HP A5120 Switch IRF configurations

Hi All,

 

I am trying to configure IRF between two HP A5120 SWs, but it's always failing due to link timeout.

 

I used the HP A5120 EI Switch Series IRF Configuration Guide as reference when installing.

 

I use two 10G interfaces for the IRF configs.

 

so any help will be much appreciated.

Re: HP A5120 Switch IRF configurations

 

Here are the config i used:

 

Device A:

 

system-view
sysname STM-TMM-SW01
irf domain 10

 

Device B:

 

system-view
sysname STM-TMM-SW02
irf domain 10

irf member 1 renumber 2

 

Then I powered off the two sws and then connected the two fibre cables and powered the SWs on again and run the following command:

 

Device A:

 

system-view
interface Ten-GigabitEthernet 1/2/1
shutdown
quit
interface Ten-GigabitEthernet 1/2/2
shutdown
quit

irf-port 1/1
port group interface Ten-GigabitEthernet 1/2/1 mode normal
port group interface Ten-GigabitEthernet 1/2/2 mode normal
quit

interface Ten-GigabitEthernet 1/2/1
undo shutdown
interface Ten-GigabitEthernet 1/2/2
undo shutdown

 

Device B:

 

system-view
interface Ten-GigabitEthernet 2/2/1
shutdown
quit
interface Ten-GigabitEthernet 2/2/2
shutdown
quit

irf-port 2/1
port group interface Ten-GigabitEthernet 2/2/1 mode normal
port group interface Ten-GigabitEthernet 2/2/2 mode normal
quit

interface Ten-GigabitEthernet 2/2/1
undo shutdown

interface Ten-GigabitEthernet 2/2/2
undo shutdown

 

 

Then

DeviceA:

irf-port-configuration active

 

DeviceB:

irf-port-configuration active

Re: HP A5120 Switch IRF configurations

IRF should be connected between logical IRF port 1 to logical IRF port 2, now you're using only 1 (1/1 and 2/1). on device B, use irf-port 2/2 instead.

Re: HP A5120 Switch IRF configurations

Thanks a lot for your feedback. This change has actually fixed the problem.

 

last thing, from dis irf conf command, why there is disabled stat for ports? any idea why?

See the IRF command reference. If you have not bound any physical links to an IRF port, its link state is Disabled.

Re: HP A5120 Switch IRF configurations

There are two logical IRF ports on each device so that you can configure 2+ of them in a ring for redundancy. When you have only two devices connected to each other you can use either one 10G port to each logical IRF port and configure the two devices in a small ring between each other, or use both 10G interfaces in the same logical IRF which basically makes the IRF connection point to point.

Re: HP A5120 Switch IRF configurations

Hi Fredrik,

 

Could i use IRF-Port 1 in Device A to connect to IRF-Port 1 in Device B? Please advise.
