Try to set the jumbo statement to all VLANs associated to those ports.
Example:
vlan 1
name "DEFAULT_VLAN"
no untagged 1-6,8-9
untagged 7,10
no ip address
jumbo
exit
vlan 2
name "Home_Wired"
untagged 8-9
no ip address
jumbo
exit
sw00# show vlans
Status and Counters - VLAN Information
Maximum VLANs to support : 256
Primary VLAN : DEFAULT_VLAN
Management VLAN : Management
VLAN ID Name | Status Voice Jumbo
------- -------------------------------- + ---------- ----- -----
1 DEFAULT_VLAN | Port-based No Yes
2 Home_Wired | Port-based No Yes

you can't set MTU on AP that run AOS10 as they'll dynamically learn it . So it will be on switch and gateway

If my post was useful accept solution and/or give kudos.

Hi all.
I have an Aruba Central version 10.x solution (Yes version 10 so Cloud Managed devices, no instant)
with SSID tunnelling traffic from APs (AP-5xx so 11ax) and the GW.
The wired network is not Central managed
How should I set the MTU ?
Should I set the MTU on APs and GW or on the switches ?

Unless you are tunneling traffic from an access point to a controller, this thread doesn't apply to Central-Based Instant access points.

Hi.
I cannot find any MTU settings in Aruba central? (Checked under Access point (tab) -> config -> System (tab) and wish "show advanced").
Could you please provide a screenshot or a more exact description of where/how this setting is accessed/modified?
(funny thing is I'm 99.9% sure I've seen MTU during setups lots of times so I'm wondering if it's been removed in newer versions of central)

That link was before the forum was migrated. The tl;dr is to set the MTU in the AP system profile to 1500 to stop the "giants".

Colin,
I cannot access some of the articles linked from above. Is this a problem or just an annoyance? If nothing is broken, should I be concerned?
Thanks,
Jim

This is a little dated. Is this still relevant with 8.x code? I am seeing the same thing here on an HPE/Aruba switch with an Aruba AP attached to it.

Yes, if you set the AP MTU to 1500, it should solve the problem.
Thanks,
