The IRF fabric splits.
•
Independent IRF fabrics merge.
NOTE:
Master election does not occur when split IRF fabrics merge. For information about the master
device of the merged IRF fabric, see "
Master election selects a master in descending order:
1.
Current master, even if a new member has higher priority.
When an IRF fabric is being formed, all members consider themselves as the master. This rule
is skipped.
2.
Member with higher priority.
3.
Member with the longest system uptime.
Two members are considered to start up at the same time if the difference between their startup
times is equal to or less than 10 minutes. For these members, the next tiebreaker applies.
4.
Member with the lowest CPU MAC address.
For the setup of a new IRF fabric, the subordinate devices must reboot to complete the setup after
the master election.
For an IRF merge, devices must reboot if they are in the IRF fabric that fails the master election.
Interface naming conventions
In standalone mode:
A physical interface is numbered in the
slot-number/subslot-number/interface-index
format.
For example, set the link type of GigabitEthernet 1/0/1 to trunk, as follows:
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] port link-type trunk
In IRF mode:
A physical interface is numbered in the
chassis-number/slot-number/subslot-number/interface-index
format. The
chassis-number
argument represents the IRF member ID.
For example, GigabitEthernet 1/2/0/1 represents the first port in slot 2 on member device 1. Set its
link type to trunk, as follows:
<Sysname> system-view
[Sysname] interface gigabitethernet 1/2/0/1
[Sysname-GigabitEthernet1/2/0/1] port link-type trunk
File system naming conventions
In standalone mode, you can use the storage device name to access the file system of the active
MPU. To access the file system of the standby MPU, use the name in the
slotslot-number#storage-device-name
format.
On a multichassis IRF fabric, you can use the storage device name to access the file system of the
global active MPU. To access the file system of a global standby MPU, use the name in the
chassismember-ID#slotslot-number#storage-device-name
format.
