Field | Description |
| Default |
|
|
|
|
Field | Either TYPE, IP, MAC, or SR (see Field Offset |
|
|
description). The origin is the field from which the |
| TYPE | |
Origin |
| ||
offset count starts. |
|
| |
|
|
| |
|
|
|
|
| The decimal offset of the portion of the packet to be |
|
|
| examined. If the origin is TYPE, the field offset value is |
|
|
| relative to the end of the Ethernet frame type, |
|
|
| regardless of whether or not the frame type is SNAP |
|
|
| encapsulated. For example, for IP packets, a field |
|
|
| origin of TYPE with a field offset of zero indicates the |
|
|
| start of the IP header. |
|
|
Field | If the origin is IP, then the offset is relative to the end of |
|
|
the IP Header (an offset of zero indicates the portion |
|
| |
Offset |
|
| |
immediately following the end of the IP Header). |
|
| |
|
|
| |
| If the origin is MAC, then the offset is relative to the |
|
|
| beginning of the MAC addresses (an offset of zero |
|
|
| indicates the start of the destination MAC address). |
|
|
| If the origin is SR, then the offset is relative to the end |
|
|
| of the MAC header, including the Source Routing (SR) |
|
|
| header, if present. |
|
|
|
|
|
|
| The two digit hexadecimal value of each of the eight |
|
|
| octets beginning at the origin and offset by the value |
|
|
Field | specified above. The octets must be separated by |
|
|
Value | spaces. This is the value that the filter is using when it |
|
|
| does a comparison for a match, for example a MAC |
|
|
| address. |
|
|
|
|
|
|
| An eight octet mask applied to the packet’s eight |
|
|
Field | octets before comparing them to the Field Value |
|
|
Mask | specified above. The mask octets must be separated |
|
|
| by spaces. This is a mask of the specified Field Value. |
|
|
|
|
|
|
| Filter number for this filter. For example, a value of one |
|
|
| indicates that this is the first filter in the Filter Table. If |
|
|
Filter | you use the default index of 1, any other filters you |
|
|
have previously defined will be renumbered starting |
| One | |
Index |
| ||
with 2. Although filters are assigned to a port, filter |
|
| |
|
|
| |
| indexes are not; they are assigned sequentially to all |
|
|
| filters for all ports. |
