HP 3800 trunk creating General error

[RenarsK]

Hi All!

I started to configure my new 3800 switchee and stuck with trunk problem - switch don't allow me to create static LACP trunk. Executing trunk command: "trunk 1-3 trk1 lacp" I receive "General error."

What I was dong wrong or what is wrong with switch:

Here is my current trunk configuration - one Dyn1 LACP created:

Switch_Edge_1# show lacp

                                   LACP

          LACP      Trunk     Port                LACP      Admin   Oper
   Port   Enabled   Group     Status    Partner   Status    Key     Key
   ----   -------   -------   -------   -------   -------   ------  ------
   51     Active    Dyn2      Up        Yes       Success   500      500
   52     Active    Dyn2      Up        Yes       Success   500      500


Switch_Edge_1# show trunks

 Load Balancing Method: L3-based (Default), L2-based if non-IP traffic

  Port   | Name                             Type      | Group  Type
  ------ + -------------------------------- --------- + ------ --------
  51     |                                  SFP+DA7   | Dyn2   LACP
  52     |                                  SFP+DA7   | Dyn2   LACP

Ports I want to use for trunk:

Switch_Edge_1# show interfaces brief 1-5

 Status and Counters - Port Status

                         | Intrusion                           MDI  Flow Bcast
  Port         Type      | Alert     Enabled Status Mode       Mode Ctrl Limit
  ------------ --------- + --------- ------- ------ ---------- ---- ---- -----
  1            100/1000T | No        Yes     Down   1000FDx    Auto off  0
  2            100/1000T | No        Yes     Down   1000FDx    Auto off  0
  3            100/1000T | No        Yes     Down   1000FDx    Auto off  0

And finnaly trunk command used:

Switch_Edge_1(config)# trunk 1-3 trk1 lacp
Operation failed on Port 1: General error.
Switch_Edge_1(config)#

In attached file is also current running switch configuration.

What should I do to creat static LACP trunk?

Thank you, Renars

Hi Renar,

Do you get teh same error if you try to trunk up 2 ports? What about if you pick 2 other ports to trunk (8 & 10 for example)?

[RenarsK]

Hi Chris,

yes I tried different ports and even different static trunk types - every time I receive General error :(

I can't create static trunk at all, only was lucky with dynamic trunk, as you can see in running config.

Here some of options I tried:

Switch_Edge_1(config)# trunk 2,3 trk1 lacp
Operation failed on Port 2: General error.
Switch_Edge_1(config)# trunk 3,24 trk19 lacp
Operation failed on Port 3: General error.
Switch_Edge_1(config)# trunk 3,24 trk19 trunk
Operation failed on Port 3: General error.

Is this switch stacked at all?

[RenarsK]

Hi Matcol,

no this switch is standalon and not part to stacked enviroment. Why is that important?

[Matcol]

Sometimes you  might forget that it it's not port 1, but port 1/1, that's all.

I can't see the switchport config in your config - can you add some config to the ports to make them appear, like "auto-1000" or something maybe?

[RenarsK]

Found out that there was some switch internal problems. Most likely coused after switch firmware update.

I reset switch to factory default (erase startup-config) and all problems gone.

It looks like you had dynamic trunks (Dyn2) rather than static (Trk2).

Try "no int 52 lacp".
