10(config-ipv4-acl)# permit tcp 10.10.0.0/16 10.10.0.0/16 range 1812 1813
OS10(config-ipv4-acl)# permit udp 10.10.0.0/16 10.10.0.0/16 eq 123
OS10(config-ipv4-acl)# permit udp 10.10.0.0/16 10.10.0.0/16 eq 514
OS10(config-ipv4-acl)# permit tcp 10.10.0.0/16 10.10.0.0/16 eq 6514
OS10(config-ipv4-acl)# deny ip any any log

Step 2: Apply the ACLs on the appropriate external and internal interfaces.

OS10(config-ipv4-acl)# interface ethernet1/1/1
OS10(conf-if-eth1/1/4)# ip access-group MGMT_TRAFFIC_TO_NOC out

Check Contents

This requirement is not applicable for the DODIN Backbone.

Review the network topology diagram to determine connectivity between the managed network and the NOC.

Review the OOBM gateway router configuration to validate the path that the management traffic traverses.

Verify that only management traffic is forwarded through the OOBM interface.

If traffic other than authorized management traffic is permitted through the OOBM interface, this is a finding.
