40NETBUILDER SOFTWARE VERSION 11.1 RELEASE NOTES

NETBuilder II port at the central site. An alternative work around is to conﬁgure APPN with DLSw at the central site and to use the CEC’s MAC address at the remote site.

APPN CP-CP Sessions on When parallel transmission groups (TGs) are conﬁgured between 3Com network Parallel TGs nodes and both TGs support CP-CP sessions, a CP-CP session on one TG does not switch to the other TG if the user disables the port or path. This happens because

both sides learn about the link failure at different times. The network node with the disabled port or path learns about the link failure right away and tries to bring CP-CP sessions up on the second TG. However, the second network node does not learn about the link failure until LLC2 times out; because it thinks the link is still up, the second network node does not allow CP-CP sessions to start on the second TG. After ﬁve attempts at bringing up CP-CP sessions on the second TG, the second TG will be ﬂagged as not supporting CP-CP sessions, preventing CP-CP sessions from coming up on that second TG. To prevent this situation, manually stop the ﬁrst TG by entering the SET -APPN LinkStaCONTrol <LinkName> Deactivate command before disabling the port/path. By doing this, both network nodes will learn that the link has gone down at the same time, and CP-CP session can be activated on the second TG.

ATM Connection Table In a LAN Emulation environment with many LAN Emulation Servers (LESs), a performance drop may occur when the NETBuilder bridge/router is able to connect to the LAN Emulation Conﬁguration Server (LECS), but many of the LESs are down or unreachable. Disabling the ETHATM virtual ports corresponding to the unreachable LESs will alleviate this situation.

Baud Rates for Although the maximum asynch speed supported by NETBuilder software version Async PPP 11.1 is 38.4 bps, no error message is reported if the BAud parameter in the -PATH

Service is conﬁgured to a larger value. A higher baud rate will be accepted and displayed, but the path will actually operate at 38.4 bps.

BGP MaxPeers When changing the value of the BGP Service MaxPeers parameter, make sure that Parameter Changes BGP control is disabled and all peers are in the idle state before attempting to set the MaxPeers value. There is a period of time after BGP control has been disabled

when the peers are ﬂushing the routes in preparation for entering the idle state. Attempting to change the value of MaxPeers before the peers have entered the idle state may cause the router to crash.

Boot Cycle If the OfﬁceConnect bridge/router fails to complete the boot cycle and enters a Continuous Loop boot cycle loop (for example, if the boot image is corrupted), press the ESC key to

interrupt the boot cycle and enter monitor mode.

Change Conﬁguration The options on the Change Conﬁguration and Diagnostic menu do not apply to and Diagnostic Menu the model 1x1 OfﬁceConnect bridge/router because ISDN ports are not present on

this system.

Changing the Transfer The PATH service parameter TransferMode should not be changed from its default Mode Parameter Default value of AUto. Other settings of this parameter are reserved for future extensions.

CHAP Rejection Message When using only the SysCallerID to map calls on a dynamic path to a virtual port, you may see the following message just before the path comes up:

WARNING: CHAP on Port !<port> rejected; No AuthLocalUser configured!
