Installing physical hardware to provide additional network interfaces in an MX7000 chassis environment requires the installation of devices into the B fabric of the MX7000 chassis. More MX9116n IOMs are installed into slots B1 and B2 on the rear of the chassis. Extra network mezzanine cards are installed into the B connector of each of MX740c compute sleds to interface with the B fabric IOMs.
Installing dedicated hardware provides better throughput, lower latency, and simplified monitoring of network performance and metrics.
