packetFilter

The maximum length of a packet filter definition is 4096 bytes.

The editor assumes a terminal capability no higher than a glass tty (that is, it does not assume an addressable screen). You can place any ASCII printable character into the editing buffer at the cursor position. If a character exceeds the maximum line length, the character is discarded and a bell sounds. The editor initially operates in insert mode. The commands supported by the editor are summarized in Table 12-6.

To use the built-in line editor to create a packet filter definition:

1From the top level of the Administration Console, enter:

bridge packetFilter create

The packet filter line editor appears.

2Enter the definition for the packet filter. See the command in Table 12-6.

3Save the packet filter by pressing Ctrl+W.

The syntax of the filter definition is checked. If any errors are detected, the errors are displayed and the editor is re-entered at the line containing the first error. After correcting the errors, attempt to save the packet filter again.

After you have corrected all errors and successfully saved the packet filter, it is converted to internal form and stored on the system.
