How do I switch a HP Procurve switch to IGMP v3?
I have a HP 2530 24G switch that I'm trying to get into ICMP V3 mode. Trying the command: <ip igmp lookup-mode ip> it tells me it's invalid. I don't see any igmp commands that allow me to switch versions despite having version YA.16.05.0008 of firmware and the manual showing that I can configure this. Any ideas?

I have confirmed the switch is booting into YA.16.05.0008
IGMP is enabled on the vlan I'm working with. That being said there are specific commands I see in the cli reference to change the IGMP to version 3 yet I do not see those options being available.

IGMP v1 = plain old IGMP only support subscribe, after a certain time it expires until renewed (possibly to sending multicast to some place after it isn't needed.
IGMP v2 = IGMP v1 + UNSUBSCRIBE....
IGMP v3 if IGMP v2 + extended subscriptions depending on source..., it mostly requires support for the source of multicasts ....
(A switch more or less only looks at passing IGMP (or not.. depending on config) and then selects a port that subscribes as a target for specific streams). This option was mostly called IGMP Snooping. (As the switch is only optimising the results for non participating ports.)
I didn't find the documentation for that version, only parts for WB (29xx switches) firmware. wasn't it stated that the switch supports IGMP up to V3?

It's spoke about here: https://support.hpe.com/hpesc/public/home/documentHome?docId=emr_na-a00038747en_us&sp4ts.oid=1009060825. There is discussion about switching the switch to version 3 specifically and moving the switch to IP mode, not MAC mode which is required.
I have been reading this
igmp IP lookup-mode is for both igmp v2 and igmp v3..., where igmp v2 can also work in mac mode.
(If a router announces IGMP v2 packets the whole lot works in IGMP v2 anyway.)
in config mode? (conf t)
(I did miss the procurve line was partly renamed to Aruba...., that why i missed this version.)

Exactly. I've gone into config mode and used what should have allowed me to enter IGMP 3 mode:
ip igmp lookup-mode ip
subsequently ip igmp version 3 in a vlan context
Both are invalid. Furthermore when I type ip in a root context I get no options for IGMP. When I type ip igmp in a vlan context - I only get a limited set of options that have nothing to do with versions.
ip igmp lookup-mode ip
subsequently ip igmp version 3 in a vlan context

This is something for the HPE support...., not working as documented..., i have noticed HP getting sloppy on details in the last years. Seems management is more busy with business politics then actually getting engineering done. So this counts as another strike....

I was thinking that was the case. I came to experts-exchange to see if anyone else knew something I didn't.
You've done everything right.
ip igmp lookup-mode ip
vlan <x> ip igmp version3
Can you post the output of the show ip igmp config command, please?
ip igmp lookup-mode ip
vlan <x> ip igmp version3
Can you post the output of the show ip igmp config command, please?

ICMP V3 mode? IGMP is on or off.... IGMP is for multicast management. When a device inquires about multicast then the switch will forward IP multicast packets also to that port (actually IGMP Snooping). if IGMP (snooping) is disabled then all multicast packets are sent to all ports.
