Description
The Out-of-Band Management (OOBM) network is an IP network used exclusively for the transport of OAM&P data from the network being managed to the OSS components located at the NOC. Its design provides connectivity to each managed network element enabling network management traffic to flow between the managed NEs and the NOC. This allows the use of paths separate from those used by the network being managed. Traffic from the managed network to the management network and vice-versa must be secured via IPSec encapsulation.

Check Text ( C-19015r1_chk )
Verify that all traffic from the managed network to the management network and vice-versa is secured via IPSec encapsulation.

Fix Text (F-17652r1_fix)
Where IPSec technology is deployed to connect the OOBM gateway routers or firewall, traffic entering the tunnels is restricted to only the authorized management packets based on destination and source IP address from the address block used for the management network.
