IRF physical ports depends on
your software release. For the actual procedure, see the
H3C S7500E Series Ethernet Switches IRF
Configuration Guide
for the software release you are using.
Planning IRF virtual device setup
Preparing for IRF virtual device setup
Before you set up an IRF virtual device, complete the following tasks:
1. Select IRF-capable S7500E switches for your network. IRF-capable S7500E switches include the
S7503E, S7506E, S7510E, and S7506E-V.
NOTE:
• You can establish an IRF virtual device that comprises different S7500E switch models.
• The member switches in an IRF must use the same version of boot file.
2. Select cards that can provide 10-GE optical ports for the member switches. Available cards
include the LSQ1SRP2XB (LSQM1SRP2XB) SRPU, and the SC–, SD–, and EB–type LPUs.
NOTE:
• The S7500E series require 10-GE optical ports for IRF connection.
• For more information about the cards, see Appendix B “Pluggable module ordering guide.”
3. Select transceiver modules (XFP or SFP+) and fibers for long-haul IRF connection, or select SFP+
cables for short-haul IRF connection. For more information about transceiver modules and SFP+
cables, see Appendix B “Pluggable module ordering guide.”
4. Plan the installation site.
Planning the IRF network
Plan the IRF network and identify the role, member ID, physical IRF ports of each member switch.
For IRF configuration and management, see the H3C S7500E Series Ethernet Switches IRF Configuration
Guide.
Identifying the master switch
Determine which switch you want to use as the master for managing all member switches in the IRF virtual
device.
An IRF virtual device has only one master. You configure and manage all member switches in the IRF
virtual device at the command line interface of the master.
Planning member IDs
An IRF virtual device uses member IDs to uniquely identify and manage its members.
Assign each IRF member switch a unique member ID before connecting them to form an IRF virtual
device.
