3Com 11.1 Sdlc Adjacent Link, Stations for Appn, Source Route, Transparent Bridging, Gateway Srtg

48NETBUILDER SOFTWARE VERSION 11.1 RELEASE NOTES

■SDLC end-to-end through local switching (conversion to a single LLC2 LAN connection between two NETBuilder bridge/routers) requires different virtual ring numbers in the LLC2 Service.

SDLC Adjacent Link	When you configure SDLC adjacent link stations for APPN, if an active link
Stations for APPN	becomes inactive and you change the port definition using the PortDef parameter,
	the link remains inactive. If you try to reactivate the link using the SET -APPN
	LinkStaCONTrol command, the link reactivates within 30 seconds. To activate the
	link immediately, you must enable the APPN port using the SET -APPN PortControl
	= Enable command.
Source Route	The NETBuilder II bridge/router cannot interoperate with Cisco or IBM routers if
Transparent Bridging	the NETBuilder bridge/router is configured using Source Route Transparent
Gateway (SRTG)	Gateway (SRTG) with Source Route bridging on the token ring LAN port and
Interoperability	Transparent Bridging on the PPP or Frame Relay WAN ports. In this configuration,
	the NETBuilder II bridge/router is sending using PPP bridge encapsulation 802.5
	token ring format, while the IBM 6611 and the Cisco 400 router are using PPP
	bridge encapsulation 802.3 Ethernet format.
SDLC Ports and NetView	An SDLC port defined for NetView Service Point cannot be used for SDLC-to-LLC2.
Service Point
Source-Route	The source-route transparent gateway is not currently supported on ATM LAN
Transparent Gateway	emulation ports.
Token Ring+ Modules	The maximum physical frame size that can be forwarded by the Token Ring+
	modules with NETBuilder bridge/router software is 4,500 bytes. This software
	limitation affects routing, source route bridging, and transparent bridging.
	Token Ring Auto Start-up
	The Token Ring and Token Ring+ modules may enter the ring at the wrong speed
	with certain MAU or station configurations. You can manually configure the -PATH
	BAud value to 16,000 or 4,000 to avoid this situation.
VRRP Configuration	VRRP cannot coexist with DECnet, LAA, OSI, or IPv6.
