Managing a Switch

Configuring the Switch IP Parameters
If the AT-9006 Series Switch is in a TCP/IP network and you want to
manage the switch remotely, such as with a Telnet utility or a web
browser, you must assign the switch a set of IP parameters, such as a
unique IP address and a subnet mask. You can assign these parameters
either one of two ways:
❑ Manually using the Omega interface
❑ Automatically using a BootP or DHCP server.
If you have a BootP or DHCP server on your network, the switch can
automatically obtain its IP parameters from the server during startups. In
this case, you simply connect the switch to the network. The function of
the BootP or DHCP utility within an IP server is to provide IP parameters,
including an IP address, to the switch. Whenever you reset or power
cycle the switch, the switch transmits a request packet to the server
every three seconds to obtain the required IP parameters.
The switch makes three request attempts. If the requesting switch does
not receive a BootP or DHCP response after the third request, it will
operate with a computed pseudo IP address based on the switch’s MAC
address.
If the switch receives a response from the BootP or DHCP server, the
switch extracts the IP address, subnet mask, and gateway/router address
and uses these parameters to configure itself until the next power-on or
reset. Additionally, if the BootP response packet specifies a filename and
a server address, then the switch sends a request to the server using the
specified filename. This initiates a download of the operating software
and allows you to maintain the downloaded software on your server.
