Introduction to IRF
Overview
Intelligent Resilient Framework (IRF) is a software virtualization technology developed by 3Com. Its
core idea is to interconnect multiple devices through physical IRF ports and perform necessary
configurations, and then these devices are virtualized into a virtual device. This virtualization
technology realizes the cooperation of multiple devices, unified management, and non-stop
maintenance.
Hereinafter, the virtual device is called IRF.
z
At present, the S7900E Series Ethernet Switches support an IRF of two members, that is, you can
use two S7900E series switches to form an IRF: one operates as the master and the other
operates as the slave.
z
At present, the S7903E, S7906E, S7910E and S7906E-V support IRF.
Advantages
IRF has the following advantages:
z
Streamlined management
After an IRF is formed, you can log in to the IRF system by connecting to a port of any IRF member and
perform unified management to all member devices.
z
High reliability
