Table 21-6 Cable Modem Packet Filter Group Details Window
Parameter Description
Group ID Group number specifies the ID of the filter group to which you
want the filter to belong. Allowable values range from 1 to
60.
Filter ID Filter number specifies the index number for the filter within
the group. Allowable values range from 1 to 40.
Action Action to take upon this filter matching. The options are:
Permit Forward the packet for further processing. The default is to
permit the packet.
Deny Drop the packet.
Protocol The protocol that the filter attempts to match. Specify one of
the following protocols: TCP, UDP, Any, and Number.
■ You may obtain protocol numbers from the Internet
Assigned Numbers Authority (IANA) at www.iana.org.
■ You may specify a protocol number from 0 to 256. Note
that specifying 256 is the same as specifying “Any.”
TOS Value The two-digit hexadecimal number indicating the Type of
Service (ToS) value to be matched against the ToS value in IP
packets (for example, 0a). The default is 00.
TOS Mask The two-digit hexadecimal number that specifies the mask to
be applied to the TOS value matched in the IP packet (for
example 1b). The mask determines which bits are matched (a
0 specifies a match while a 1 specifies no match).
The default is 00, which means that the ToS value you specify
is matched against all TOS values in IP packets.
Src Address The filter attempts to match the source IP address to the IP
address in the IP packet. If the addresses match, the filter is
applied to the packet.
Src Mask Bit mask that applies to the source IP address prior to
matching. The source IP address and mask are the matching
criteria for the packet. By default, the source IP address and
mask specify a filter that matches all source addresses. This
mask entry is not necessarily the same as the subnet mask.
Dest Add The filter attempts to match the destination IP address to the
IP address in the IP packet. If the addresses match, the filter is
applied to the packet.
