1 The Digi International RightSwitch SE-X (dgrs) Device Driver 2 3This is a Linux driver for the Digi International RightSwitch SE-X 4EISA and PCI boards. These are 4 (EISA) or 6 (PCI) port Ethernet 5switches and a NIC combined into a single board. This driver can 6be compiled into the kernel statically or as a loadable module. 7 8There is also a companion management tool, called "xrightswitch". 9The management tool lets you watch the performance graphically, 10as well as set the SNMP agent IP and IPX addresses, IEEE Spanning 11Tree, and Aging time. These can also be set from the command line 12when the driver is loaded. The driver command line options are: 13 14 debug=NNN Debug printing level 15 dma=0/1 Disable/Enable DMA on PCI card 16 spantree=0/1 Disable/Enable IEEE spanning tree 17 hashexpire=NNN Change address aging time (default 300 seconds) 18 ipaddr=A,B,C,D Set SNMP agent IP address i.e. 199,86,8,221 19 iptrap=A,B,C,D Set SNMP agent IP trap address i.e. 199,86,8,221 20 ipxnet=NNN Set SNMP agent IPX network number 21 nicmode=0/1 Disable/Enable multiple NIC mode 22 23There is also a tool for setting up input and output packet filters 24on each port, called "dgrsfilt". 25 26Both the management tool and the filtering tool are available 27separately from the following FTP site: 28 29 ftp://ftp.dgii.com/drivers/rightswitch/linux/ 30 31When nicmode=1, the board and driver operate as 4 or 6 individual 32NIC ports (eth0...eth5) instead of as a switch. All switching 33functions are disabled. In the future, the board firmware may include 34a routing cache when in this mode. 35 36Copyright 1995-1996 Digi International Inc. 37 38This software may be used and distributed according to the terms 39of the GNU General Public License, incorporated herein by reference. 40 41For information on purchasing a RightSwitch SE-4 or SE-6 42board, please contact Digi's sales department at 1-612-912-3444 43or 1-800-DIGIBRD.
