IPX

Encapsulation

Types

Novell NetWare

supports four types of frame encapsulation. The

ExtremeWare term for each type is described in Table 11-1.

To configure a VLAN to use a particular encapsulation type, use the
following command:

config vlan xnetid [enet_ii |
enet_8023 | enet_8022 | enet_snap]

Populating the

Routing Table

The switch builds and maintains an IPX routing table. As in the case
of IP, the table is populated using dynamic and static entries.

Dynamic Routes. Dynamic routes are typically learned by way of
IPX/RIP. Routers that use IPX/RIP exchange information in their
routing tables in the form of advertisements. Using dynamic routes,
the routing table contains only networks that are reachable.

Dynamic routes are aged out of the table when an update for the
network is not received for a period of time, as determined by the
routing protocol.

Static Routes. Static routes are manually entered into the routing
table. Static routes are used to reach networks not advertised by
routers. You can configure up to 64 static IPX routes on the switch.
Static routes are never aged out of the routing table. Static routes are
advertised to the network using IPX/RIP.

Name

Description

ENET_II

The frame uses the standard Ethernet 2 header.

ENET_8023

The frame includes the IEEE 802.3 length field, but does not include the IEEE
802.2 Logical Link Control (LLC) header. This encapsulation is used by NetWare
version 2.x and the original 3.x version.

ENET_8022

The frame uses the standard IEEE format and includes the IEEE 802.2 LLC header.
This encapsulation is used by NetWare version 3.12 and 4.x.

ENET_SNAP

The frame adds a Subnetwork Access Protocol (SNAP) header to the IEEE 802.2
LLC header.
