IRF fabric in ring topology
Identifying physical IRF ports on the member switches
Identify the QSFP+ ports to be used for IRF connections on the member switches according to your
topology and connection scheme.
All QSFP+ ports on the HP FlexFabric 5930 switch can be used for IRF connections.
Planning the cabling scheme
For the HP FlexFabric 5930 switches, use QSFP+ cables, or QSFP+ transceiver modules and fibers to
connect the IRF member switches. If the IRF member switches are far away from one another, choose the
QSFP+ transceiver modules with optical fibers. If the IRF member switches are all in one equipment room,
choose QSFP+ cables. For more information about available QSFP+ cables and transceiver modules,
see "
QSFP+ port
."
The following subsections describe several HP recommended IRF connection schemes, and all these
schemes use a ring topology.
Connecting the IRF member switches in one rack
Use short-haul and long-haul QSFP+ cables to connect the IRF member switches (four switches in this
example) in a rack as shown in
Figure 35
. The switches in the ring topology (see
Figure 36
) are in the
same order as connected in the rack.
