Filtering
Table A13-4 lists valid keywords and values for the add subcommand’s criteria argument. The
syntax is:
keyword value
actions Specifies what a filter does when all of its criteria match a
packet. You can specify any combination of actions. Possible
actions are:
discard Discards the packet. Discarding is done after any syslog, icmp,
or netact actions are taken.
icmp Discards the packet and sends an ICMP destination
unreachable message.
netact If the link is quiescent, netact discards the packet.
no_start Used only with dynamic dial-out networking. If used in an
include filter, the no_start filter action specifies that traffic
defined as activity on the specified interface will not activate a
dynamic dial-out line. However, the filter action will keep the
line up if it is already up–that is, if it is not quiescent. In the
process, the action resets the net_inactivity timer to 0. See
Dial-up Networking, starting on page A11-1, for information
on dynamic dialing.
syslog Logs the event in the system log file.
NOTE:
Filters that would cause multiple syslog, icmp, and netact
actions for the same interface are reduced to a single syslog, icmp, or
netact action. To add a dynamic dial-out filter, configure the %dialout
section of the Model 5390 configuration file; you cannot add the filter
using the filter command (see Creating dialout Entries in the Configu-
ration File on page A14-37).
