Correcting errors
in a packet filter
You can use the LANplex system line editor to edit packet filters. Once you
save the packet filter, it is checked for syntax errors. The LANplex system
software will not allow you to assign the packet filter to any slots until the
filter is error-free.
You can also edit a packet filter using an ASCII-based text editor such as
EMACS or vi. You can then use ftp to send the filter text onto the LANplex
system from a networked workstation.
To edit a packet filter:
1 From the top level of the Administration Console, enter:
bridge packetFilter edit
2 Enter the packet filter id number.
Specifying a filter id loads that filter into the edit buffer.
3 Edit the filter. For more information see the section "Using the Built-in Line
Editor" on page 14-19.
