There is no technical concept of access port. It is just naming, and that is where the ArubaOS / HP Procurve/Provision switches just take a different approach:
- Access port: means there is just one VLAN assigned to the port, which does not have a vlan tag (802.1q); optionally there is a voice VLAN that has a tagged vlan.
- Trunk port: means there are multiple VLANs, which have a vlan tag (802.1q); and optionally there can be one 'native VLAN' which then doesn't have a tag.
interface 1/1/1
port access vlan 10
would be: vlan 10 untagged 1/1/1
interface 1/1/1
port trunk allowed vlan 11,12,13,14
port trunk native vlan 10
would be:
vlan 10 untagged 1/1/1
vlan 11 tagged 1/1/1
vlan 12 tagged 1/1/1
vlan 13 tagged 1/1/1
vlan 14 tagged 1/1/1
The difference is that on other switches, the configuration is tied to the interface (add vlans as access/native or trunk allowed), where on ArubaOS switch the configuration is tied to the VLAN (add interfaces in tagged or untagged).
By default, all ports are untagged in VLAN 1; or in the other terminology: access vlan 1.

Thanks heaps Ivan.
Does it mean that these HP switches do not have an access port by default ?
Thanks
Champ

Hi Champion!
Port 22 has VLAN50 and VLAN16 tagged and VLAN12 untagged (native VLAN). VLAN1 has been excluded from the port (disabled).
"As I understand that you can only have one port for access and another for trunk" - port 22 is a typical 'trunk' where one or more VLANs are tagged and one single VLAN is untagged on the port. That untagged VLAN you can consider it as 'native VLAN' (Cisco term) or 'PVID' (industry standard term).

Hi all,
I am new to the HPe old switch OS. Just gpoing through some old config.
Could anyone explain to me why the following vlan is tagged and untagged in the same port (Port 22), to be precise?
As I understand that you can only have one port for access and another for trunk, why has hpe done it this way?
vlan 1
name "DEFAULT_VLAN"
no untagged 1-12,15-20,22-23
untagged 13-14,21,24-28
ip address dhcp-bootp
ipv6 enable
ipv6 address dhcp full
exit
vlan 12
tagged 21-22,24
ip address 10.12.150.254 255.255.255.0
exit
vlan 16
name "Point-Point"
tagged 22,24
vlan 50
untagged 17-20,22
ip address 192.168.12.254 255.255.255.0
ip helper-address 192.168.12.252
ip helper-address 192.168.12.252
exit
