Enabling Link aggregation on a procurve switch

[peterthorn]

I have a ProCurve 2848 switch and I would like to get link aggregation to work. The switch has been updated with the newest firmware, which is supposed to support it. However the server states that it isn’t configured to enable link aggregation.
When I have asked in procurve forums they talk about port trunking – but in the article here on afp548 (https://www.afp548.com/article.php?story=20060724001126511) it seems that some has managed to do it without doing major configuration on the switch – has anyone any good input? (I have looked in the online manuals, but they seems only to cover much more advance setups with multiple switchs etc – we have only one vlan and one switch.

TIA,
Peter

My problem is that I’m not sure if it is possible to enable lacp just like that…
It seems to me that I have to select the ports on the switch, trunk them and then enable them – but if it is possible to just activate lacp without trunking etc. I would prefer that.

Thanks,
Peter

I managed to to make lacp active via the telnet command
int e 1-44 lacp active
I figured that I might as well make all the ports active, as no other switches are present, so it shouldn’t be a problem. And when I run the command show lacp, all the ports is registered as active.
But when I look in the status of the network on the server, it still doesn’t work – see the error http://www11.dht.dk/~spildaftid_dk/error.png – it seems that there is a connection, but I don’t get the No Partner part.

Any ideas?
Thanks,
Peter

Just to follow up with the solution, so others might use it:
– first telnet to the switch
– then enter config mode by writing “config”
– activate lacp on the appropiate ports eg. “int e 33-34 lacp active” (which obviously is activation for port 33 and 34)
– check that it works by writing “show lacp” which should list if the port is active or passive.

That’s it – no need for manual trunking.
