Vulnerability discussion

The out-of-band management access switch will connect to the management interface of the managed network elements. The management interface can be a true out-of-band management interface or a standard interface functioning as the management interface. In either case, the management interface of the managed network element will directly connect to the out-of-band management network.An out-of-band management interface does not forward transit traffic, thereby, providing complete separation of production and management traffic. Since all management traffic is immediately forwarded into the management network, it is not exposed to possible tampering. The separation also ensures that congestion or failures in the managed network do not affect the management of the device. If the device does not have an out-of-band management port, the interface functioning as the management interface must be configured so that management traffic, both data plane and control plane, does not leak into the managed network and that production traffic does not leak into the management network.

Check content

Review the configuration to verify the OOBM interface belongs to a different OSPF instance (process) than the production network. If the management interface does not belong to a different OSPF instance, this is a finding. Note: By default an OOBM interface is passive to a routing protocol.

Fix text

If OSPF is used for the management network, configure the OOBM interface to belong to a different OSPF instance than the production network.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
