Overview

Daughter card objects

The NFM-P navigation tree displays daughter cards, or MDAs, as child objects of card objects.

An NFM-P license has a specific equipment management capacity. MDAs fall into two licensing categories: premium and standard. Premium MDAs consume more license capacity than standard MDAs. In general, non-high-performance MDA cards are considered standard. All IMM, HSMDA, XMDA, and XP MDA cards are premium.

Each IMM card is associated with a platform, and counts towards the licensed IMMs for that platform regardless of where it is installed. For example, a 7750 SR IMM installed on a 7450 ESS is counted as a premium 7750 SR MDA for the purposes of licensing. Enabling or disabling mixed mode does not change the associated platform type of a card.

FP4 cards on 7x50, Release 16.0 R1 and later, support license levels under card and MDA. The Licensing Details parameters appear on the Card Slot and Daughter Card Slot forms. You can set the Licensed Assigned Level that a card or daughter card slot can accept.

DCO daughter cards

CFP2-DCO daughter cards support DWDM channels, coherent optics, and optical transport channel unit (OTU). The 400 Gig QSFP-DD daughter cards and x2-1000g-wdm XMA support DWDM and coherent optics only. And other daughter cards support DWDM only. See the hardware documentation for more information about daughter card and XMA optical support.

On the NFM-P, DWDM channel and coherent optics are supported under connector ports and OTU is supported under breakout ports. See To configure connector ports and breakout ports for more information about enabling coherent optics.

IMM daughter cards

The IMM card integrates IOM 3 and high bandwidth MDA functionality on a single card that fits into existing IOM slots. When you configure the IMM the integrated MDAs are automatically configured. The NFM-P equipment tree displays the IMM with two daughter cards, each having half of the total number of ports supported by the IMM.

Each daughter card object contains a number of ports that are specific to the type of service required. The port objects are created automatically under the daughter card but they must be configured based on the function served by the port; for example, as an access interface for a VPRN service.

You can associate policies to daughter cards. Network buffer policies are used to create and edit QoS buffer pool resources on egress network ports, channels, and ingress ports. Ingress and egress network ports and channels have a dedicated buffer pool for egress queuing. The ingress and egress network traffic is handled by a buffer pool at the ingress and a buffer pool at the egress.

You can also configure multicast path management on an IMM daughter card. See Chapter 52, Multicast policies for more information.

MDA modes for the 7705 SAR

The NFM-P allows you to configure the MDA mode of some MDA types on the 7705 SAR. The MDA mode on a channelized ASAP determines the capabilities that are available to the MDA. The MDA mode on an XMDA determines the number of ports that are available to the MDA. See the MDA Mode parameter description for more information.
