Hi

new user to Aruba devices, i have a topology of two  JL635A  8325-48Y8C  GL.10.13.1090 as my DataCenter WAN switches.

i have an ISP connection from my provider as a single-Mode PatchPanel in my Rack

i have connected that port to port 1/1/18 with Aruba SFP LR 1G:

interface 1/1/18-1/1/20
    description Backup ISP-Uplink-1G
    no shutdown
    no routing
    vlan access 20
    exit

vlan 20
    name Secondary-ISP_1G
interface vlan 20
    name Secondary-ISP_1G

then i connected my two HA FortiGate to port 1/1/19 and 1/1/20 for primary and backup.

i have MACs from FortiGate side but not from ISP side 1/1/18
tried to connect directly to the FortiGate and it worked
also this topology currently exist in DELL switches which I'm trying to replace 

Interface 1/1/18 is up
 Admin state is up
 Link state: up for 31 minutes (since Sun Nov 30 09:43:15 UTC 2025)

Hello, was the Interface Group 2 (a group of twelve physical SFP28 ports - supporting 1G, 10G, 25G connection speeds - from interface 1/1/13 to interface 1/1/24) of your HPE Aruba Networking CX 8325‑48Y8C 48‑port 25G SFP/SFP+/SFP28 and 8‑port 100G QSFP+/QSFP28 Switch configured for the 10G speed (which also supports 1G speed)?

If you have already fixed that part try adding:

speed 1000-full

into the interface 1/1/18 context.

In any case it would be of help if you report sanitized outputs of these commands:

show interface brief
show system interface-group
show interface 1/1/18
show interface 1/1/18 transceiver detail
