Multi chassis lag speed issues

[CSI_ROMA]

Hi all,
I think I have a problem with a multi chassis lag created on a pair of 8100 in vsx mode.
Let me explain: 

I have a pair of 8100s connected in vsx that I want to connect to an HPE 7503

I create my lag on 8100:

vsxa:
interface lag 100 multi-chassis
description ssfc-irf-lag
no shutdown
no routing
vlan trunk native 1
vlan trunk allowed all
lacp mode active
interface 1/1/1
description ssfc-irf-lag
no shutdown
mtu 9100
lag 100
vsx b:
interface lag 100 multi-chassis
description ssfc-irf-lag
no shutdown
no routing
vlan trunk native 1
vlan trunk allowed all
lacp mode active
interface 1/1/1
description ssfc-irf-lag
no shutdown
mtu 9100
lag 100
hpe 7500:
interface Bridge-Aggregation200
description vsx
port link-type trunk
port trunk permit vlan all
link-aggregation mode dynamic
dhcp snooping trust
interface Ten-GigabitEthernet1/0/0/5
port link-mode bridge
description vsx
port link-type trunk
port trunk permit vlan all
port link-aggregation group 200
interface Ten-GigabitEthernet1/1/0/5
port link-mode bridge
description vsx
port link-type trunk
port trunk permit vlan all
port link-aggregation group 200

here's what the various devices see:

Brief information on interfaces in bridge mode:
Link: ADM - administratively down; Stby - standby
Speed: (a) - auto
Duplex: (a)/A - auto; H - half; F - full
Type: A - access; T - trunk; H - hybrid
Interface Link Speed Duplex Type PVID Description
BAGG200 UP 20G(a) F(a) T 1 vsx
vsxA:

lag100 1 trunk -- yes up -- 10000 ssfc-irf-lag
vsxB:
show interface brief
lag100 1 trunk -- yes up -- 10000 ssfc-irf-lag

is everything normal? I'm a bit confused.

tnx

Pietro
