Connecting Physical Irf Ports - H3C S5120-EI Series Configuration Manual

A member priority change affects the election result at the next master election, but does not cause
immediate master re-election.
To specify a priority for the switch:
Step
1. Enter system view.
2. Specify a priority for the
switch.

Connecting physical IRF ports

When you connect two neighboring IRF members, connect the physical ports of IRF-port 1 on one
member to the physical ports of IRF-port 2 on the other, as shown in
IMPORTANT:
No intermediate devices are allowed between neighboring members.
Figure 8 Connecting IRF physical ports
Connect the switches into a daisy chain topology or a ring topology, which is more reliable (see
9). In ring topology, the failure of one IRF link does not cause the IRF fabric to split as in daisy chain
topology. Rather, the IRF fabric changes to a daisy chain topology without interrupting network services.
