Management Overview


The BTI7800 supports both inband management (releases 2.1.1 and higher) and out-of-band management. The inband management network runs over the optical network infrastructure while the out-of-band management network connects to the BTI7800 over a separate management Ethernet connection. A typical deployment uses both methods where inband management is used throughout except for those network elements (NEs) not part of the optical network.

This is shown in the following figure where the NEs that are part of the optical network infrastructure are managed inband while the NEs not part of the optical network infrastructure are managed over out-of-band management Ethernet connections. The NE on the far right acts as a gateway, routing management traffic between its out-of-band management Ethernet interface and the inband management network.

Management functionality for the BTI7800 resides within the Chassis Management Module (CMM). Each network element contains up to two CMMs (for redundancy), with each CMM connecting separately to the management Ethernet network if out-of-band management is required. If one connection goes down, the network element is still reachable through the other link. In the inband management network where management traffic is sent over optical links, redundancy is provided through proper optical network design.

You can get access to the NE’s management software interface by connecting to a management IP address that is shared between the two CMMs. The IP address is the same regardless of whether the network element is being managed out-of-band or inband. Although both CMMs share this same IP address, only the currently active CMM owns (and responds to) the shared IP address. Additionally, each CMM can be assigned its own dedicated individual IP address. Use of this individual IP address is for advanced troubleshooting and is beyond the scope of this document.

You have the choice of connecting to the following management software interfaces on the CMM:

  • CLI on the active CMM through the shared management IP address

  • NETCONF on the active CMM through the shared management IP address

  • SNMP on the active CMM through the shared management IP address

  • Management OS shell:

    • on the active CMM, through the shared management IP address or through the active CMM's individual IP address

    • on the standby CMM, through the standby CMM's individual IP address

    Working with the management OS shell is for advanced troubleshooting only and is beyond the scope of this document.

For the port numbers to use to connect to these management software interfaces, see BTI7800 Port Usage.


The following constraints apply to the management network:

  • On any given network element, the shared IP address, the individual CMM IP addresses, and the default gateway must all reside on the same subnet.

  • Each BTI7800 network element should be managed by at most two PSM servers (for performance reasons).

  • The management network must support an MTU size of 1500 bytes.
