Frame Types

Introduction

To support a broad base of network stations, the access server supports four different frame formats for encapsulating IPX packets on the LAN. The four frame types supported by the access server can be enabled simultaneously:

∙Ethernet

∙RAW802

∙SAP802

∙SNAP802

A LAN frame is enabled when a unique NetWare network number is associated with the frame. The network number can be automatically “learned” or explicitly configured. By default, all four frame types attempt to learn their network number by monitoring frames on the network.

Standard Ethernet

This packet format is the standard Ethernet V2 packet format (protocol type 8137).

RAW802

This mode uses IEEE 802.3 format frames without an IEEE 802.2 LLC header. This mode is often called “raw” 802.3.

SAP802

This mode encapsulates IPX frames using IEEE 802.2 LLC standard header formats. The SSAP and DSAP for IPX is E0.

SNAP802

This mode uses the IEEE 802.2 LLC format with the SNAP SAP format. The SNAP protocol ID for IPX is 00-00-00-81-37.
