Figure 4 IRF merge Member priority Member priority determines the possibility of a member device to be elected the master. A member with higher priority is more likely to be elected the master. The default member priority is 1. You can change the member priority of a member device to affect the master election result. Interface naming conventions An interface is named in the format of chassis-id/slot-number/port-index, where: • chassis-id-IRF member ID of the switch. This argument defaults to 1. • slot-number-Represents the slot number of the interface card. This argument always takes 0 on HP 6125 switches. • port-index-Port index depends on the number of ports available on the switch. To identify the index of a port, look at its port index mark on the chassis. For one example, on the standalone switch Sysname, GigabitEthernet 1/0/1 represents the first fixed port on the front panel. Set its link type to trunk, as follows: system-view [Sysname] interface gigabitethernet 1/0/1 [Sysname-GigabitEthernet1/0/1] port link-type trunk For another example, on the IRF fabric Master, GigabitEthernet 3/0/1 represents the first fixed port on the front panel of member switch 3. Set its link type to trunk, as follows: system-view 4

IRF merge
IRF merge occurs when two split IRF fabrics re-unite or when you configure and connect two independent
IRF fabrics to be one IRF fabric, as shown in
Figure 4

Member priority
Member priority determines the possibility of a member device to be elected the master. A member with
higher priority is more likely to be elected the master.
The default member priority is 1. You can change the member priority of a member device to affect the
master election result.
Interface naming conventions
An interface is named in the format of
chassis-id
/
slot-number
/
port-index
, where:
•
chassis-id
—IRF member ID of the switch. This argument defaults to 1.
•
slot-number
—Represents the slot number of the interface card. This argument always takes 0 on HP
6125 switches.
•
port-index
—Port index depends on the number of ports available on the switch. To identify the
index of a port, look at its port index mark on the chassis.
For one example, on the standalone switch Sysname, GigabitEthernet 1/0/1 represents the first fixed
port on the front panel. Set its link type to trunk, as follows:
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] port link-type trunk
For another example, on the IRF fabric Master, GigabitEthernet 3/0/1 represents the first fixed port on
the front panel of member switch 3. Set its link type to trunk, as follows:
<Master> system-view
