After reboot of the icx 7750 device following and outage the device is not responding to ARP request

Question

So I had a network outage due to a Domain controller crashing during the troubelshooting for this I rebooted my ICX7750 which acts as our core switch and router. after fixing the DC issue our network came back up on our ethernet Vlan but our other vlans are sending out ARP request looking for their defalt gateways on the switch but are not being responded to. the gateways are all responding to pings from the ethernet network. I loaded a back up of the config from about one week befor the outage but their was no improvment. I can't work out why the switch would not be responding to the ARP messages?

Hi Jdziech

Ack and Noted. Thanks for sharing the details.

Since you are also running a older version 8060 I also suggest you to take a maintenance to plan a upgrade on the device, since the current version you are running is old.

However as you are running a very old code there has been a lot of changes with commands on the latest version.

I would suggest you to log a case with us and discuss about the issues encountered and take a call to upgrade if not a configuration issue.

Hi Chandini,
For clarity the working ethernet VLAN is 2020 the VLAN we are having issues with is 2032 and it's IP address on the switch is the default gateway for the 2032 VLAN devices on the 2032 VLAN cannot find the 2032 gateway but ones on 2020 can.
the switch can ping the default gateway and it can be ping by end devices on the working ethernet VLAN 2020 but cannot from endpoints on VLAN 2032. traceroute on the switch will show that the address is local. traceroutes from devices on the 2020 VLAN will resolve after 2 to 3 hops depending on how their wired in to the network (these paths are correct) but devices on VLAN 2032 will show destination host unreachable Pings will also not resolve. I have tested the physical connection to the 2032 VLAN and there is not an issue. We are licensed for L3 routing on this device and L2 is also enabled. I have also configured other used ports to take the place of the ports in LAG 2 where VLAN 2032 comes in to the network but this resulted in no change. show version and traceroute from the switch bellow. Thanks

Hi Team

Ack and Noted. Could you please let me know if you are able to ping the default gateway from the switch and from the end device ?

Is the switch code a router code or a switch code ? Could you share output of "show version " ?

Could you also try to traceroute from end device and see if the traceroute 1st hop points to default gateway on vlan 2032 or not ?

Thanks
