Inter VLAN Routing Aruba 2920

My company bought a new Aruba 2920-48G switch which is intended for creating 3 new vlans. The plan is to use the switch to route the traffic of the new VLANs. As a test, I created two VLANs and tried to communicate them using "ip routing" command, but I failed.

This is my switch configuration:

Running configuration:

; J9729A Configuration Editor; Created on release #WB.16.02.0012
; Ver

hostname "HP-2920-48G-POEP"
module 1 type j9729a
ip routing
snmp-server community "public" unrestricted
   ip address dhcp-bootp
vlan 1
   name "DEFAULT_VLAN"
   no untagged 1-8,13-20
   untagged 9-12,21-48
   no ip address
vlan 10
   name "VLAN10"
   untagged 1-8
   tagged 9-12,21
   ip address
vlan 20
   name "VLAN20"
   untagged 13-20
   tagged 21-24
   ip address


And these are my test hosts' configuration:

Hosts Info:
First Host. Plugged in a VLAN 10 port

IPV4 Address:
Subnet Mask:
Default Gateway:

Second Host. Plugged in a VLAN 20 port

IPV4 Address:
Subnet Mask:
Default Gateway:


Pinging any host would result on either a timeout for an untagged port or a destination host unreachable for a tagged port. However, a "show arp" command on the switch shows both hosts, so I thinkthe problem is that I am missing something in the switch configuration.


Please keep in mind that I am completely new to Aruba switches, so any help would be appreciated.

Re: Inter VLAN Routing Aruba 2920

It is fixed now. The problem was that Windows Firewall was blocking the packets. This is fine because the new VLANs are intended for PLCs and DVRs.
