Configuring 5930 to work with a Dell FN410T switch

Hi,

We are currently trying to get LACP configured from our Hp5930s to a Dell FN410T switch. I don't think it's working correctly.  Below is what we have configured.

HP 5930:

interface Bridge-Aggregation6 (This is our BAGG)
 description HYPER-V CLUSTER LINK 1
 port link-type trunk
 port trunk permit vlan all
 port trunk pvid vlan 14
 link-aggregation mode dynamic

interface Ten-GigabitEthernet1/2/7 (We are using 6 interfaces. 1/2/7,9,11 and 2/2/7,9/11.  They are all the same)
 port link-mode bridge
 description FX-FX2 HYPER-V CLUSTER 1
 port link-aggregation group 6

-------------------

Dell FN410T

interface TenGigabitEthernet 0/10 (There's 3 interfaces total: 10, 11 ,12)
 description HP5930
 no ip address
!
 port-channel-protocol LACP
  port-channel 10 mode active
!
 protocol lldp
 no shutdown

interface Port-channel 10
 no ip address
 portmode hybrid
 switchport
 vlt-peer-lag port-channel 10
 no shutdown

 

When I do a dis link ver I get:

Aggregate Interface: Bridge-Aggregation6
Aggregation Mode: Dynamic
Loadsharing Type: Shar
Management VLAN : None
System ID: 0x8000, 2c23-3aaa-907c
Local:
  Port             Status  Priority Oper-Key  Flag
--------------------------------------------------------------------------------
  XGE1/2/7         U       32768    3         {AG}
  XGE1/2/9         U       32768    5         {AG}
  XGE1/2/11        U       32768    5         {AG}
  XGE2/2/7         U       32768    5         {AG}

--------------------------------------------------------------------------------
  XGE1/2/7         0       32768    0         0x8000, 0000-0000-0000 {EF}
  XGE1/2/9         0       32768    0         0x8000, 0000-0000-0000 {EF}
  XGE1/2/11        0       32768    0         0x8000, 0000-0000-0000 {EF}
  XGE2/2/7         0       32768    0         0x8000, 0000-0000-0000 {EF}
  XGE2/2/9         0       32768    0         0x8000, 0000-0000-0000 {EF}
  XGE2/2/11        0       32768    0         0x8000, 0000-0000-0000 {EF}

As you see, the are unselected and when I display the interface, the ports are down.  I've been scratching my head and Dell won't assist since it's not a branded switch.  Any assistance is greatly appreciated.

Better if you start with a basic drawing of your network, limited to all involved Switches and their (inter)links (so at least with your HPE 5930 and the Dell FN410T)...it's not clear why on the Dell you have a BAGG with only 3 members ports (10|11|12) and then on the 5930 you used 6 (XGE1/2/7|9|11 and XGE2/2/7|9|11)...

Re: Configuring 5930 to work with a Dell FN410T switch

I thought I mentioned that I'm using 6 interfaces on my original posting. To iterate, we have 2-HPE 5930 switches, stacked, and it connects to 2-Dell FN410T switches.

On the HP side, I am using ports 1/2/7, 9, 11 and 2/2/7, 9, 11

On the Dell side, I am using ports 10, 11, 12 on both switches.

Dell has preconfigured the ports with the configuration above.  I'm trying to get LACP working on our side but I'm coming to dead ends.

Re: Configuring 5930 to work with a Dell FN410T switch

Sorry if I iterate it too...on the Dell side are those two Switches acting and behaving like a single logical entity (Virtual Switch) or what?

If your two HPE 5900 Switches are "stacked" (do you mean that IRF was deployed?) then they act as a single logical entity (Virtual Switch) when seen by other Switches.

So are you trying to set up a double Port Trunks (aggregation protocol: LACP): one 3 ports Port Trunk between Dell Switch 1 to IRF Stack, one 3 ports Port Trunk between Dell Switch 2 and the IRF Stack...or are you trying to deploy two concurrent and separated Port Trunk(s) - 3 ports each - from a Dell Switch Stack (Virtual Switch) to the IRF Stack (Virtual Switch)? this one will be a loop...

If Dell Switches are not interconnected together (by means of a simple/aggregated Trunk or by means of any Virtual Switching technology Dell would support) then your two Port Trunk(s) should be OK - and it will be a matter of configuration check on LAGs - because the separated Trunks will terminate on separated Switches (so no loop).

On the 5930, the BAGG is where you do all of the configuring. The individual ports should look just like the BAGG they are connected to.  That port looks like it is missing most of the configuration.  You might want to remove and re-associate the individual ports to the BAGG and see if the BAGG configuration gets pushed down to the individual ports.

Hi,

Not sure whats going on here. It is apparent that your two HP5930s are IRF stacked.

But how are your dell switches connected? (both interconnection if so, and the connection to the HP IRFstack)

Is it (A):

- two independent switches with 3 interfaces in thier port channels?

or is it (B):

- a stack (using some DELL stacktechnology - ie. one controlplane) having 6 interfaces in the link-aggregation?

If (A) then you need to consider some loop prevention (if the DELLs are in some way interconnected) and you might want to have two BAGGs (one to each DELL) .

If (B) then you're good. You could try clearing the bagg:

undo interface bri 6
interface bri 6 
 link-aggregation mode dynamic
 quit
interface range te1/2/7 te1/2/9 te1/2/11 te2/2/7 te2/2/9 te2/2/11
 port link-aggregation group 6
 quit
interface bri 6 
 description HYPER-V CLUSTER LINK 1
 port link-type trunk
 port trunk permit vlan all
 port trunk pvid vlan 14
 quit

Regards
