Traffic/Security Filters (ProCurve Series 2600/2600-PWR and 2800 Switches)
Using Source-Port Filters
Using Named Source-Port Filters
This feature is available only on the Series 2600 and 2600-PWR switches.
Named source-port filters are filters that may be used on multiple ports and
port trunks. As with regular source-port filters, a port or port trunk can only
have one source-port filter, but this new capability enables you to define a
source-port filter once and apply it to multiple ports and port trunks. This can
make it easier to configure and manage source-port filters on your switch. The
commands to define, configure, apply, and display the status of named
source-port filters are described below.
Operating Rules for Named Source-Port Filters
■ A port or port trunk may only have one source-port filter, named or
not named.
■ A named source-port filter can be applied to multiple ports or port
trunks.
■ Once a named source-port filter is defined, subsequent changes only
modify its action, they don’t replace it.
■ To change the named source-port filter used on a port or port trunk,
the current filter must first be removed, using the
no filter source-port
named-filter <filter-name > command.
■ A named source-port filter can only be deleted when it is not applied
to any ports.
Defining and Configuring Named Source-Port Filters
The named source-port filter command operates from the global configuration
level.
Syntax: [no] filter source-port named-filter <filter-name>
Defines or deletes a named source-port filter. The filter-name may contain a maximum
of 20 alpha-numeric characters (longer names may be specified, but they are not
displayed). A filter-name cannot be a valid port or port trunk name.
The maximum number of named source-port filters that can be used is equal to the
number of ports on a switch.
A named source-port filter can only be removed if it is not in use (use the show filter
source-port command to check the status). Named source-port filters are not
automatically deleted when they are no longer used.
Use the
no option to delete an unused named source-port filter.
