Identifying physical IRF ports on the member switches

Identify the physical IRF ports on the member switches according to your topology and connection
scheme.
When using a combo interface for IRF connection, configure the fiber or copper port of the combo
interface as active. For how to configure the combo interface state, see the HP 3100-48 v2 Switch Layer
2—LAN Switching Configuration Guide.

Planning the cabling scheme

Use GE Ethernet twisted pairs, SFP IRF modules or SFP transceiver modules, and fibers to connect the IRF
member switches. If the IRF member switches are far away from one another, choose GE Ethernet twisted
pairs or the SFP transceiver modules with optical fibers. If the IRF member switches are all in one rack,
choose SFP IRF modules.
Table 1 1 lists the SFP transceiver modules and SFP IRF modules available for IRF connections.
The following subsections describe several IRF connection schemes and use SFP IRF modules or SFP
transceiver modules with optical cables for example. All these schemes use a ring topology.
Connecting the IRF member switches in one rack
NOTE:
This example uses nine switches.
You can connect the IRF member switches in one rack (see
topology.
