You have to be root user in order to add a new user Operation To simply the operation all functions are provided in a single command called osctl osctl provides 3 major functions 1 Network amp Host configuration allowed only in root 2 Switch Control amp Status 3 Port group Management Network amp Host configuration The following are the commands used to configure network 1 To configure static IP osctl i lt ip gt m lt mask gt g lt gw gt 2 To use DHCP dynamic IP osctl D 3 To configure hostname alone osctl h lt hostname gt 4 Toconfigure aDNS or Nameserver you can use n option of osctl osctl n lt dns_server_ip gt 5 To configure syslog server to receive FC811 s events osctl S lt syslog_server_ip gt For details refer to installation section as these are explained in that section In order to switch ON or OFF particular a port or ports or a group you can use following command S osctl p lt port s gt lt port_range gt lt port_group gt lt on off gt t lt secs gt Note that the braces groups options and is equivalent to or If the options are in square brackets then it is optional Wherever you see port or in_port they all the same and represents one of 8 ports of FC811 For example osctl p 4 on gt switch port 4 to ON LED on port 4 of FC811 lids when this command is issued which confirms that th

6. ay amp DNS as 192 168 1 Once the IP is configured from a PC or a Laptop using Ethernet or serial port you can then connect FC811 to your network and access it using telnet or ssh Configuring Dynamic IP If you have a DHCP server running on your network and you may want to dynamically assign an available IP address to FC811 by using following option osctl D Make sure you know the assigned IP address to login using telnet or ssh Configuring Hostname You can also change the hostname of FC811 switch using osctl osctl h FC811 SW 1 The above command changes hostname of FC811 to FC811 SW 1 Configuring DNS Nameserver To configure a DNS or Nameserver you can use n option of osctl osctl n 192 168 1 11 Configuring Syslog Server m To send system generated events to an external syslog server use S option of osctl You have to specify the address of the syslog server which will receive these event logs Note this option only available in software version 2 0 and above osctl S 192 168 1 200 Version Info The following command shows hardware and software versions and serial number of the switch osctl v Other Administrative commands Most of other administrative functions can be done using standard Linux commands For example to change the password use passwd command from the Linux prompt and to add new user use useradd command
7. c option as explained in Group Management section S osctl s 2 gt shows port 2 status only Port group Management Port group management commands provide convenience of switching bunch of ports together identified by a name Group name can be any alpha numeric name Group name can not be just a number or start with a number For example group name can not be 10 or 10gp1 1 To create a new group S osctl c lt port_group gt lt in_portH s gt lt inport_range gt 2 To update existing group S osctl u lt port_group gt a r lt in_port s gt 3 To delete a group S osctl d lt port_group gt 4 To delete all groups S osctl R 5 To list ports in a group S osctl I lt port_group gt lt in_port gt For example S osctl c gp1 13 4 gt creates group named gp1 with ports 1 3 and 4 The double quotes around space separated port numbers are required Note that when you create a group all the ports in the gp1 will be in OFF state by default S osctl c gp2 5 8 gt creates group named gp2 with ports 5 6 7 and 8 5 to 8 range S osctl u gp1 a 5 6 gt adds ports 5 amp 6 to existing group gp1 osctl u gp1 a 7 gt adds port 7 to existing group gp1 S osctl u gp1 r 2 4 gt removes ports 2 amp 4 from group gp1 S osctl d gp1 gt deletes group gp1 and release all ports which were part of the group S osctl l gt lists ports in group like GroupName l
