Named Source-Port Filters
You can specify named source-port filters that may be used on multiple ports
and port trunks. A port or port trunk can only have one source-port filter, but
by using this capability you can 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.
Switch
Server "A"
Port 7
Port 8
Server "B"
Port 9
Server "C"
Port 5
Workstation " X"
This list shows the filter created
to block (drop) traffic from
source port 5 (workstation "X") to
destination port 7 (server "A").
Notice that the filter allows
traffic to move from source port
5 to all other destination ports.
