Identifying Physical Irf Ports On The Member Switches; Planning The Cabling Scheme - H3C S5170-EI Series 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

Use the following cables to connect the IRF physical ports on the switch:
•
10/100/1000BASE-T autosensing Ethernet port—Category 5 or above twisted-pair cable.
•
100BASE-TX/1000BASE-T/2.5GBASE-T autosensing Ethernet port—Category 5e or above
twisted-pair cable.
•
SFP port—GE SFP fiber transceiver module and optical fiber, GE SFP copper transceiver
module and twisted pair cable or GE SFP cable. For the available transceiver models and
cables, see ports in S5170-EI & S5570S-EI Switch Series Hardware Information and
Specifications.
•
SFP+ port—SFP+ fiber transceiver module and optical fiber or SFP+ cable. For the available
transceiver models and cables, see ports in S5170-EI & S5570S-EI Switch Series Hardware
Information and Specifications.
For a short-distance IRF connection in an equipment room, use a twisted pair/SFP+/SFP cable.
For a long-distance IRF connection, use transceiver modules and optical fibers.

Use restrictions
•
Physical ports on interface modules
and the front panel can be bound to
the same IRF logical interface.
•
All physical ports to be bound to an
IRF logical interface must have the
same data rate.
•
A 10/100/1000BASE-T autosensing
Ethernet port or SFP port can be
used as an IRF physical port only
when it operates at 1 Gbps.
•
A
100BASE-TX/1000BASE-T/2.5GBA
SE-T autosensing Ethernet port can
be used as an IRF physical port only
when it operates at 2.5 Gbps.
•
An SFP+ port can be used as an IRF
physical port only when it operates at
10 Gbps.
•
For a switch that has six SFP+ ports,
use the four SFP+ ports with the
highest numbers as IRF ports. For a
switch that has four SFP+ ports, use
the two SFP+ ports with the highest
numbers as IRF ports. Using these
ports as IRF ports can prevent issues
such as IRF split, because IRF
protocol packets from these ports
can be forwarded in a queue with a
higher priority.
