	■	1200	■	112 K
	■	1800	■	128 K
	■	2400	■	256 K
	■	3600	■	384 K

	■	38 K	■	1536 K
	■	56 K	■	1580 K
	■	64 K	■	2048 K

If you conﬁgure a baud rate that is different from those listed, the system will fall back to the nearest lower supported rate.

BGP Conﬁguration Files Prior to software version 10.1, BGP conﬁguration ﬁles were written to ﬂash memory every 10 SETDs, ADDs, or Deletes. Beginning with version 10.1, BGP conﬁgurations are saved to ﬂash memory immediately after each change, which practically eliminates the need for the SAVEbgp command.

3Com recommends that you pay special attention to bridge/router platforms running NETBuilder software version 10.1 and greater with pre-10.1 releases in the same network. Always enter the SAVEbgp command on any bridge/router running software previous to version 10.1 to make sure that all the BGP conﬁgurations are written to ﬂash memory. Failure to do so may result in all the BGP conﬁgurations being lost after the next reboot.

Prior to NETBuilder software version 10.1, all IGP routes except OSPF External routes were imported into the BGP routing table by default. Beginning with NETBuilder software version 10.1, the “import” of IBP routes into BGP is controlled by the BGP IntPolDefault parameter.

BSC Cabling and The data communication equipment (DCE) cable for SuperStack II bridge/routers Clocking should be 07-264-000-01 (rev. 1) to work in BSC internal clocking mode.
