MSTP issue with Cisco switch

Good morning everybody, After months of passive reading, the time has come for my first forum post. Hope this is the right section for this topic. To simplify my topology, I have an F5 3600 ...

Yes the truth is all the cables are in use: we are testing many different combinations.

Currently, ports 1.5 and 1.7 on both F5's are connected to physical switch n.1, while ports 1.6 and 1.8 to switch n.2.

The unused interfaces are disabled/shutdown.

Cisco interface configuration:


interface GigabitEthernet1/0/1
description to F5-1:1.5
switchport trunk allowed vlan 600
switchport mode trunk
switchport nonegotiate
power inline never
speed 1000
duplex full
spanning-tree link-type point-to-point
end
!
interface GigabitEthernet2/0/2
  description to F5-2:1.6
  switchport trunk allowed vlan 600
 switchport mode trunk
 switchport nonegotiate
 power inline never
 speed 1000
 duplex full
 spanning-tree link-type point-to-point
end
!
!
interface GigabitEthernet1/0/7
 description "to F5-1:1.7"
 switchport trunk allowed vlan 603
 switchport mode trunk
 switchport nonegotiate
 power inline never
  speed 1000
 duplex full
 spanning-tree link-type point-to-point
end
!
interface GigabitEthernet2/0/8
 description "to F5-2:1.8"
 switchport trunk allowed vlan 603
 switchport mode trunk
 switchport nonegotiate
 power inline never
 speed 1000
 duplex full
 spanning-tree link-type point-to-point
end

F5 interface configuration:


root@F5-1(Standby)(tmos) list net interface 1.5
net interface 1.5 {
    mac-address 0:1:d7:be:e5:48
    media-active 1000T-FD
    media-max 1000T-FD
    stp-edge-port false
    stp-link-type p2p
}
 root@F5-2(Standby)(tmos) list net interface 1.6
net interface 1.6 {
    mac-address 0:1:d7:d4:77:89
    media-active 1000T-FD
    media-max 1000T-FD
    stp-edge-port false
    stp-link-type p2p
}


root@F5-1(Standby)(tmos) list net interface 1.7
net interface 1.7 {
    mac-address 0:1:d7:be:e5:4a
    media-active 1000T-FD
    media-max 1000T-FD
    stp-edge-port false
    stp-link-type p2p
}

root@F5-2(Standby)(tmos) list net interface 1.8
net interface 1.8 {
    mac-address 0:1:d7:d4:77:8b
    media-active 1000T-FD
    media-max 1000T-FD
    stp-edge-port false
    stp-link-type p2p
}
