Gateway Commands
A gateway is a network point that acts as an entrance to another network. On the Internet,
a node or stopping point can be either a gateway node or a host (end-point) node. Both the
computers of Internet users and the computers that serve pages to users are host nodes.
The computers that control traffic within your company’s network or at your local Internet
service provider (ISP) are gateway nodes.
In the network for an enterprise, a computer server acting as a gateway node is often also
acting as a proxy server and a firewall server. A gateway is often associated with both a
router, which knows where to direct a given packet of data that arrives at the gateway, and
a switch, which furnishes the actual path in and out of the gateway for a given packet.
Important: • The following Gateway commands were initially released with the 1.10
firmware. You must have firmware version 1.10 or later installed to be
able to access these commands.
• Gateway definitions are not persistent through a reset until the user
invokes the save command. Typing save at the command prompt will
update the Flash RAM, including the current netmask and gateway
settings.
GATEWAY [IPADDRESS] – Allows the user to set or query the default gateway address
(192.168.0.1) used by the chassis controller. When the command is issued without an
address, the current default gateway is returned. Supplying an IP address will set the
default gateway to that address.
Gateway commands evolved over several firmware releases. Differences between versions
are summarized in Table D-1.

Behavior Notes
1.10 Every time the GATEWAY command was issued with an IP address,
the address was added to a list of used gateways. These were only
cleared from the list on reset.
1.2x Gateways are added and removed by typing GATEWAY ADD
<ADDRESS> or GATEWAY DEL <ADDRESS>. These are still
tracked as a list of gateways.
2.00 or later Only one gateway is user-definable, and this is used by default.
Subsequent gateway definitions will replace the default gateway.
Other gateways are tracked automatically in response to received
ICMP redirect messages.
