Switch Module IP Addresses
IP addresses can be assigned to two of the switch module interfaces:
• The Fa0 Ethernet interface. This Layer 3 Ethernet interface is connected to the Onboard
Administrator through which you can manage the switch module. It is used only for switch module
management traffic, not for data traffic.
• The VLAN 1 interface. You can manage the switch module from any of its external ports through
VLAN 1.
When you install the switch module, you need to determine whether the Onboard Administrator is
connected to a network in which a DHCP server is also connected or if the Onboard Administrator has
been configured as a DHCP server. If either of these conditions is true, the switch module automatically
obtains an IP address for its Fa0 Ethernet interface that is connected to the Onboard Administrator. In
this case, a VLAN 1 IP address is not assigned, and to set up the switch module by using the Device
Manager you must use the Fa0 interface IP
address that the DHCP server assigns.
See the “Using the Onboard Administrator to Assign an IP Address to the Switch Module and Running
Express Setup” section on page 2-9 for procedures on setting up the switch module if the IP address is
being assigned dynamically.
