Chapter 3 - IPX Routing & Bridging
Ethernet Type II is commonly used by TCP/IP and DECnet. The default 
seeding value is Non-Seed.
Ethernet 802.3 (Raw) is the default frame type for earlier versions of 
Novell Netware. The default seeding value is Auto-Seed.
Ethernet 802.2 is a modified version of Ethernet_II and is the default 
frame type for Novell Netware 4. The default seeding value is 
Auto-Seed.
Ethernet 802.2 SNAP is used by the AppleTalk protocol. The default 
seeding value is Non-Seed.

IPX Routing/Bridging/Off
This set of radio buttons controls how IPX packets are handled for this inter-
face.
If set to IPX Routing, then IPX packets received on this interface are 
routed to the correct interface on the device.
If set to IPX Bridging, then any IPX packets received on this interface 
are forwarded to the device’s internal bridge. This setting makes this 
Ethernet interface a member of the “IPX Bridge Group” for this device.
v Note:  The IPX Bridging radio button will be grayed out unless bridging 
has been turned on globally for the device using the Main Bridging Configu-
ration Dialog Box (under Global/Bridging) and locally on this interface 
using the Ethernet-Bridging Dialog Box (under Ethernet/Bridging). 
If it is set to IPX Off, then any IPX packets received on this interface are 
discarded.

Seed Status (per Frame Type)
One of the functions which routers perform in IPX internetworking is setting 
the IPX network number for each network segment. A router which sets the 
network number for a segment is said to have “seeded” the network.
Seed means the device will listen for an IPX network number being set 
by another router (including Novell software routers residing on servers) 
on the segment connected to this interface and use this number if it exists. 
If it doesn’t discover a number in use, the device will use the configured 
IPX Network Number (discussed below) to set the network number for 
the segment.
Non-Seed means the device will listen for an IPX network number being 
set by another router (including Novell software routers residing on 
servers) on the segment connected to this interface and use this number
