Traffic/Security Filters (ProCurve Series 2600/2600-PWR and 2800 Switches) Using Source-Port Filters
Syntax: filter source-port named-filter <filter-name> drop < destination-port-list>
Configures the named source-port filter to drop traffic having a destination on the ports and/or port trunks in the < destination-port-list>. Can be followed by the forward option if you have other destination ports or port trunks previously set to drop that you want to change to forward. For example:
filter source-port named-filter <filter-name> drop < destination-port-list> forward < destination-port-list>
The destination-port-listmay contain ports, port trunks, and ranges (for example 3- 7 or trk4-trk9) separated by commas.
Syntax: filter source-port named-filter <filter-name> forward < destination-port-list>
Configures the named source-port filter to forward traffic having a destination on the ports and/or port trunks in the
<destination-port-list>. Since "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 the drop option if you have other destination ports set to forward that you want to change to drop. For example:
filter source-port named-filter <filter-name> forward < destination-port-list> drop
<destination-port-list >
A named source-port filter must first be defined and configured before it can be applied. In the following example two named source-port filters are defined, web-onlyand accounting.
ProCurve(config)# filter source-port named-filter web- only
ProCurve(config)# filter source-port named-filter accounting
By default, these two named source-port filters forward traffic to all ports and port trunks.
To configure a named source-port filter to prevent inbound traffic from being forwarded to specific destination switch ports or port trunks, the drop option is used. For example, on a 26-port switch, to configure the named source-port filter web-onlyto drop any traffic except that for destination ports 1 and 2, the following command would be used:
ProCurve(config)# filter source-port named-filter web- only drop 3-26
A named source-port filter can be defined and configured in a single command by adding the drop option, followed by the required destination-port-list.
