Excess Sap Traffic on 4.11

By collins_ms ·
I'm running netware 4.11 intranetware SBE with groupwise 5.2 and novell 3.21 clients. We also have a snap server with bindery emulation. Over the last month, using an analyzer alot of sap traffic (802.2) is being generated between devices. Network traffic has been well over 40%or higher FOR EXTENDED PERIODS OF TIME. I don't believe that I need to run the 802.2 frame type in 4.11. Can I trun off this frame type?

Assuming you are running TCP/IP. It's been a while but as I recall you can configure a SAP filter using ICONFIG. The clients will 'see' the list of services available when they login and won't need to listen for the SAP broadcasts.

Assuming all your clients are set up to use 802.3 yes you can turn it off. I would do this at night or on the weekend so you can make sure all your servers can talk to each other and I would check at least a few workstations for functionality.

If you are using both IPX and IP, then you can run these both over Ethernet_ii. You may want to visit client P.C's and optimise/alter them to the ethernet_ii frame type. Also, you can check INETCFG for the method the servers are using to pass route information to each other. Make sure that they are trying to use "NLSP with RIP/SAP compatibility" instead of just RIP/SAP.
Also check any Network Printer devices on the network, ans the frame types being used. They generally default to just about all frame types out of the box. This can become a serious problem in networks with lots of them.

Since you are running 4.11 SBE, that tells us that your LAN has 50 or fewer devices and is running IPX/SPX. You mentioned that you used a protocol analyzer to generate a report on your LAN and discovered that you have over 40% network traffic.
I have a couple of questions for you though. Are your Win9x PC configured with File & Printer sharing enabled? If so, turn that off. Make sure the client PC's are only using IPX/SPX and possibly TCP/IP, no NetBEUI.
As to frame type; in a 4.x IPX only environment, you want to use 802.2 and not 802.3. Does your snap server support 802.2? If so, use that frame type instead of 802.3. In a mixed protocol enviroment, you can run both TCP/IP and IPX/SPX on the Ethernet II frame type. Be aware theIPX communications using that frame type can be slower. And check your JetDirects. Configure them for the IPX frame type that you have standardized on and only that frame type. Turn off unneccessary protocols.
Summary

You can load IPXCON.NLM on the server to view what SAP's the server see's. From this list you can determine where the sap's are coming from, consult a list of sap numbers from the web to better understand the numbers. If your running IPX you will need either frame type 802.2 or 802.3 but you do not need both unless the client devices are a mix of both frame types.
