Learn how to configure IRF on HP switches in this short, easy and real-world tutorial:
Intelligent Resilient Framework (IRF) - is an HP technology that allows you to stack multiple physical switches into one logical switch.
Master-Slave Election:
1. The switch that's the master stays the current master.
2. If the master goes down, one of the slaves becomes the master.
3. If the master switch comes back again, it will come back as a slave because the current master stays the current master.
4. If you don't have a current master, it's done on priorities.
Note: 32 being the highest to force a switch to become a master. Default priority is 1.
IRF Configuration Steps (Short and Easy)
1. Connect the switches using two ten-gigabitethernet ports and power them up. See example ports below.
int range ten-gigabitethernet1/0/51 to ten-gigabitethernet1/0/52
2. Console into Switch2 and issue the following commands to verify port and irf status
display int brief
display irf
3. Renumber Switch2 ports, save configs and reboot it
system-view
sysname Switch2
irf member 1 renumber 2
save force
reboot
Once it has rebooted, issue the following commands:
display int description !to check that the ports have been renumbered
display irf !to check that the switch has become switch2
!
irf domain 10 !default is 0
irf mac-address persistent timer !This bridge MAC address is used by Layer 2 protocols, for example, LACP, to identify the IRF fabric, and must be unique on a switched LAN for proper communication.
irf auto-update enable !The software auto-update function automatically synchronizes the urrent software images of the master in an IRF fabric to all its members.
undo irf link-delay !default config
irf member 2 priority 20
irf member 2 description Stack1-Slave
interface range Ten-GigabitEthernet2/0/51 to Ten-GigabitEthernet2/0/52
shut
!
irf-port 2/1 !logical irf port
port group interface Ten-GigabitEthernet2/0/51 !adding physical port to the irf port
irf-port 2/2 !logical irf port
port group interface Ten-GigabitEthernet2/0/52 !adding physical port to the irf port
!
interface range Ten-GigabitEthernet2/0/51 to Ten-GigabitEthernet2/0/52
undo shut
irf-port-configuration active
save force !this is important before you undo shut the physical ports on the master switch.
!
display irf !You will that it's the master because it's NOT a member of the IRF fabric yet.
!memberID will be 2.
4. Console into Switch1(Master)
system-view
sysname Switch1
irf domain 10
irf mac-address persistent timer !default config
irf auto-update enable !default config
undo irf link-delay !default config
irf member 1 priority 30
irf member 1 description Stack1-Master
quit
interface range ten-gigabit 1/0/51 to Ten-GigabitEthernet 1/0/52
shutdown
irf-port 1/1
port group int ten-gigabitethernet1/0/51
irf-port 1/2
port group int ten-gigabitethernet1/0/52
!
irf-port-configuration active
!
interface range ten-gigabit 1/0/51 to Ten-GigabitEthernet 1/0/52 ! this will cause Switch2 to reboot as it will be added to the Stack.
undo shut
5. Still on Switch1 via console connection.
Once Switch2 has rebooted, issue the following commands:
display interface brief - You will see that the ports have been combined.
display irf
display irf configuration
display irf topology
