Identifying Physical Irf Ports On The Member Switches; Planning The Cabling Scheme - H3C S5560X-30C-EI Installation Manual

Identifying physical IRF ports on the member switches

Identify the physical IRF ports on the member switches according to your topology and connection
scheme.
Table4-1 shows the physical ports that can be used for IRF connection and the port use restrictions.

Planning the cabling scheme

The cables available for connecting two peer IRF physical ports vary by port type:
•
1/10GBASE-T, 5G/2.5G/1000BASE-T, and 10G/5G/2.5G/1000BASE-T autosensing
Ethernet ports—For the available cables, see ports in Hardware Information and
Specifications.
•
SFP+ ports—SFP+ transceiver modules and optical fibers or SFP+ cables. For the available
transceiver modules and cables, see ports in Hardware Information and Specifications.
•
SFP28 ports—SFP28 transceiver modules and optical fibers or SFP28 cables. For the
available transceiver modules and cables, see ports in Hardware Information and
Specifications.
•
QSFP+ ports—QSFP+ transceiver modules and optical fibers or QSFP+ cables. For the
available transceiver modules and cables, see ports in Hardware Information and
Specifications.
For a short-distance IRF connection in an equipment room, use a twisted-pair cable, SFP+ cable,
SFP28 cable, or QSFP+ cable.
For a long-distance IRF connection, use SFP+/SFP28/QSFP+ transceiver modules and optical
fibers.
The following subsections describe several H3C recommended IRF connection schemes. All these
schemes use a ring topology.
Candidate physical IRF ports
•
Four SFP+ ports on the front panel
•
Two QSFP+ ports on the rear panel
•
Four fixed SFP+ ports on the front
panel
•
Ports on the interface cards on the
rear panel:

Requirements
•
All physical ports to be bound to an
IRF port must have the same data
rate.
•
Physical ports on interface cards
and the front panel can be bound to
the same IRF port.
•
If a QSFP+ port is split into four
virtual SFP+ ports, the QSFP+ port
cannot be used as a physical IRF
port.
