  • 1.  2-member VSF stack 40 Gbps LACP

    Posted Sep 19, 2018 07:26 PM

    Hello,

     

     

    Screen Shot 2018-09-19 at 20.20.43-1.png

     As per screenshoot attached, I would like to setup LACP (at 40 Gbps) using these DACs. I have configured a single lacp with 4 interfaces on ArubaOS (2930F) side and a single Bridge Aggregation with 4 interfaces on Comware side (5940).

     

    I've got a BridgeAggregation 1 on IRF Stack - the four ports (5940 2slot);

    Aruba = trunk 10 1/49-1/50 2/49 2/50 lacp

     

    For now I could only get to work two links (1/49 and 1/50) and the configuration seems correct.

     

    Is there anything that I am missing here?

     

    Info#1: There DACs are HPE(Comware) 5 m. I can see some CRC erros.crc error.jpeg

    Can you provide SKUs of all used DAC Cables?

    Are they 1 meter long?

    Can you share (sanitized) running configuration of IRF and VSF?

    Also outputs of display link-aggregation verbose and show lacp CLI commands would be of help.

    Are they 1 meter long?

     

    They are 5 meters long. Is that a issue?

     

    JG081C HPE FlexNetwork X240 10G SFP+ to SFP+ 5m Direct Attach Copper Cable

     

    I'm going to run all the commands and post here ASAP.

    No, not in your specific case (https://support.hpe.com/hpsc/doc/public/display?sp4ts.oid=null&docLocale=en_US&docId=emr_na-a00056174en_us).

    It looks like that JG081C isn't among 1, 3 and 7 meters long DAC SKUs supported by various Aruba Switch series, Aruba 2930F included.

    The LACP is working right now. Not sure exactly why, but the customer rebooted the swithes, but the second VSF link is out. Weird.

     

    First try:

    Aruba01(config)# vsf member 1 link 1 1/51-1/52
    All configuration on this port has been removed and port is placed in VSF mode.
    Aruba01(config)# show run interface 1/52

    Running configuration:

    interface 1/52
       untagged vlan 1
       exit

     

    Second try:
    Aruba01(config)# vsf member 1 link 1 1/52
    All configuration on this port has been removed and port is placed in VSF mode.
    Aruba01(config)# show run interface 1/52

    Running configuration:

    interface 1/52
       untagged vlan 1
       exit

     

    Aruba01(config)# show vsf link

     VSF Member 1

                      Link     Peer   Peer
     Link Link-Name   State    Member Link
     ---- ---------- -------- ------ ----
     1    I-Link1_1   Up       2      1
     2    I-Link1_2   Down     0      0


     VSF Member 2

                      Link     Peer   Peer
     Link Link-Name   State    Member Link
     ---- ---------- -------- ------ ----
     1    I-Link2_1   Up       1      1
     2    I-Link2_2   Down     0      0

     

    VSF CONFIG
       enable domain 1
       member 1
          type "JL254A" mac-address 98f2b3-bcb780
          priority 128
          link 1 1/51-1/52
          link 1 name "I-Link1_1"
          link 2 name "I-Link1_2"
          exit
       member 2
          type "JL254A" mac-address 98f2b3-bc4840
          priority 128
          link 1 2/51-2/52
          link 1 name "I-Link2_1"
          link 2 name "I-Link2_2"
          exit
       port-speed 10g
       exit

     

    Also, I've seem some CRCs errors (LACP port that use the DAC Cable 5 meters).

    Greetings!

     

    VSF link 2 shows Down on each member because there are no ports assigned to link 2 on either chassis — both physical VSF ports on both members are assigned to link 1.

    Thanks for the reply.

     

    Shoud I create the link 2? I've just got two dacs for VSF. Whats the best design?

     

    vsf
       enable domain 1
       member 1
          type "JL254A" mac-address 98f2b3-bcb780
          priority 128
          link 1 1/51

          link 2 1/52
          link 1 name "I-Link1_1"
          link 2 name "I-Link1_2"
          exit
       member 2
          type "JL254A" mac-address 98f2b3-bc4840
          priority 128
          link 1 2/51

          link 2 2/52
          link 1 name "I-Link2_1"
          link 2 name "I-Link2_2"
          exit
       port-speed 10g
       exit

     

     EDIT: I understand that the LINK 2 is for the 3º and 4º switches.

    That's correct. A second VSF link could be used for redundancy if you had a second 40G module (it has to be the same speed as the first VSF link), but for a two-switch stack, as long as one VSF link is up the fabric will operate normally.
