config access_profile profile_id (IP)
which is used to determine the CoS queue to which packets
are forwarded to. Once this field is specified, packets accepted
by the Switch that match this priority are forwarded to the CoS
queue specified previously by the user.
•
{replace_priority}
−
Enter this parameter if you want to re-write
the 802.1p default priority of a packet to the value entered in
the Priority field, which meets the criteria specified previously
in this command, before forwarding it on to the specified CoS
queue. Otherwise, a packet will have its incoming 802.1p user
priority re-written to its original value before being forwarded by
the Switch.
replace_dscp <value 0-63>
−
Allows you to specify a value to be
written to the DSCP field of an incoming packet that meets the
criteria specified in the first part of the command. This value will
over-write the value in the DSCP field of the packet.
deny – Specifies that packets that do not match the access profile
are not permitted to be forwarded by the Switch and will be filtered.
delete access_id <value 1-100>
−
Use this command to delete a
specific rule from the IP profile. Up to 100 rules may be specified for
the IP access profile.
Restrictions Only administrator-level users can issue this command.
Example usage:
To configure a rule for the IP access profile:
DES-3800:4#config access_profile profile_id 2 add access_id 2 ip
protocol_id 2 port 1:2 deny
Command: config access_profile profile_id 2 add access_id 2 ip
protocol_id 2 port 1:2 deny
Success.
DES-3800:4#
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 {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>} profile_id <value 1-8>}
