    Cisco Switch
    - vlan 1 "management" - ip address 192.168.1.254 255.255.255.0
    - vlan 2 "students"
    - vlan 3 "staff"
    - default gateway 192.168.1.1
    - int fa 0/1 - switchport mode access - switchport access vlan 1
    - int fa 0/2 - switchport mode access - switchport access vlan 2 
    - int fa 0/3 - switchport mode access - switchport access vlan 3 (Device 2)
    - int fa 0/23 - switchport mode trunk - switchport trunk allowed vlan all - switchport trunk native vlan 1 (Aruba Switch to ge 0/0/23)
    - int fa 0/24 - switchport mode trunk - switchport trunk allowed vlan all - switchport trunk native vlan 1 (Cisco Router)

     

    Cisco Router
    - vlan 1 "management"
    - vlan 2 "students"
    - vlan 3 "staff"
    - int fa 0/0 - no shutdown
    - int fa 0/0.1 - ip address 192.168.1.1 255.255.255.0 - Encapsulation Dot1q 1 native
    - int fa 0/0.2 - ip address 192.168.2.1 255.255.255.0 - Encapsulation Dot1q 2
    - int fa 0/0.3 - ip address 192.168.3.1 255.255.255.0 - Encapsulation Dot1q 3

     

    Aruba Switch
    - vlan 1 "management" - ip address 192.168.1.253 255.255.255.0
    - vlan 2 "students"
    - vlan 3 "staff"
    - ip default-gateway 192.168.1.1
    - int ge 0/0/0 - switchport mode access - switchport access vlan 1
    - int ge 0/0/1 - switchport mode access - switchport access vlan 2 (Device 1)
    - int ge 0/0/2 - switchport mode access - switchport access vlan 3
    - int ge 0/0/23 - switchport mode trunk - switchport trunk allowed vlan all - switchport trunk native vlan 1 (Cisco Switch to fa 0/23)


    Device 1 is on VLAN 2 (192.168.2.25) - plugged into Aruba switch (port ge 0/0/1)
    Device 2 is on VLAN 3 (192.168.3.25) - plugged into Cisco switch (port fa 0/3)

     

    Pings:
    - from device 1 I cannot ping device 2 or Aruba switch
    - from device 1 I can ping all three router interfaces and cisco switch
    - from device 2 I cannot ping device 1 or Aruba switch
    - from deviec 2 I can ping all three router interfaces and cisco switch


    Not sure why I can't ping from device 1 to device 2, device 2 to device 1 or from either device to Aruba switch?

    Are your ports trusted on the Aruba side?

    Yes ports are trusted, device 1 is directly connected to Aruba switch with access vlan 2 (device ip 192.168.2.25) and I cannot ping the device from the switch. I can ping the gateways and cisco switch however from the Aruba. 

     

    Aruba switch is in vlan 1 (192.168.1.253)

    Try checking the show spanning-tree summary and see if theres anything blocked on the Cisco side of things

    Checked spanning-tree and nothing is being blocked on the Cisco devices or on the Aruba.

    Can you do a show IP route on both sides
