Hi - I have a bl860ci2 with 4 Cisco switches in the enclosure. Each pair of Cisco switches in configured in a "stack".
Our normal config on the servers is interfaces lanX and lanY on switch #1 configured as a LACP aggregate (e.g. lan900), and then interfaces lanA and lanB configured as another LACP aggregate (e.g. lan901) on switch #2.
We then create a failover group, lan902, made up of lan901 and lan902.
This has always worked and we've never had an issue...when these were set up as an "access" port so they could only be in one VLAN.
Now I have asked the network team to set these ports up as "trunk" ports so they support VLAN tagging...and its not working.
The LACP aggregates seem to create OK, but if I run lancheckconf I get this :-
ERROR: Ports 900 and 901 not connected
Some Fail-Over Group(s) in input file /etc/lanmon/lanconfig.ascii have verification errors.
I am using the standard lanconfig.ascii I always use which works everywhere else :-
LM_RAPID_ARP on
LM_RAPID_ARP_INTERVAL 1000000
LM_RAPID_ARP_COUNT 10
FAILOVER_GROUP lan902
PRIMARY lan900 5
STANDBY lan901 3
The network guys have checked and double checked and they say all is well from their side - so I am starting to wonder if this is something to do with supporting VLAN tagging/Cisco "trunk" ports via Lan Monitor or something like that.
Even more so as I also have a second set of NICS configured like this on the same server which are NOT VLAN tagged (just a standard Cisco "access" port) and that is working fine.
Any one get any insight? Thoughts?
Solved! Go to Solution.

Re: APA - LACP and LAN Monitor interface with a Cisco "trunk" port (for VLAN tagging).
Based on experience I would suggest to update LOM firmware, APA software and LAN drivers first.
LOM 50258
APA 11.31.60 (from software.hp.com):
HP-UX_11.31_for_IA_PA_J4240AA_B.11.31.60_HP-UX_B.11.31_IA_PA.depot
drivers:
HP-UX_11.31_10GigEthr-02_B.11.31.1205_HP-UX_B.11.31_IA.depot
Could you explain "not working"?
How does
# nwmgr
# nwmgr -S apa
# nwmgr -c lan900 [901/902] -v
# nwmgr -S apa -I 900 -v
... etc for 901/902
look like?
Hope this helps!
Regards
Torsten.

Re: APA - LACP and LAN Monitor interface with a Cisco "trunk" port (for VLAN tagging).
...thanks Torsten.
Everything now updated, or was already at the latest levels (e.g. APA).
Output requested is below.
So, lan905 (which is a lan monitor of lan903 and lan904, which are LACP aggregates) is fine. On the Cisco side, it is an "access" port allowing only one VLAN - and the IP assigned to lan905 works.
On lan902 (which is a lan monitor of lan900 and lan901, which are LACP aggregates) I dont get any network connectivity when I assign the correct IP. This is a Cisco "trunk" port allowing multiple VLANs. (This will be an IVM host so I need multiple VLANs for various guests...)
When I start hplm, I do see this error though which I'm sure is relevant! -
WARNING: Failed link-level connectivity checks for ports in Fail-Over Group 902.
For more information, see nettl log messages for HP_APA.
Also, once hplm is started, a few moments after I see this on the console :-

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To eliminate the lan monitor piece, I have also tried to directly configure lan900 with an IP and even though the LACP aggregate looks OK in nwmgr, I still dont get any network connectivity...so its nothing to do with the lanmonitor piece.
I would love to say this was a network config issue, but I'm no expert at all and the network team tell me it OK.
I just dont know why a "trunk" vs. an "access" (Cisco speak) would make any difference.

Re: APA - LACP and LAN Monitor interface with a Cisco "trunk" port (for VLAN tagging).
We had a similar setup and a strange behaviour after starting to update firmware, software, etc.
The lan900 trunk did not longer form, adding lan17 to aggregate lan904 failed:
# nwmgr -s -S apa -I 17 -A key=904 -A mode=LACP _AUTO
lan17 new values:
Key = 904
Mode = LACP_AUTO
# nwmgr -S apa
Class Mode Load Speed- Membership

======== =========== ========= ==================== ===========================
lan13 LACP_AUTO - 1 Gbps Full Duplex -
lan17 LACP_AUTO - 1 Gbps Full Duplex -
...
lan904 Not_Enabled LB_MAC 0 Mbps -
...
Finally it turns out the reason was a incorrect switch port setting, but the older combination of firmware+software did not check that. So it looks like working.
After correcting the switch setting it really worked.
So the reason for your problem was a switch setting too?
Hope this helps!

Torsten.

Hello,
Can you tell me what was the network configuration required to make LACP working ?

Re: APA - LACP and LAN Monitor interface with a Cisco "trunk" port (for VLAN tagging).
Hi Graham,
Greetings !!!
I am also facing the same issue as you mentioned. It shows the same error - lan900 and lan901 are not conencted.
ERROR: Ports 900 and 901 not connected
Some Fail-Over Group(s) in input file /etc/lanmon/lanconfig.ascii have verification errors.
Could you please let me know what was the solution. Is there something that we want to change in the switch side.
Also, is there any way that if any one of the network port in the active group (eg. lan2 of lan900) fails, it can fail over to the other group 901. Please let me know.
Thanks,
Umesh
