Loosing BAGG When assigning New VLAN 5900AF

Hello,

I'am facing a very strange issue.
I have 2 IRF Stacks based on 2 paris of 5900AF Switchs.
Theses stacks are used for theVMware Datacenter connectivity.
To connect to my Backbone Switches i have created a BAGG composed of 4 ports.
Everything is working as needed but when i add a new VLAN in the Switch i loose the connectivity of the BAGG.

To reestablish the connectivity i have to unplugg all the BAGG cables ans reconnect them.
The remote Backbone Switch is a single HP Procurve 2910al.

How can you explain this behavior?
It seems to happen only when i assign an IP to the VLAN.

Thanks for your help.

Re: Loosing BAGG When assigning New VLAN 5900AF

It's unclear.

You wrote you have a setup with two IRF Stacks, each one made of two 5900AF Switches (a total of four 5900AF Switches). That's OK.

Hope I've misunderstood your scenario...but you wrote that you have Backbone Switches (so plural) connected to both your IRF Stacks but you just cited one single remote Backbone Switch (an HP ProCurve 2910al)...that let me think you should have two separate Port Trunk Groups (using the HP ProCurve terminology) definded on the 2910al and each Port Trunk Group (made of aggregated interfaces) separately terminates on each IRF Stack...in other words...from what you wrote...it seems that each IRF Stack has a LAG (Link Aggregatation Group, Comware terminology) that terminates on the 2910al, exactly on each Port Trunk Group counterpart...a scenario that is totally understandeable.

If this is not the case it means that your scenario has instead a single Port Trunk on the 2910al side that is necessarily "distributed" against both two separate IRF Stacks...but I think that scenario is not supported (a Port Trunk splitted to two separate LAGs).

So:

  1. How is your exact network topology with regard to the HP ProCurve 2910al and two separate 2 members IRF Stacks?
  2. Where you "created a BAGG composed of 4 ports."?
  3. Where the above 4 ports BAGG terminates?
  4. Are the IRF Stacks directly interconnected together (other than being indirectly interconnected through the 2910al)?
  5. What is the VLANs status/configuration on IRF Stacks and on the 2910al?
  6. Have you more than one 2910al (the Backbone Switch)?

You then wrote "when i add VLAN in the Switch...", which one?

P.S.

The output of those CLI commands would help:

On ProVision based Switches (HP ProCurve): show trunks and/or show lacp

On Comware based Switches (5900AF): display link-aggregation verbose

Moving this whole threat to the Comware-based category would help (Web and Unmanaged doesn't fit well speaking about 2910al and 5900AF).

Re: Loosing BAGG When assigning New VLAN 5900AF

Thanks for your quick reply Parnassus!

Sorry for my bad explanation. My 2 IRF Stacks are totaly seprated. I have two production sites with the same IRF topology on each site.

I have made a quick plan to explain you the topology (attached JPG).
Below you will find the results of the cli commands that answers the other questions.

I don't Know how to move this thread to the Comware-based Category. Sorry ;-)

Hope this helps to Understand my topology.

Re: Loosing BAGG When assigning New VLAN 5900AF

OK, better now.

A first thing that can be noticed looking at BAGG50 status on the IRF Stack:

Aggregate Interface: Bridge-Aggregation50
Aggregation Mode: Dynamic
Loadsharing Type: Shar
Management VLAN : None
System ID: 0x8000, e8f7-2431-1ef9
Local:
  Port             Status  Priority Oper-Key  Flag
--------------------------------------------------------------------------------
  XGE1/0/47        U       32768    1         {A}
  XGE1/0/48        S       32768    1         {ACDEF}
  XGE2/0/47        S       32768    1         {ACDEF}
  XGE2/0/48        S       32768    1         {ACDEF}
Remote:
  Actor            Partner Priority Oper-Key  SystemID               Flag
--------------------------------------------------------------------------------
  XGE1/0/47        17      0        103       0xf840, 2c27-d77b-f840 {ACEF}
  XGE1/0/48        20      0        103       0xf840, 2c27-d77b-f840 {ACDEF}
  XGE2/0/47        18      0        103       0xf840, 2c27-d77b-f840 {ACDEF}
  XGE2/0/48        19      0        103       0xf840, 2c27-d77b-f840 {ACDEF}

is that port XGE1/0/47 state is Unselected (U): this means that traffic coming from the Trk50 (2910al) on the same link (so from Port 17, see indeed Partner 17) will be dropped and this is not a good thing to start with.

This situation can be observed looking at the Trk50's Port 17 status as reported here:

        LACP      Trunk     Port                LACP
   Port   Enabled   Group     Status    Partner   Status
   ----   -------   -------   -------   -------   -------
   13     Active    Trk41     Down      No        Success
   14     Active    Trk41     Down      No        Success
   15     Active    Trk41     Down      No        Success
   16     Active    Trk41     Down      No        Success
   17     Active    Trk50     Blocked   Yes       Failure
   18     Active    Trk50     Up        Yes       Success
   19     Active    Trk50     Up        Yes       Success
   20     Active    Trk50     Up        Yes       Success
   21     Active    Trk1      Blocked   No        Failure
   22     Active    Trk1      Up        Yes       Success
   23     Active    Trk1      Up        Yes       Success
   24     Active    Trk1      Up        Yes       Success

So this is a thing that need, in my opinion, to be investigated further.

Then, and there could be a strict relationship with the BAGG50<-->Trk50 non good status reported above, another thing to notice is that VLAN IDs assignment on BAGG's member interfaces (not directly on BAGG itself) has an anomaly [**] exactly regarding the XGE1/0/47; looking at VLANs defined on the IRF Stack BAGG50 - and so its XGE1/0/47, XGE1/0/48, XGE2/0/47 and XGE2/0/48 member interfaces [*] - permits those tagged VLAN IDs: 300, 700, 701, 702 and 901 BUT Interface XGE1/0/47 - it very alone - is also tagged for VLAN IDs 100, 101 and 200 which is pretty strange since, being a member of BAGG50, it should have the same exact settings of other three member interfaces with regard to VLAN IDs tagging (this other than all other physical interface settings, which I presume already OK); interfaces XGE1/0/48, XGE2/0/47 and XGE2/0/48 aren't tagged on VLAN IDs 100, 101 and 200 exactly as it isn't the whole BAGG50 for those VLAN IDs.

See what I mean here:

Removing XGE1/0/47's VLAN tagging on VLAN IDs 100, 101 and 200 would help in fixing things.

[*] indeed if BAGG50 is tagged on some VLAN IDs so are there its member interfaces.

[**] BAGG configuration on Comware requires to configure all at BAGG level (then configuration - VLAN IDs tagging included - are going to be propagated down to BAGG member interfaces automatically).

This just looking at IRF Stack <--> 2910al interconnection.

To check BAGG50 interface members' status on IRF Stack side, perform:

display interface brief | include 1/0/4[7-8]

display interface brief | include 2/0/4[7-8]

Re: Loosing BAGG When assigning New VLAN 5900AF

Hello Parnassus,

I have to correct this mistakes but i have to make that on site.
In the meantime i have checked my other site that have the same configuration and the same issue.
I don't have this mistakes (if i have understood well) on this config so it's not the source of the loosing BAGG.

Here are the config:

Re: Loosing BAGG When assigning New VLAN 5900AF

Hi, I never wrote that what I found in your first site configuration you gave was the culprit of your issue...it's just a thing I noticed and a thing to investigate on further.

Glad your second site shows no issue on the BAGG link as the first site (even if it shows the same issue related to VLAN addition you reported the first site has).

At this point would be important to exactly explain what happen. You initially wrote:


idinfo wrote: Everything is working as needed but when i add a new VLAN in the Switch i loose the connectivity of the BAGG. To reestablish the connectivity i have to unplugg all the BAGG cables ans reconnect them.

but you still haven't described what you did (...when i add a new VLAN in the Switch...), on which switch(es) you did that and what logs were generated when you did that VLAN related configuration.

Are you using only Port based VLANs or are you also routing among (IP-based) VLANs? and, if so (so there are Protocol based VLANs too), which switch is actually performing the IP Routing task?

Perform a dispaly vlan vlanid on the IRF Stack for each vlanid (VLAN ID) you have definded on the IRF Stack, repeat the same on the Switch you use on the Backbone (something like show vlans vlanid), this to have a full idea of your VLANs configuration IRF Stack side and Backbone Switch side.

Re: Loosing BAGG When assigning New VLAN 5900AF

Hi,

Sorry for my bad english, that's not my intention ;-)

This is the steps that lead to BAGG breaking:

  • Adding the VLAN to the Backbone Switch (2910) => No Impact
  • Tagging all the needed ports (including BAGG) with the new VLAN on the Backbone Switch (2910) => No Impact
  • Adding an IP to the Backbone Switch (2910) => No Impact
  • Adding the VLAN to the IRF Stack (5900AF) => No Impact
  • Tagging all the needed ports (Include BAGG50) with the new VLAN on the Backbone Switch (5900AF) + Adding an IP to the Backbone Switch (5900AF) => BAGG Down

2017-09-01 10_05_02-HPE 5900AF-48XGT-4QSFP+ Switch_Dashboard.png

I have to check if it's "Assigning the VLAN" or "Setting the IP to the VLAN" that Pull Down the BAGG.
I will check that Friday when i will correct the mistakes that you have detected.

Sorry again and thanks for your precious help.

Re: Loosing BAGG When assigning New VLAN 5900AF

Hi,

Here is the results of the tests ans checks:

Are you using only Port based VLANs or are you also routing among (IP-based) VLANs? and, if so (so there are Protocol based VLANs too), which switch is actually performing the IP Routing task?
Only Port-Based VLANs. IP Routing is disable on all Switchs.

Perform a dispaly vlan vlanid on the IRF Stack for each vlanid (VLAN ID) you have definded on the IRF Stack, repeat the same on the Switch you use on the Backbone (something like show vlans vlanid), this to have a full idea of your VLANs configuration IRF Stack side and Backbone Switch side.
The two Sides seams to be correct for the VLANs.

I have corrected the port Tagging on port 47 and now i have all my trunks valid.

I have made my tests this morning and i was not be able to reproduce the issue.
The only difference was that i have made my changes directly connected to the IRF Stack (not remotely) and corrected the mistake of port 47.

Hope the issue is solved. I will try next time remotely and not remotls to check if it's the source of the issue but i dont mind it this.

Thans for your help
