Bridge Port Data Units (BPDU) Filter and Link Agregation Control Protocol (LACP) questions?

Andre is helping a customer that is connecting Virtual Connect to a Cisco Nexus switch:

Hi guys,

This is the last configuration of the customer on the Nexus :

Eth10/30      vs HP_prod. Cloud  connected trunk     full    10G     10Gbase-SR

Eth10/31      vs HP_prod. Cloud  suspnd    trunk     full    auto    10Gbase-SR

interface port-channel10

  description LAG HP_prod. Cloud Engine

  switchport

  switchport mode trunk

  spanning-tree port type edge trunk

interface Ethernet10/30

  description vs HP_prod. Cloud Engine

  switchport mode trunk

  channel-group 10 mode active

  no shutdown

interface Ethernet10/31

  description vs HP_prod. Cloud Engine

  switchport mode trunk

  channel-group 10 mode active

  no shutdown

Debug LACP

2012 May  8 20:11:45.284731 lacp: lacp_proto_get_state(731): IF Ethernet10/30(0x1a49d000): end PartnerEnd(2): state TimeOut(1): enable_flag True

The problem is that the VC doesn’t answer to the LACP request, the firmware of the VC is 3.18 because the customers had urgency to go in production, but I think it’s not the problem.

Look at this guide: http://h20000.www2.hp.com/bc/docs/support/SupportManual/c02656171/c02656171.pdf

As per the guide, have you tried:

- LACP rate Fast?

- Reviewed the Cisco fw?

interface port-channel10

  description LAG HP_prod. Cloud Engine

 LACP rate Fast

  switchport

  switchport mode trunk

  spanning-tree port type edge trunk

interface Ethernet10/30

  description vs HP_prod. Cloud Engine

  LACP rate Fast

  switchport mode trunk

  spanning-tree port type edge trunk

 channel-group 10 mode active

  no shutdown

interface Ethernet10/31

  description vs HP_prod. Cloud Engine

  LACP rate Fast

  switchport mode trunk

  spanning-tree port type edge trunk

  channel-group 10 mode active

  no shutdown

Any other suggestions?

That was the answer I needed.

I’ve been on site and I verified a cabling problem (exchanged 2 VC cables directed to different Nexus).

Now everything works.
