Packet Filter Commands
This chapter describes the packet filter commands.
45.1 Packet Filter Commands
Use the following packet filter commands to filter out specific types of packets on specific
ports.
45.1.1 Packet Filter Show Command
Syntax:
ras> switch pktfilter show [portlist]
where
This command displays the packet type filter settings on the specified ADSL port(s) or on all
ADSL ports if no port is specified.
The following example displays the packet type filter settings for ADSL ports 1 and 2. “V”
displays for the packet types that the IES-1248-51 is to accept on the port. “-” displays for
packet types that the IES-1248-51 is to reject on the port (packet types that are not listed are
accepted). When you use PPPoE only,”#” appears for all of the packet types. With PPPoE
only, the IES-1248-51 rejects all packet types except for PPPoE (packet types that are not
listed are also rejected).
[portlist] =
You can specify a single ADSL port <1>, all ADSL ports <*>
or a list of ADSL ports <1,3,5>. You can also include a range of
ports <1,5,6~10>.
