Hello, 

for whatever reason I cant get a link between an Aruba 6200F and an Aruba 8325 over fibre.

The situation:

Both are lag and lacp active configured. I tripple-checked, if I swapped RX and TX. 

The tranceivers are on both ends J9150D and they see each other.

These are the configs:

8325:

 Status
  Temperature : 23.80C
  Voltage     : 3.30V
  Tx Bias     : 5.33mA
  Rx Power    : 0.39mW, -4.09dBm
  Tx Power    : 0.51mW, -2.92dBm

interface lag 17 multi-chassis
    no shutdown
    no routing
    vlan trunk native 1
    vlan trunk allowed all
    lacp mode active

6200F:

  ------------------------------------------------------------
  Lane  Tx Bias           Rx Power          Tx Power
        (mA)              (mW/dBm)          (mW/dBm)
  ------------------------------------------------------------
  1     6.2280            0.3112 / -5.07    0.5372 / -2.70

interface lag 1
    no shutdown
    no routing
    vlan trunk native 1
    vlan trunk allowed all
    lacp mode active

I hope you can tell me, why I cant get a link between those.

Hi, it could be for a lot of reasons. I would normally start with the physical layer. But with the 8325 I would start with the interface-group config

system interface-group 1 speed 10g

    !interface group 1 contains ports 1/1/1-1/1/12

system interface-group 2 speed 10g

    !interface group 2 contains ports 1/1/13-1/1/24

system interface-group 3 speed 10g

    !interface group 3 contains ports 1/1/25-1/1/36

Then:

• Is the fibre a blue multimode fibre?
• Is it a short enough cable?
• Do you have a second cable to test?

• What is the interface config for each of the physical interfaces?
• what output for "show interface 1/1/x tran"?
• what is the "show interface 1/1/x" on each switch?

for the distance:

the weird thing about this situation is, that the distance works fine if I use older switches (8206 and 2610) and transceivers (J4858C) (we need to exchange the old ones).

It looks something like this:

Switch ---------> Panel -----------> Switch

I hope my thoughts are clear enough.

Hi, it looks like you've done all the config checks necessary. The only thing I can add is some experience from a recent comware to CX hardware swap. I had comware edge switches connected via SR optics to a comware switch. All fine. Move the fibre to the CX8360 and the liinks would not work. In my case I actually got an occasional flash on the front of the switch, but not enough link to pass frames. Everything was equal because this was a simple hardware swap. Other SR connections on the new CX were fine. Right now I have the old comware switch acting as a media convertor between edge switch and router (ugly).

Note, the fibre length is likely on the limits. I didn't question it with this hardware swap since two generations worked fine before (procurve and comware).

Given that there are constraints on some models such as not allowing LRM, I suspect the power provided per port is lower than other hardware. So my next step if I was you would be to put a known working switch at each end and swap to a new CX one at a time. If using the same interfaces on both switches (but bring one switch to the other's rack) you get a link, you will be observing the same thing as I did.

The interface group config is the same as you posted for all three groups.

Hello, 

for whatever reason I cant get a link between an Aruba 6200F and an Aruba 8325 over fibre.

Both are lag and lacp active configured. I tripple-checked, if I swapped RX and TX. 

The tranceivers are on both ends J9150D and they see each other.

These are the configs:

interface lag 17 multi-chassis
    no shutdown
    no routing
    vlan trunk native 1
    vlan trunk allowed all
    lacp mode active

I hope you can tell me, why I cant get a link between those.

Hi,

I will try it another day to swap one by one. Did your setup work after your one by one swap?

I just dont understand why it is not working with CX Switches and why I cant get a link even though every transceiver receives a signal within operating spec.

Hope someone can explain this to me

the weird thing about this situation is, that the distance works fine if I use older switches (8206 and 2610) and transceivers (J4858C) (we need to exchange the old ones).

I hope my thoughts are clear enough.

Hi, it could be for a lot of reasons. I would normally start with the physical layer. But with the 8325 I would start with the interface-group config

system interface-group 1 speed 10g

    !interface group 1 contains ports 1/1/1-1/1/12

system interface-group 2 speed 10g

    !interface group 2 contains ports 1/1/13-1/1/24

system interface-group 3 speed 10g

    !interface group 3 contains ports 1/1/25-1/1/36

Then:

• Is the fibre a blue multimode fibre?
• Is it a short enough cable?
• Do you have a second cable to test?

• What is the interface config for each of the physical interfaces?
• what output for "show interface 1/1/x tran"?
• what is the "show interface 1/1/x" on each switch?

Hello, 

for whatever reason I cant get a link between an Aruba 6200F and an Aruba 8325 over fibre.

The situation:

Both are lag and lacp active configured. I tripple-checked, if I swapped RX and TX. 

The tranceivers are on both ends J9150D and they see each other.

These are the configs:

8325:

  Tx Bias     : 5.33mA
  Rx Power    : 0.39mW, -4.09dBm

    vlan trunk native 1
    vlan trunk allowed all
    lacp mode active

    vlan trunk native 1
    vlan trunk allowed all
    lacp mode active

I hope you can tell me, why I cant get a link between those.

Any Follow up?

Hi,

I will try it another day to swap one by one. Did your setup work after your one by one swap?

I just dont understand why it is not working with CX Switches and why I cant get a link even though every transceiver receives a signal within operating spec.

Hope someone can explain this to me

Hi, it looks like you've done all the config checks necessary. The only thing I can add is some experience from a recent comware to CX hardware swap. I had comware edge switches connected via SR optics to a comware switch. All fine. Move the fibre to the CX8360 and the liinks would not work. In my case I actually got an occasional flash on the front of the switch, but not enough link to pass frames. Everything was equal because this was a simple hardware swap. Other SR connections on the new CX were fine. Right now I have the old comware switch acting as a media convertor between edge switch and router (ugly).

Note, the fibre length is likely on the limits. I didn't question it with this hardware swap since two generations worked fine before (procurve and comware).

Given that there are constraints on some models such as not allowing LRM, I suspect the power provided per port is lower than other hardware. So my next step if I was you would be to put a known working switch at each end and swap to a new CX one at a time. If using the same interfaces on both switches (but bring one switch to the other's rack) you get a link, you will be observing the same thing as I did.

the weird thing about this situation is, that the distance works fine if I use older switches (8206 and 2610) and transceivers (J4858C) (we need to exchange the old ones).

Hi, it could be for a lot of reasons. I would normally start with the physical layer. But with the 8325 I would start with the interface-group config

system interface-group 1 speed 10g

    !interface group 1 contains ports 1/1/1-1/1/12

system interface-group 2 speed 10g

    !interface group 2 contains ports 1/1/13-1/1/24

system interface-group 3 speed 10g

    !interface group 3 contains ports 1/1/25-1/1/36

Then:

• Is the fibre a blue multimode fibre?
• Is it a short enough cable?
• Do you have a second cable to test?

• What is the interface config for each of the physical interfaces?
• what output for "show interface 1/1/x tran"?
• what is the "show interface 1/1/x" on each switch?

Hello, 

for whatever reason I cant get a link between an Aruba 6200F and an Aruba 8325 over fibre.

The situation:

Both are lag and lacp active configured. I tripple-checked, if I swapped RX and TX. 

The tranceivers are on both ends J9150D and they see each other.

These are the configs:

8325:

    vlan trunk allowed all
    lacp mode active

    vlan trunk allowed all

I hope you can tell me, why I cant get a link between those.

Hi,

no, all devices are original HPE Aruba devices. Even the Transceiver. Model is J9150D.

Since last time I haven't tried exchange them one by one. Didn't have time.

Hi,

Do you have any other transceivers installed in the switch (any third party devices attached)?

Hi,

I will try it another day to swap one by one. Did your setup work after your one by one swap?

I just dont understand why it is not working with CX Switches and why I cant get a link even though every transceiver receives a signal within operating spec.

Hope someone can explain this to me

Hi, it looks like you've done all the config checks necessary. The only thing I can add is some experience from a recent comware to CX hardware swap. I had comware edge switches connected via SR optics to a comware switch. All fine. Move the fibre to the CX8360 and the liinks would not work. In my case I actually got an occasional flash on the front of the switch, but not enough link to pass frames. Everything was equal because this was a simple hardware swap. Other SR connections on the new CX were fine. Right now I have the old comware switch acting as a media convertor between edge switch and router (ugly).

Note, the fibre length is likely on the limits. I didn't question it with this hardware swap since two generations worked fine before (procurve and comware).

Given that there are constraints on some models such as not allowing LRM, I suspect the power provided per port is lower than other hardware. So my next step if I was you would be to put a known working switch at each end and swap to a new CX one at a time. If using the same interfaces on both switches (but bring one switch to the other's rack) you get a link, you will be observing the same thing as I did.

for the distance:

the weird thing about this situation is, that the distance works fine if I use older switches (8206 and 2610) and transceivers (J4858C) (we need to exchange the old ones).

It looks something like this:

I hope my thoughts are clear enough.

Hi, it could be for a lot of reasons. I would normally start with the physical layer. But with the 8325 I would start with the interface-group config

system interface-group 1 speed 10g

    !interface group 1 contains ports 1/1/1-1/1/12

system interface-group 2 speed 10g

    !interface group 2 contains ports 1/1/13-1/1/24

system interface-group 3 speed 10g

    !interface group 3 contains ports 1/1/25-1/1/36

Then:

• Is the fibre a blue multimode fibre?
• Is it a short enough cable?
• Do you have a second cable to test?

• What is the interface config for each of the physical interfaces?
• what output for "show interface 1/1/x tran"?
• what is the "show interface 1/1/x" on each switch?

Hello, 

for whatever reason I cant get a link between an Aruba 6200F and an Aruba 8325 over fibre.

The situation:

Both are lag and lacp active configured. I tripple-checked, if I swapped RX and TX. 

The tranceivers are on both ends J9150D and they see each other.

These are the configs:

8325:

I hope you can tell me, why I cant get a link between those.

Hi,

I will try it another day to swap one by one. Did your setup work after your one by one swap?

I just dont understand why it is not working with CX Switches and why I cant get a link even though every transceiver receives a signal within operating spec.

Hope someone can explain this to me

Hi, it looks like you've done all the config checks necessary. The only thing I can add is some experience from a recent comware to CX hardware swap. I had comware edge switches connected via SR optics to a comware switch. All fine. Move the fibre to the CX8360 and the liinks would not work. In my case I actually got an occasional flash on the front of the switch, but not enough link to pass frames. Everything was equal because this was a simple hardware swap. Other SR connections on the new CX were fine. Right now I have the old comware switch acting as a media convertor between edge switch and router (ugly).

Note, the fibre length is likely on the limits. I didn't question it with this hardware swap since two generations worked fine before (procurve and comware).

Given that there are constraints on some models such as not allowing LRM, I suspect the power provided per port is lower than other hardware. So my next step if I was you would be to put a known working switch at each end and swap to a new CX one at a time. If using the same interfaces on both switches (but bring one switch to the other's rack) you get a link, you will be observing the same thing as I did.

Hi, it looks like you've done all the config checks necessary. The only thing I can add is some experience from a recent comware to CX hardware swap. I had comware edge switches connected via SR optics to a comware switch. All fine. Move the fibre to the CX8360 and the liinks would not work. In my case I actually got an occasional flash on the front of the switch, but not enough link to pass frames. Everything was equal because this was a simple hardware swap. Other SR connections on the new CX were fine. Right now I have the old comware switch acting as a media convertor between edge switch and router (ugly).

Note, the fibre length is likely on the limits. I didn't question it with this hardware swap since two generations worked fine before (procurve and comware).

Given that there are constraints on some models such as not allowing LRM, I suspect the power provided per port is lower than other hardware. So my next step if I was you would be to put a known working switch at each end and swap to a new CX one at a time. If using the same interfaces on both switches (but bring one switch to the other's rack) you get a link, you will be observing the same thing as I did.

The interface group config is the same as you posted for all three groups.

For your other questions:

Hi, it looks like you've done all the config checks necessary. The only thing I can add is some experience from a recent comware to CX hardware swap. I had comware edge switches connected via SR optics to a comware switch. All fine. Move the fibre to the CX8360 and the liinks would not work. In my case I actually got an occasional flash on the front of the switch, but not enough link to pass frames. Everything was equal because this was a simple hardware swap. Other SR connections on the new CX were fine. Right now I have the old comware switch acting as a media convertor between edge switch and router (ugly).

Note, the fibre length is likely on the limits. I didn't question it with this hardware swap since two generations worked fine before (procurve and comware).

Given that there are constraints on some models such as not allowing LRM, I suspect the power provided per port is lower than other hardware. So my next step if I was you would be to put a known working switch at each end and swap to a new CX one at a time. If using the same interfaces on both switches (but bring one switch to the other's rack) you get a link, you will be observing the same thing as I did.

The interface group config is the same as you posted for all three groups.

For your other questions:

for the distance:

the weird thing about this situation is, that the distance works fine if I use older switches (8206 and 2610) and transceivers (J4858C) (we need to exchange the old ones).

It looks something like this:

Switch ---------> Panel -----------> Switch

I hope my thoughts are clear enough.

Hi, it could be for a lot of reasons. I would normally start with the physical layer. But with the 8325 I would start with the interface-group config

system interface-group 1 speed 10g

    !interface group 1 contains ports 1/1/1-1/1/12

system interface-group 2 speed 10g

    !interface group 2 contains ports 1/1/13-1/1/24

system interface-group 3 speed 10g

    !interface group 3 contains ports 1/1/25-1/1/36

Then:

• Is the fibre a blue multimode fibre?
• Is it a short enough cable?
• Do you have a second cable to test?

• What is the interface config for each of the physical interfaces?
• what output for "show interface 1/1/x tran"?
• what is the "show interface 1/1/x" on each switch?

Hello, 

for whatever reason I cant get a link between an Aruba 6200F and an Aruba 8325 over fibre.

This question has not been asked before.

The 8325 is a VSX with multi-chassis enabled. 

We use original HPE Aruba J9150D SFP+ Transceivers on both ends.

No matter if the 6200F is a VSX or a standalone switch, both do not work.

Did a bit of tinkering today. Yet no success.

What I did:

• Factory reset and reconfiguring the lag on 6200
• made interface on 8325 and 6200 a non lag
• using different port on 6200
• using different port on 8325
• using different transceiver on 8325
• using different transceiver on 6200
• directly attached 6200 to 8325 via one fibre cable -> instant connect even without lag on 6200
• attach different 6200 to questionable 6200 over fibre way - no connect

My guess is, that the problem occurs from our fibre infrastructure. The problem is, I have no clue why. We are currently using the infrastructure and it is working fine. The tranceivers also do not give any hints to what the problem could be.  No Errors and the Receiving and Transmitting power are within the recommended range mentioned in the spec sheet provided by HPE on both sides.

Any guess, what the problem could be or how we could identify it? Obvioulsy the fibre is working. Light is shining through.

Hi.

Looks like one of your fibre link is maybe on the edge of transceivers budget.  It can be problem in the panel and patch cables to just add enough loss to the signal to break connection. So you can try to clean the connectors on the panel and patch cables or you can ask for end2end measurements of affected line. 

As you wrote, there is instant connection if you connect directly so configuration looks ok. Looks much like line problem than anything else.

Best, Gorazd

I hope you can tell me, why I cant get a link between those.

Hello, 

for whatever reason I cant get a link between an Aruba 6200F and an Aruba 8325 over fibre.

The situation:

Both are lag and lacp active configured. I tripple-checked, if I swapped RX and TX. 

The tranceivers are on both ends J9150D and they see each other.

These are the configs:

Hi,

We also have the same problem, but I noticed that when the interface is taken out of the lag, the connection is established. If I put it back in the lag, the connection is disconnected. Therefore the transceiver cannot be defective.
