H3C <----> Procurve LACP configuration?

Vince_Whirlwind — Tue, 03 Sep 2013 21:59:11 GMT

I wonder if anybody has a working config for doing a LACP trunk between H3C & Procurve?

This is doing my head in.

My H3C config works fine H3C <----> H3C, but I can't seem to figure out how to configure it for a Procurve link.

H3C:

interface Bridge-Aggregation4
port link-type trunk
port trunk permit vlan all
link-aggregation mode dynamic

interface Ten-GigabitEthernet2/3/0/4
port link-mode bridge
port link-type trunk
port trunk permit vlan 1 4 9
port link-aggregation group 4

On the procurve side, I have a couple of problems.

Firstly, I can't seem to configure "trk1" unless it already has members.

But when I issue the command

trunk a1 trk1 lacp

It strips my VLAN config from the interface a1 and creates a trk1 without any VLANs on it, so I have no connectivity.

So, I add the required VLANs to trk1, but it won't allow me to re-add them to interface a1, which just has "untagged vlan 1" on it and I can't add VLANs to it. And I get no connectivity.

As this is a production system I get a very small window of opportunity to configure it and I can't have loss of connectivity while I fiddle. So I just need a working config I can slap on.

On the H3C side I get:

Local:
Port             Status Priority Oper-Key Flag
--------------------------------------------------------------------------------
XGE2/3/0/4       U       32768    9         {A}
Remote:
Actor            Partner Priority Oper-Key SystemID               Flag
--------------------------------------------------------------------------------
XGE2/3/0/4       45      0        290       0xab00, 78ac-c0d1-ab00 {ACEF}

But the Procurve tells me:

                                   LACP

          LACP      Trunk     Port                LACP      Admin   Oper
   Port   Enabled   Group     Status    Partner   Status    Key     Key
   ----   -------   -------   -------   -------   -------   ------ ------
   A1    Active    Trk1      Up        Yes       Success   0        290

and on the physical interface

Link Status : Up

So the H3C says "U", and I get no VLANs across the link despite the interfaces being up. And no LLDP. So it's not really "up" at all.

I'm starting to think that on the H3C, the "link-aggregation mode ..." should be something other than "dynamic", but "dynamic" is the only choice I get, so that can't be it.

Do it all the time, and "dynamic" is the correct setting for a BAGG to ProCurve switch.

On the ProCurve, configure the trunk first (trunk 23-24 trk1 lacp), then apply the VLANs, etc to the trunk (eg trk1).

Config Example extracts from recent show:

ProCurve 5406zl

interface E1 
   name "Link to 5830-IRF" 
exit
interface E2 
   name "Link to 5830-IRF" 

trunk E1-E2 Trk1 LACP

Comware 5830-IRF

#
interface Bridge-Aggregation5
 description Link to 5406zl
 port link-type trunk
 port trunk permit vlan all
 port trunk pvid vlan 930
 link-aggregation mode dynamic
 gvrp
#
#
interface Ten-GigabitEthernet1/0/52
 port link-mode bridge
 port link-type trunk
 port trunk permit vlan all
 port trunk pvid vlan 930
 port link-aggregation group 5
#
#
interface Ten-GigabitEthernet2/0/52
 port link-mode bridge
 port link-type trunk
 port trunk permit vlan all
 port trunk pvid vlan 930
 port link-aggregation group 5
#

Make sure you follow the order correctly:

Create BAGG
Set dynamic
exit
on each interface, set the aggregation group
exit
In the BAGG, apply the settings (trunk, VLAN, etc) so they are applied to the interfaces

Richard:

I have a similar scenario but my devices are an HP 5308xl and a HP a5120ei switch.

I am trying to create a trunk between these two switches using four ports on each end.

The 5308xl has a link that's connected to our servers and it is on a specific vlan.. eg: 10

Your configuration on the H3C switch shows "gvrp" towards the end..

I understand by reading hp's management guide for 5308xl, that you cannot use Dynamic LACP, if you want the LACP trunk to operate in a VLAN other than the Defaul VLAN... which is exactly my scenario.

Will this configuration work without causing other issues:

On HP 5308xl:

interface b15-b16
   name "Link to a5120ei" 
exit
interface d15-d16
   name "Link to a5120ei" 

trunk B15, B16, D15, D16 trk1 lacp

On HP A5120EI :

#interface Bridge-Aggregation1
 description Link to 5308xl
 port link-type trunk
 port trunk permit vlan 10
 link-aggregation mode dynamic
#
interface GigabitEthernet1/0/45
 port link-mode bridge
 port link-type trunk
 port trunk permit vlan 10
 port link-aggregation group 1
#
interface GigabitEthernet1/0/46
 port link-mode bridge
 port link-type trunk
 port trunk permit vlan 10
 port link-aggregation group 1
#
interface GigabitEthernet1/0/47
port link-mode bridge
port link-type trunk
port trunk permit vlan 10
port link-aggregation group 1
#
interface GigabitEthernet1/0/48
port link-mode bridge
port link-type trunk
port trunk permit vlan 10
port link-aggregation group 1
---------------------------------------

Could you please explain why you used the command - port trunk pvid vlan 930

Please let me know if my configuration would work..

And why did you use GVRP in your configuration...?

Suggestions are welcome.

Thanks!
