Port trunking.

[BOVC]

Hi there,

We have a couple of VMware server running, and I want to bundle 3 gigabit connections to each server.
Now, this has already been done on the VMware servers, but when I try to trunk the links on the switch (ProCurve 5406zl - v11.33) it tells me that it is not possible for the selected ports.
I read about trunking in the HP manual, and set up the ports with static speed/duplex on the VMware, and 1000/auto on the switch. For some reason I cannot select 1000/full???

Anyway, the situation is the same... I don't get to trunk the ports (which by the way is 1GB cobber).

Any clues?

Thanks in advance,
Rasmus

It should be really straight forward.

e.g.
5406(config)# trunk a1-a3 trk1

There should be no need to change the port settings from the default of Auto.

If you're still having difficulties can you attach your switch configuration here (remove any sensitive info like public IP's and SNMP community names). And advise which ports it is that you're trying to trunk.

OK here goes...

You currently have 3, 2-port trunks configured:

trunk C21-C22 Trk1 Trunk
trunk C23-C24 Trk2 Trunk
trunk D21-D22 Trk3 Trunk

Do you need to have 3 port trunks configured instead? e.g.

trunk C21-C23 Trk1 Trunk

You may need to first remove the existing trunk, and then reconfigure them this way if that is the case.

Oops, sorry... Forgot to include the details :)

The existing trunks are fiber and are not part of this issue.

The ports that I want to configure trunking on, are e.g. A4,A5,A7 as one trunk, and C1,C2,C3 as another. They are all gigabit cobber links.

This is the exact error I get:

5406_ServerRoom(config)# trunk d1 trk20 trunk
Operation failed on Port D1: General error.
5406_ServerRoom(config)#


What the #¤/&% is going on?

Hi,

this post is a little bit outdated, but I have a similar error. I want to combine to ports (B17,B18) into a trunk, but I always get "General error".

@Rasmus: Did you solve your problem? And if yes, how?

Hi

I get the same "general erro"r when configuring LACP trunking on a HP5406

to a Proliant dl380 Gen8. Does anyone know how to solve this., Gary

Hello,

the thread is a little bit old but I found the solution. (Actually I found the solution soon after my initial post, but everytime I remebered to post the solution I was unabled to do so.)

The "General error" occurs if there are some settings in the config that refer to any of the interface names that are going to be part of the trunk and therefore will become inaccessible as an interface of its own.

For example, if one want to create a trunk Trk1 made up of A1 and A2. Then there must be no setting that refers to interface A1 or A2, because if the trunk was created, A1 and A2 are no longer valid interface names.

In my case, the offending settings were "ipv6 ra-guard" and "dhcp snooping".

Unfortunately it is not enough to use "show running-config interface <iface name>" in order to find these settings, because they are not displayed there.

The most simple solution I found is to dump the whole config (show running config) and then search the output for any occurances of the port names involved.

Good places to look for are:

ipv6 ra-guard

dhcp snooping

port-security

port-access
