This example first sets up a dedicated VLAN for management access. It
adds Port 19 (the management port) to that VLAN and also removes this
port from the VLAN 1, which is left for use by the data network. It then
specifies the management interface, IP address and default gateway. For
information on making these configuration changes throu gh the web
interface, refer to Chapter 13 “VLAN Configuration.”
Renewing DCHP – DHCP may lease addresses to clients indefinitely or
for a specific period of time. If the address expires or the stack is moved to
another network segment, you will lose management access to the stack. In
this case, you can reboot the stack or submit a client request to restart
DHCP service via the CLI.
Web – If the address assigned by DHCP is no longer functioning, you will
not be able to renew the IP settings via the web interface. You can only
restart DHCP service via the web interface if the current address is still
available.
CLI – Enter the following command to restart DHCP service.
