Wired Intelligent Edge

Hello Community,

we have massive performance issues at one of our customers sites.

Setup is shown in PDF-doc attached

All switches are interconnected with LACP Trunks at 2GBit/s

There are multiple VLANS

QoS -DSCP

Voice

LLDP-MED

Problem is:

When we copy Data from one host to another we get transfer rates about max. 160Mbit.

The two hosts are on the same switch and they are both connected at 1000FDx.

Also when the two hosts are on different switches, the transfer rate is about 120Mbit

Some config:

hostname "DV1SW1"
module 1 type j9728a
trunk 43-44 trk1 lacp
trunk 45-46 trk2 lacp
trunk 47-48 trk3 lacp

other Configs are pretty much the same ...

we have no idea what we've done wrong..

Many thanks for some help ...

Hello community,

any ideas ?

Thanks in advance ,

Cheers,

HI all,

unfortunally nobody replied to the thread.

That's very sad :-(

no matter what, we kind of solved the Problem.

Solution:

1. We've had multiple STP.Root changes .

Set up a MSTP Configuration ported all other switches to mstp.

select one switch to become root of the vlans of an mstp instance.

Made the root-history a lot smaller.

2. we had some trouble with jumbo-frames

Enable jumbo on data vlan did the trick

3.  for some reason the LACP trunks to the NAS didn't work.

Ugrading to the newest beta-release of HP-OS did the trick.

Some clients have had bad MTU values due to installing IPSEC-Clients (e.g. Cisco, LANCOM, etc.)

So finaly a nice mix of stupid failures made me sleep very bad ...

show tech all ...  a lot of time ... solution found.
