IRF Stack HPE 1950 JG961A

[yfourar]

Hello,

I have 2 switchs HPE 1950 JG961A, I have tried several times to interconnect them with 10Gb cable CAT 7 & build an IRF stack but I couldn't, it detects nothing. so can someone please tell me where the problem is ?  

Thanks,

Yfourar

Hello @yfourar ,

Can you share IRF-Configuration from current configuration?

It would be like on SW1:

irf-port 1/1

SW1:
irf-port 1/1
port group interface Ten-GigabitEthernet 1/0/51
port group interface Ten-GigabitEthernet 1/0/52

SW2:
irf-port 2/2
port group interface Ten-GigabitEthernet 2/0/51
port group interface Ten-GigabitEthernet 2/0/52

Also, have run below command after following the IRF steps in both devices:

[HPE]  irf-port-configuration active 

 Also 'save f' the config before run above command.

Hello,

actualy I wanna interconnect the 2 switchs with only one cable, cause I need the other ports to interconnect them with 2 other switchs 1950 JG963A, I did the same configuration

- Port IRF 1/1 (TenGB 1/0/51) -----------> -Port 2/1 IRF (TenGB 2/0/51)

-Port 2/2 IRF (TenGB 2/0/52)-----------> Port 3/2 IRF (TenGB 3/0/52)

-Port 3/2 IRF (TenGB 3/0/51)-----------> Port 4/1 IRF (TenGB 4/0/51)

-Port 4/2 IRF (TenGB 4/0/52)-----------> Port 1/2 IRF (TenGB 1/0/52)

REGARDS.

Hello yfourar,

Please check the following document from page 95 for an example for the GUI (on page 24 is an explanation of the IRF and its features):

or the following video for the CLI:

Hope this helps!

Hello @yfourar,

Can you configure like below:

Port IRF 1/1 (TenGB 1/0/51) -----------> -Port 2/2 IRF (TenGB 2/0/51)

-Port 2/1 IRF (TenGB 2/0/52)-----------> Port 3/2 IRF (TenGB 3/0/52)

-Port 3/1 IRF (TenGB 3/0/51)-----------> Port 4/2 IRF (TenGB 4/0/51)

-Port 4/1 IRF (TenGB 4/0/52)-----------> Port 1/2 IRF (TenGB 1/0/52)

Thanks!

@akg7 @-Alex- 

Is it normal to use RJ45 CAT7 to interconnect the stack ? 

[akg7]

Hello @yfourar ,

No, I believe it won't be supported.

Helloyfourar,

To connect the 10GBase-T Ethernet ports in a short distance, you can use Category 6A (or above) twisted-pair cables

As mentioned in the following document on page 39:

https://support.hpe.com/hpesc/public/docDisplay?docId=c04657807 

1/10GBase-T autosensing Ethernet port

To avoid packet loss caused by interferences, layer cables as follows:
• Use category-6A or above cables and connectors.
• Do not bundle cables in their first 20 m (65.62 ft).
• Separate power cords and twisted pair cables at and around the distribution frame.
• For ports adjacent to one another on the device, the peer ports on the distribution frame are not
adjacent, for example:
{ If the device connects to one distribution frame, connect port 1 on the device to port 1 on the
distribution frame and port 2 on the device to port 3 on the distribution frame.
{ If the device connects to two distribution frames, connect port 1 on the device to port 1 on
distribution frame 1 and port 2 on the device to port 1 on distribution frame 2.
• Keep the device and twisted pair cables away from interference sources, such as a two-way
radio or a high-power variable-frequency drive.

Hope this helps!
