Software Requirements; Irf Physical Interface Requirements - HP FlexFabric 5700 series Configuration Manual

Software requirements

All IRF member devices must run the same software image version. Make sure the software auto-update
feature is enabled on all member devices.

IRF physical interface requirements

Use 10-GE, SFP+, or QSFP+ ports for IRF links.
Selecting transceiver modules and cables
When you select transceiver modules and cables, follow these restrictions and guidelines:
Use Category 6A (or above) twisted-pair cables to connect 10-GE ports in a short distance.
•
Use SFP+/QSFP+ DAC cables to connect SFP+/QSFP+ ports in a short distance.
•
• Use SFP+/QSFP+ transceiver modules and fibers to connect SFP+/QSFP+ ports in a long distance.
The transceiver modules at the two ends of an IRF link must be the same type.
•
For more information about the SFP+/QSFP+ transceiver modules, see HP Comware-Based Devices
Transceiver Modules User Guide.
NOTE:
The SFP+/QSFP+ modules and SFP+/QSFP+ DAC cables available for the switch are subject to change
over time. For the most up-to-date list of SFP+/QSFP+ modules and DAC cables, contact HP technical
support or marketing staff.
10-GE port restrictions for the HP FlexFabric 5700-32XGT-8XG-2QSFP+ Switch and HP FlexFabric
5700-32XGT-8XG-2QSFP+ TAA-compliant Switch
When you use the 10-GE ports on the HP FlexFabric 5700-32XGT-8XG-2QSFP+ Switch (JG898A) and
HP FlexFabric 5700-32XGT-8XG-2QSFP+ TAA-compliant Switch (JG899A) as IRF physical interfaces,
follow these restrictions and guidelines:
The 10-GE ports are grouped by port number in order, starting from 1. Each group contains four
•
ports. If you use one port in a group for IRF links, you must also use all the other ports in the group
for IRF links. However, you can bind the ports to different IRF ports.
Before you bind a 10-GE port to an IRF port or remove it from the IRF port, you must shut down all
•
the 10-GE ports in the same group.
Bring up the ports after you complete the operation.
•
QSFP+ port restrictions for the HP FlexFabric 5700 switch
You can use a QSFP+ port as an IRF physical interface, or use the using tengige command to split a
QSFP+ port into four 10-GE breakout interfaces.
When you use the breakout interfaces of a 40-GE port for IRF links, follow these restrictions and
guidelines:
You must use all or none of the four 10-GE breakout interfaces as IRF physical interfaces. The four
•
breakout interfaces can be bound to different IRF ports.
Before you bind one 10-GE breakout interface to an IRF port or remove it from the IRF port, you must
•
shut down all the other 10-GE breakout interfaces. If any of the breakout interfaces are in up state,
the bind or remove action will fail.
