hp 5900 lacp to flex10 (link standby)

[drolfe]

HI,

I setup a single interface lacp between my hp 5900 switch to bay2 flex10 switche

Problem is the lacp link state stays as standby ?

I would have expected bay2 ports to go standby if I also had bay1 ports in the portchannel but this isn't the case

Config I used below:

[hp5900-irf] interface Bridge-Aggregation200
[hp5900-irf-Bridge-Aggregation-200] port link-type trunk
[hp5900-irf-Bridge-Aggregation-200] port trunk permit vlan 30
[hp5900-irf-Bridge-Aggregation-200] link-aggregation mode dynamic


[hp5900-irf-Ten-GigabitEthernet2/0/2] port link-mode bridge
[hp5900-irf-Ten-GigabitEthernet2/0/2] port link-type trunk
[hp5900-irf-Ten-GigabitEthernet2/0/2] port trunk permit vlan 30
[hp5900-irf-Ten-GigabitEthernet2/0/2] port link-aggregation group 200

Any ideas ?

Regards, Daniel

Do you have additional 5900 interfaces in the LACP group?

 - Do we take it as read that any additional interface has the precise same config as the config you've shown for int Te2/0/2

What about the flex10 switch config - what does that look like?

[drolfe]

HI,

Yes it's just the single 10g port for now in the port channel

the vc config is just a standard uplink set with the default setting

The reson for this single link uplink set is that I need vlan 30 to not be a private vlan on one blade servers but on all the others vlan 30 needs to be private.

Let me know if you need any other details

Also please see attached diagram

Existing LACP group br100

Ten1/0/1 => bay3 x3 (Active)

Ten2/0/1 => bay3 x4 (Active)

Ten1/0/2 => bay4 x3 (Standby)

New LACP group br200

Ten2/0/2 => bay4 x4 (Standby) ...!!??

I guess the question is: have you configured LACP on the physical ports on the FLex-10 module you've patched your switch to?

[drolfe]

HI, Yes I have, well it's done by default when you add interfaces into a "shared uplinkset"

Please see attached

The interface high lighted is the one I tried to put into a single interface prot channel by itself but it remained in link-standby

[Vince-Whirlwind]

OK, I was under the impression that it was when you add the ports in the Virtual Connect Manager that sets up the LACP. I was under the impression that the Shared Uplink Set relates to VLAN config, not link aggregation.

Regardless, that screenshot you've just attached shows that the Flex-10 side looks the way it is supposed to.

However, I am confused - it shows four "linked" links, and you're talking about a single link. ???

Going back to what you wrote earlier, I am now under the impression that you are trying to implement a *different* VLAN configuration on the Bay2 link from the VLAN config on the Bay1 link.

I think this might be the issue - I think the purpose of a "Shared Uplink Set" is to group links that have identical VLAN functionality?

So, I *think* that if you have differing VLAN requirements, you need to use different Shared Uplink Groups.

What do you think? I'm by no means an expert with these things - the only time I've had to deal with them, I was responsible for the ToR switches and the Data Centre guys drove the blade enclosure (via GUI, which I never understand very well) while I tried to figure out what they were doing.

[drolfe]

HI,

I beleive the comware side is all good.

I think the question is on the virtual connect (flex10) side of things:

1) Can I expect flex switch 2 (bay 2) in a c7000 chassis to privide active LACP status if the LACP group doesn't have any switch1 (bay1) ports ???

2) Will it work with a single interface in the LACP group ???

[drolfe · Accepted solution]

OK I got this working,

I changed two things and now the port is link-active

added vlan 1 (native vlan)

added stp edged-port

Full config below:

<HP-5900-Stack>dis cur interface br200
#
interface Bridge-Aggregation200
 port link-type trunk
 port trunk permit vlan 1 30
 link-aggregation mode dynamic
 stp edged-port
#
return
<HP-5900-Stack>dis cur interface Ten-GigabitEthernet 2/0/2
#
interface Ten-GigabitEthernet2/0/2
 port link-mode bridge
 port link-type trunk
 port trunk permit vlan 1 30
 port link-aggregation group 200
#
return
<HP-5900-Stack>

Link-agg info

Also see attached the VC is now happy

Are you sure you want that config? stp edged-port is normally only used for ports connected to end user equipment so the port will start forwaring quicker when it comes online. It is normally not used for ports connecting to other managed switches. How is STP configured on the Flex10?

[drolfe]

Hi,

AFAIK flex10 doesn't function like an actual switch and also doesn't run STP.

I got the stp edge-port config from the below site:

hp-virtual-connect-shared-uplink-set-configuration-with-hp-5900af-and-vsphere

Happy if someone can correct me on this but I seem to remember reading it somewhere.
