| Description |

| The OOBM access switch will connect to the management interface of the managed network elements. The management interface can be a true OOBM interface or a standard interface functioning as the management interface. In either case, the management interface of the managed network element will be directly connected to the OOBM network. An OOBM 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. |

| Review the managed switch configuration and verify that an address has been configured for management VLAN from space belonging to the OOBM network that has been assigned to that site. interface VLAN10 ip address 10.1.1.10 255.255.255.0 description Management VLAN Note: The IP address of the switch can be accessed only by nodes connected to ports that belong to the management VLAN. A default gateway address as shown below must be configured using the address of the OOBM gateway router interface connecting to the OOBM access switch. This will ensure that all management traffic is forwarded toward the NOC using the switchport attached to the OOBM access switch. ip default-gateway 10.1.1.1 |
