internally, while all other traffic is bridged. With IP host mode, AppleTALK and/or IPX routing
may also be enabled.
Off-node authentication servers are available when IP is enabled regardless of the operating mode.
With IP host mode, all traffic is considered bridge traffic, so no IP-specific off-node server lookups
are performed. These include:
•
IP lookup by a next hop IP address or a next hop device name
• Route lookup by a destination IP address
When the IP operating mode is changed from one mode to the other, changes are automatically
made to the configuration sensitive to the IP operating mode.
The IP network interfaces in the router mode and the IP network interface in the host mode are
internally stored separately, and therefore they are preserved between the mode switching.
IP static routes are not actually sensitive to the IP operating mode, but they are sensitive to IP
network interfaces. As a result, changing the IP operating mode (i.e., changing the network
interface configuration) may result in invalidating some of the static routes. Be sure to check this.
Correct invalid static routes before restarting the system to avoid the deletion of these routes.

Note: IP RIP v1 refers to IP RIP Version 1, and IP RIP v2 refers to IP RIP Version 2. IP RIP v1
supports broadcasting, and IP RIP v2 supports multicasting. The CyberSWITCH supports
either version. If you are using IP RIP, you need to know what version of IP RIP the other
devices using the IP RIP LAN interface supports.
1. Configure all required IP interfaces. If you previously configured the IP operating mode as
routing, the interfaces described in steps 2 through 6 are available. If you previously configured
the IP operating mode as host, only one interface will be available. That interface type is
described in step 7. To begin, select IP Interfaces from the IP configuration menu. Select Add.
2. For a LAN IP network interface enter the following information. (Note: you may add more than
one LAN IP network interface.)
a.
interface name
b. IP address assigned to this interface
c. subnet mask
d. LAN port number
e.
packet encapsulation type
f. MTU size
g. enable/disable Proxy ARP feature
h. transmit broadcast address
i.
input/output filter name
If IP RIP is enabled, enter the following additional information:
j. IP RIP send control
k. IP RIP respond control
