OPTICAL SYSTEMS DESIGN
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.
Switch# configure terminal
Switch(config)# interface vlan 1
Switch(config-if-vlan)# ip address 192.168.0.99 255.255.0.0
Switch(config-if-vlan)# end
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)
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
