hi,
is this an alias IP/DNS that you SSH to the 9300?
can you post the portion of the 9300 config that you'd like to change/remove?

the Interface Vlan0 IP Address was 192.168.0.1 and it was conflicting with an Industrial Device (PLC) which is taking the same IP address, and it was resolved as follows :
- Show Ip interface brief ( Vlan0 was 192.168.0.1)
- Config t
- Interface Vlan 0
- No Ip address
- exit
-Write memory
Appreciated

The change that you show certainly resolves the issue of duplicated IP address. I do wonder what that IP address for vlan 0 was doing? And whether removing the address impacts anything? Was there anything in the config that refers to vlan 0 or refers to 192.168.0?

when i start up the 9300 , i found the VLAN 0 taking this IP Address (192.168.0.1) and PLC( Other device) is online as i can't change the ip address, as you said yes there is duplicated IP Address, and this Ip Address was for SSH WebUI so i have removed it and now it works fine, i can take the data now from the PLC now
even i switch off the switch in order to confirm that the configuration still there and yes it works fine

hi,
do you have a DHCP server handing out 192.168.0.x/24?
make sure there's static or reserved IP assigned for your LAN devices to avoid any IP conflict.
