Dear all,
I hope someone can help. I did a mistake and managed to set #ip arp inspection vlan 1 - and that’s the only vlan on the switch. I did not do DHCP snooping first. I got locked out from the Telnet session and cannot get back in. Now I'm locked out of the switch and can't connect via Telnet. Probably because my MAC address is denied? On top of this it seems the switch saved running config automatically, so a switch reset did not work.
How do I access a CLI for the switch or somehow reverse the mistake?
I am so thankful for any help!

You might need to connect to the console session on the device. Feel for you

Switch(config-if)# no ip arp inspection trust

Thank you for your answer. I can't get into the switch to do the configuration. Seems like I'm being denied when I try to access the switch's CLI. It is also a DHCP environment.

Of course I meant that i wish to reset my fault with the #no ip arp inspection vlan 1 command
