HP 6125XLG Virtual Chassis (IRF)

During IRF configuration on  HP 6125XLG switches(firmware CMW710-R2422P01), I have faced a lot of problems like:

  • System errors - sorry don't have output of the error message. I hope I can give them in the nearest future.
  • After configuring the devices the slave switch rebooted but not in Virtual Chassis membership

The first issue was caused by SFP+ modules, yea it can be tricky when you don't use internal interconnect ports. Unplugging all SFP+ resolved the problem, but after restart applying the configuration switch rebooted in standalone mode. The resolve the last problem the ports on the Master switch has to be disabled, and enabled after all configs are applied and save on slave.

  1. Master switch configuration
mkdir configs
interface range Ten-GigabitEthernet 1/0/17 to Ten-GigabitEthernet1/0/20
 shutdown
quit

sysname <CLUSTER_NAME>

irf member 1 priority 32
irf-port 1/1
 port group interface Ten-GigabitEthernet1/0/17
 port group interface Ten-GigabitEthernet1/0/18
 port group interface Ten-GigabitEthernet1/0/19
 port group interface Ten-GigabitEthernet1/0/20
quit
irf-port-configuration active

save
  1. Slave switch configuration
mkdir configs
system-view

irf member 1 renumber 2
quit 
save
reboot
After reboot:
system-view
irf member 2 priority 16

interface range Ten-GigabitEthernet 2/0/17 to Ten-GigabitEthernet2/0/20
 shutdown
quit

sysname <CLUSTER_NAME>

irf-port 2/2
 port group interface Ten-GigabitEthernet2/0/17
 port group interface Ten-GigabitEthernet2/0/18
 port group interface Ten-GigabitEthernet2/0/19
 port group interface Ten-GigabitEthernet2/0/20
quit

irf-port-configuration active

interface range Ten-GigabitEthernet 2/0/17 to Ten-GigabitEthernet2/0/20
 undo shutdown
quit

save
  1. Go back to SWITCH-1 (master) and enable the ports
system-view

interface range Ten-GigabitEthernet 1/0/17 to Ten-GigabitEthernet1/0/20
 undo shutdown
quit

save

Right after you enable the ports of the Master device, slave will be rebooted and merge into Virtual Chassis.
