Using Source-Port Filters
Viewing a Source-Port Filter
You can list all source-port filters configured in the switch and, optionally, the
detailed information on a specific filter.
For example, assume that these three filters exist on the switch:
Syntax: show filter [index]
Displays a listing of configured filters, where each filter
entry includes an IDX (index) number, Filter Type, and
Value :
IDX: An automatically assigned index number used to
identify the filter for a detailed information listing. A
filter retains its assigned IDX number for as long as the
filter exists in the switch. The switch assigns the lowest
available IDX number to a new filter. This can result in
a newer filter having a lower IDX number than an older
filter if a previous (source-port) filter deletion created
a gap in the filter listing.
Filter Type: Indicates the type of filter assigned to the
IDX number.
Value: Indicates the port number or port-trunk name
of the source port or trunk assigned to the filter.
Use show filter to learn the index number of a specific
filter you want to examine in more detail.
[ index ]
Displays detailed data on the filter designated by the index
number. For source-port filters, the display includes the
source-port number, a listing of all ports and/or trunks on
the switch (with their port types), and the filter action
configured on each port or trunk (Forward—the default—
or Drop).
