Figure 4-3 IRF fabric in ring topology
Identifying physical IRF ports on the member switches
Identify the physical IRF ports on the member switches according to your topology and connection
scheme.
Table 4-1 shows the physical ports that can be used for IRF connection and the port use restrictions.

•
24 × SFP+ ports on the front panel
•
2 × QSFP+ ports on the front panel
•
The following ports provided on the
expansion cards:
{
5G/2.5G/1000BASE-T
autosensing Ethernet ports
{
10G/5G/2.5G/1000BASE-T
autosensing Ethernet ports

•
Physical ports on interface cards
and the front panel can be bound to
the same IRF port.
•
All physical ports to be bound to an
IRF port must have the same data
rate.
•
To connect a
10G/5G/2.5G/1000BASE-T
autosensing Ethernet port and a
5G/2.5G/1000BASE-T
autosensing Ethernet port for an
IRF connection, the
10G/5G/2.5G/1000BASE-T
autosensing Ethernet port must
operate at 5 Gbps.
•
A QSFP+ port that is split into four
virtual SFP+ ports cannot be used
as a physical IRF port.
•
A QSFP28 port that is split into four
virtual SFP28 ports cannot be used
as a physical IRF port.
