hi! I've a switch (2950) with flat network with no configration at the ports. If i would to change the default vlan 1 ip address to a new network ip and default gw(different network segment from the existing one), because we are relocating the switch. Will it impact the user connected to the switch? or it will just diable me to connect to the switch through ip? I just want to confirm that it will not impact the existing user. I would like to change the mgt lan ip before we move the switch. Thx.
Layer 2 switches don't use IP-addresses to communicate on the LAN, it uses MAC-addresses. So changing an IP-address on a switch will not disrupt anything.
Assuming that VLAN 1 (the layer 2 VLAN and not the VLAN interface for layer 3) remains the same then users connected to the switch will not be impacted if you change the IP address of the management interface of the switch on interface vlan 1. The IP address on the switch is used only for management traffic to and from the switch. Changing the management IP address has no impact on user traffic being forwarded at layer 2 by the swtich.
