Configuring A Source-Port Traffic Filter - HP E3800-24G-PoE+-2SFP+ Access Security Manual

Configuring a Source-Port Traffic Filter

Syntax: [no] filter
[source-port < port-number | trunk-name>]
Specifies one inbound port or trunk. Traffic received
inbound on this interface from other devices will be
filtered. The no form of the command deletes the source-
port filter for < port-number > and returns the destination
ports for that filter to the Forward action. (Default:
Forward on all ports.)
Note: If multiple VLANs are configured, the source-port
and the destination port(s) must be in the same VLAN
unless routing is enabled. Similarly, if a VLAN
containing both the source and destination is multi-
netted, the source and destination ports and/or trunks
must be in the same subnet unless routing is enabled.
[ drop ] < destination-port-list > [ forward < port-list >]
Configures the filter to drop traffic for the ports and/or
trunks in the designated < destination-port-list >. Can be
followed by forward < destination-port-list > if you have
other destination ports set to drop that you want to
change to forward. If no drop or forward action is
specified, the switch automatically creates a filter with
a forward action from the designated source port (or
trunk) to all destination ports (or trunks) on the switch.
[ forward ] < port-list >
Configures the filter to forward traffic for the ports and/
or trunks in the designated < destination-port-list >.
Because forward is the default state for destinations in
a filter, this command is useful when destinations in
an existing filter are configured for drop and you want
to change them to forward. Can be followed by drop
< destination-port-list > if you have other destination
ports set to forward that you want to change to drop. If
no drop or forward action is specified, the switch
automatically creates a filter with a forward action
from the designated source port (or trunk) to all desti-
nation ports (or trunks) on the switch.
