Linus Torvalds1da177e2005-04-16 15:20:36 -07001 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.
