xStack DES-6500 Modular Layer 3 Chassis Ethernet Switch CLI Manual
create access_profile (packet content mask)
Purpose
Used to create an access profile on the Switch by examining the
Ethernet part of the packet header. Packet content masks entered
will specify certain bytes of the packet header to be identified by the
Switch. When the Switch recognizes a packet with the identical byte
as the one configured, it will either forward or filter the packet, based
on the users command. Specific values for the rules are entered
using the
config access_profile
command, below.
Syntax
create access_profile packet_content_mask profile_id <value 1-
8> {offset_0-15 <hex 0x0-0xffffffff> <hex 0x0-0xffffffff> <hex
0x0-0xffffffff> <hex 0x0-0xffffffff> | offset_16-31 <hex 0x0-
0xffffffff> <hex 0x0-0xffffffff> <hex 0x0-0xffffffff> <hex 0x0-
0xffffffff> | offset_32-47 <hex 0x0-0xffffffff> <hex 0x0-0xffffffff>
<hex 0x0-0xffffffff> <hex 0x0-0xffffffff> | offset_48-63 <hex 0x0-
0xffffffff> <hex 0x0-0xffffffff> <hex 0x0-0xffffffff> <hex 0x0-
0xffffffff> | offset_64-79 <hex 0x0-0xffffffff> <hex 0x0-0xffffffff>
<hex 0x0-0xffffffff> <hex 0x0-0xffffffff>}
Description
This command is used to identify packets by examining the Ethernet
packet header, by byte and then decide whether to filter or forward it,
based on the user’s configuration. The user will specify which bytes
to examine by entering them into the command, in hex form, and
then selecting whether to filter or forward them, using the
config
access_profile
command.
Parameters
profile_id <value 1-8>
- Specifies an index number between 1 and 8
that will identify the access profile being created with this command.
packet_content_mask
– Specifies that the Switch will mask the
packet header beginning with the offset value specified as follows:
Restrictions Only
administrator-level users can issue this command.
•
offset_0-15
– Enter a value in hex form to mask the packet
from the beginning of the packet to the 15th byte.
•
offset_16-31
- Enter a value in hex form to mask the packet
from byte 16 to byte 31.
•
offset_32-47
- Enter a value in hex form to mask the packet
from byte 32 to byte 47.
•
offset_48-63
- Enter a value in hex form to mask the packet
from byte 48 to byte 63.
•
offset_64-79
- Enter a value in hex form to mask the packet
from byte 64 to byte 79.
Example usage:
To create an access profile by packet content mask:
DES-6500:4#create access_profile packet_content_mask offset_0-15
0xFFFFFFFF 0xFFFFFFFF 0xFFFFFFFF 0xFFFFFFFF offset_16-31 0xFFFF
0xFFFF0000 0xF 0xF000000 profile_id 3
Command: create access_profile packet_content_mask offset_0-15
0xFFFFFFFF 0xFFFFFFFF 0xFFFFFFFF 0xFFFFFFFF offset_16-31 0xFFFF
0xFFFF0000 0xF 0xF000000 profile_id 3
Success.
