ETH IP DISABLE
Disables IP routing across the Ethernet LAN. This commands acts as a master switch allowing you to disable all
IP routing for testing or control purposes.
Note: This command requires a save and reboot before it is effective.
ETH IP ENABLE
Enables IP routing across the Ethernet LAN. This command acts as a master switch allowing you to re-enable all
IP routing.
Note: This command requires a save and reboot before it is effective.
ETH IP FILTER
Manages the IP filters for the Ethernet interface(s). The filters are used to screen IP packets.
Each Ethernet interface can have its own set of filters. The intended interface is designated at the end of the filter
command. If the router has two physical Ethernet interfaces (an Ethernet hub router), the interface is designated
by its port number (0 or 1). If logical interfaces have been defined to provoide service to multiple IP subnets, the
logical interface number is also specified (port #:<logical #, for example, 0:1).
The set of filters for an interface can be of three types: Input, Forward, and Output. For more information on how
these three types of filters are applied, refer to Chapter 4. IP Filtering on page 103..
Note: IP filters take effect immediately upon entry. They can even affect the current connection that you are using
to enter commands. Unlike other configuration changes, you do not need to save and reboot.
The following commands are provided for managing IP filters for an Ethernet interface:
eth ip directedbcast on | off
on Enables the forwarding of packets.
off Disables the forwarding of packets.
Example:
eth ip directedbcast on
eth ip disable
Example:
eth ip disable
eth ip enable
Example:
eth ip enable
eth ip filter <command> <type> <action> [<parameters>] [<interface>]
