config access_profile profile_id (ipv6)
ipv6 - Specifies that the Switch will look into the IPv6 fields in each packet, with emphasis on
one or more of the following fields:
• class <value 0-255> - Entering this parameter will instruct the Switch to examine the
class field of the IPv6 header. This class field is a part of the packet header that is
similar to the Type of Service (ToS) or Precedence bits field in IPv4.
• flowlabel <hex 0x0-fffff> - Entering this parameter will instruct the Switch to examine the
flow label field of the IPv6 header. This flow label field is used by a source to label
sequences of packets such as non-default quality of service or real time service
packets. This field is to be defined by the user in hex form.
• source_ipv6 <ipv6addr> - Specifies an IP address mask for the source IPv6 address.
• destination_ipv6 <ipv6addr> - Specifies an IP address mask for the destination IPv6
address.
port <portlist> | all - The access profile for Ethernet may be defined for each port on the
Switch. Up to 128 rules may be configured for each port. Selecting all will configure this rule
for all ports on the Switch. The port list is specified by listing the lowest switch number and the
beginning port number on that switch, separated by a colon. Then the highest switch number,
and the highest port number of the range (also separated by a colon) are specified. The
beginning and end of the port list range are separated by a dash. For example, 1:3 specifies
switch number 1, port 3. 2:4 specifies switch number 2, port 4. 1:3-2:4 specifies all of the
ports between switch 1, port 3 and switch 2, port 4 − in numerical order. Non-contiguous
portlist entries are separated by a comma. (ex: 1:1-1:3,1:7-1:9)
permit – Specifies that packets that match the access profile are permitted to be forwarded by
the Switch.
• priority <value 0-7> − This parameter is specified to re-write the 802.1p default priority
previously set in the Switch, 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 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.
deny – Specifies that packets that match the access profile are not permitted to be forwarded
by the Switch and will be filtered.
rx_rate - Use this to limit Rx bandwidth for the profile being configured. This rate is
implemented using the following equation – 1 value = 64kbit/sec. (ex. If the user selects a rx
rate of 10 then the ingress rate is 640kbit/sec.) The user many select a value between 1-
156249 or no limit. The default setting is no limit.
counter [enable | disable] – Use this parameter to enable the counter function. When enabled,
this counter will count the number of packets that match the profile stated with this command.
If the counter command is enabled using the flow_meter command, the conter command here
will be overridden and therefore will not count packets. This command is optional and the
default setting is disabled.
mirror - Selecting mirror specifies that packets that match the access profile are mirrored to a
port defined in the config mirror port command. Port Mirroring must be enabled and a target
port must be set. Remember, Port Mirroring cannot cross-box, that is they cannot span across
switches in a switch stack.
{time_range <range_name 32>} – Choose this parameter and enter the name of the Time
Range settings that has been previously configured using the config time_range command.
This will set specific times when this access rule will be enabled or disabled on the Switch.
delete access_id <value 1-128> − Use this command to delete a specific rule from the IPv6
profile. Up to 128 rules may be specified for the IPv6 access profile.
Restrictions Only administrator-level users can issue this command.
