SET VLAN 1 IP ADDRESS
To display current IP address and subnet mask details;
# show ip interface brief
To configure a new IP address the unit needs to be first set to configuration mode then enter the
interface vlan number, then a chosen ip address. An ‘exit’ from configuration mode is also required
when changes are made. Note that the chosen input arguments (IP address/Subnet mask) are not in bold
shown in the example below.
# configure terminal
(config)# interface vlan 1
(config-if-vlan)# ip address dhcp fallback
192.168.0.99 255.255.0.0
(config-if-vlan)# exit
Note: IP addresses can only be assigned to VLAN interfaces.
After configuration the IP address is completed, the newly allocated IP address can be checked again
by typing in;
# show ip interface brief
If the DHCP negotiation failed, the fallback IP is assigned (192.168.0.99)
DISPLAY AND SAVE CONFIGURATION TO FLASH
It is necessary to save any changes to FLASH storage in the ‘startup-config’ otherwise the changes will
not take effect when the unit is powered off. To save the changes the configuration needs to be copied
to the startup configuration.
# copy running-config startup-config
