Identifying Physical Irf Ports On The Member Switches; Planning The Cabling Scheme - HP HPE FlexFabric 5944 Series Installation Manual

Figure4-3 IRF fabric in ring topology
You can set up 100/40-GE IRF physical connections by connecting only QSFP28 ports between
HPE 5944 48XGT 6QS28 switches.
You can bind several ports to an IRF port for increased bandwidth and availability.

Identifying physical IRF ports on the member switches

Identify the QSFP28 ports for IRF connections on the member switches according to your topology
and connection scheme.
All the QSFP28 ports on the switch can be used for IRF connections.

Planning the cabling scheme

You can use only QSFP28 transceiver modules and optical fibers, QSFP28 fiber cables, QSFP28
copper cables, QSFP transceiver modules and optical fibers, QSFP fiber cables, or QSFP copper
cables to connect the switches for IRF connections.
If the IRF member switches are far away from one another, choose QSFP+/QSFP28 transceiver
modules and optical fibers. If the IRF member switches are all in one equipment room, use
QSFP/QSFP28 copper or fiber cables. For more information about transceiver modules and cables
available for the switch, see
The following subsections describe several IRF connection schemes by using QSFP28 transceiver
modules and optical fibers, QSFP28 copper cables, and QSFP28 fiber cables. All these schemes
use a ring topology.
Connecting the IRF member switches in one rack
Figure4-4 shows an example for connecting four IRF member switches in a rack. The switches in the
ring topology (see Figure4-5) are in the same order as connected in the rack.
