Hi,

Can you check after removing these pvid from  Port GE1/0/1 |H3C S8500 | ?

undo  port trunk pvid vlan 100

If this will not work then I need some time to check into LAB because other side is Aruba.

Thanks!

Hi,

this is one of the things I crosschecked already twice.

It did not help either.

The only thing I have changed on aruba 7005 side was switching GE0/0/3 from access into trunk mode.

With the 2910 "access mode" was the working way. With 5800 neither "access" nor "trunk" makes any difference.

If there is an alternative way on aruba 7005 to forbid the subnet where the 5800 itself is in BUT to only allow the default gateway which is of course in the same subnet - I could live with a solution like this, too. (I know how to set rules on aruba for subnet denial but don´t know how to allow one single host in that very same subnet)

Hi,

I have tested this into LAB and it was working fine for me.

Other side I kept another device of Aruba and kept only below config:

Aruba Side:

interface gigabitethernet 0/0/3

    description "GE0/0/3"

    trusted

    trusted vlan 100

    no poe

    switchport mode trunk

    switchport access vlan 100

    switchport trunk allowed vlan 100

HPE 5800 Side:

interface GigabitEthernet1/0/1
port link-mode bridge
port link-type trunk
undo port trunk permit vlan 1
port trunk permit vlan 100

Kindly make changes like this and check and if won't work then please log a case with support.

Thanks!
