Yeah. I did that:
(S4A)(su)->sh port stat tg.2.8
Port Alias Oper Admin Speed Duplex Type
(truncated) Status Status (bps)
------------ ---------------- -------- ------- ------ ------- ------------------
tg.2.8 up up 10.0G full 10g-sr lc
1 of 1 ports displayed, 1 port(s) with oper status 'up' or 'dormant'.
(S4A)(su)->sh port jumbo tg.2.8
Port Number Jumbo Oper Status Jumbo Admin Status Jumbo MTU
----------- ----------------- ------------------ ---------
tg.2.8 Enabled Enabled 10239
(S4A)(su)->sh mtu
MTU disovery status: Enabled
(S4A)(su)->sh int vlan.0.1528
vlan.0.1528 is Operationally up, Administratively up
MAC-Address is: 00-1f-45-5c-4d-ec
The name of this device is vlan.0.1528
ARP/ND cache limit is 65535
MTU is 1500 bytes <--------------------Not sure how to change this:
Encapsulation ARPA, Loopback not set
IP Policy Routing disabled
(S4A)(su)->set port jumbo enable vlan.0.1528
vlan.0.1528 does not support specified feature.

you need to use
set port jumbo enable <port-string>
and show port jumbo
Here's is my listing from an S4:

Hello Jay,
we do nat have experience with S-series, but I'll try to guve my three cents...
There ist a command "set mtu {enable | disable}":
Enables or disables path MTU discovery protocol.
Did you try "set mtu enable" (should be enabled by default)?
Did you set all ports, which are belonging to this vlan, to jumbo? Or are some
l2 ports belonging to this vlan left with default mtu?
Which mtu do you see on issueing a "show interface" command?
Kind regards
Reinhard
