Configuring connectors and connector ports

Some assemblies have support for QSFP28 or QSFP-DD transceiver modules. These modules have different variants, some of which provide multiple physical ports out of a single module (breakout modules). There is a QSFP28 breakout module that supports ten physical 10 Gb Ethernet ports. On assemblies that support these breakout variants, the front panel cages are modeled as connectors instead of as direct ports. The connector must be configured for the type of breakout module that is to be inserted and then the appropriate ports are created and can be configured.

The connector reference is in the format slot/mda/connector (for example, 1/1/c3) and the ports owned by the connector use the format slot/mda/connector/port. For example, in a 7750 SR-1 with the 6-port QSFP28 mda-e-xp installed in the first MDA slot, initially there are no ports available, only six connectors:

After configuring a module with four 10 Gb breakout ports in connector position 1/1/c1 and a module with one 100 Gb breakout port in connector position 1/1/c2, the physical ports are created:

A:bkvm18# configure port 1/1/c1 connector breakout c4-10g
A:bkvm18# configure port 1/1/c2 connector breakout c1-100g

These physical ports can now be used as Ethernet port references in other commands.
