ACE Configuration Help

Configure an ACE (Access Control Entry) on this page.

An ACE consists of several parameters. These parameters vary according to the frame type that you select. First select the ingress port for the ACE, and then select the frame type. Different parameter options are displayed depending on the frame type selected.

A frame that hits this ACE matches the configuration that is defined here.

Lookup: Specify the second lookup operation of the ACE.
Ingress Port: Select the ingress port for which this ACE applies.
All: The ACE applies to all port.
Port n: The ACE applies to this port number, where n is the number of the switch port.
Policy Filter: Specify the policy number filter for this ACE.
Any: No policy filter is specified. (policy filter status is "don't-care".)
Specific: If you want to filter a specific policy with this ACE, choose this value. Two field for entering an policy value and bitmask appears.
Policy Value: When "Specific" is selected for the policy filter, you can enter a specific policy value. The allowed range is 0 to 0.
Policy Bitmask: When "Specific" is selected for the policy filter, you can enter a specific policy bitmask. The allowed range is 0x0 to 0x7. Notice the usage of bitmask, if the binary bit value is "0", it means this bit is "don't-care". The real matched pattern is [policy_value & policy_bitmask]. For example, if the policy value is 3 and the policy bitmask is 0x10(bit 0 is "don't-care" bit), then policy 2 and 3 are applied to this rule.
Switch: Select the switch to which this ACE applies.
Any: The ACE applies to any port.
Switch n: The ACE applies to this switch number, where n is the number of the switch.
Frame Type: Select the frame type for this ACE. These frame types are mutually exclusive.
Any: Any frame can match this ACE.
Ethernet Type: Only Ethernet Type frames can match this ACE. The IEEE 802.3 describes the value of Length/Type Field specifications to be greater than or equal to 1536 decimal (equal to 0600 hexadecimal).
ARP: Only ARP frames can match this ACE. Notice the ARP frames won't match the ACE with ethernet type.
IPv4: Only IPv4 frames can match this ACE. Notice the IPv4 frames won't match the ACE with ethernet type.; IPv6: Only IPv6 frames can match this ACE. Notice the IPv6 frames won't match the ACE with Ethernet type.
Action: Specify the action to take with a frame that hits this ACE.
Permit: The frame that hits this ACE is granted permission for the ACE operation.
Deny: The frame that hits this ACE is dropped.
Filter: Frames matching the ACE are filtered.
Rate Limiter: Specify the rate limiter in number of base units. The allowed range is 1 to 15. Disabled indicates that the rate limiter operation is disabled.

Port Redirect: Frames that hit the ACE are redirected to the port number specified here. The rate limiter will affect these ports. The allowed range is the same as the switch port number range. Disabled indicates that the port redirect operation is disabled and the specific port number of 'Port Redirect' can't be set when action is permitted.
Port Redirect: Frames that hit the ACE are redirected to the port number specified here. The rate limiter will affect these ports. The allowed range is the same as the switch port number range. Disabled indicates that the port redirect operation is disabled and the specific port number of 'Port Redirect' can't be set when action is permitted.
Port Redirect: Frames that hit the ACE are redirected to the port number specified here. The rate limiter will affect these ports. The allowed range is the same as the switch port number range. Disabled indicates that the port redirect operation is disabled and the specific port number of 'Port Redirect' can't be set when action is permitted.
Mirror: Specify the mirror operation of this port. Frames matching the ACE are mirrored to the destination mirror port. The rate limiter will not affect frames on the mirror port. The allowed values are:
Enabled: Frames received on the port are mirrored.
Disabled: Frames received on the port are not mirrored.
The default value is "Disabled".
Logging: Specify the logging operation of the ACE. Notice that the logging message doesn't include the 4 bytes CRC information. The allowed values are:

Shutdown: Specify the port shut down operation of the ACE. The allowed values are:
Enabled: If a frame matches the ACE, the ingress port will be disabled.
Disabled: Port shut down is disabled for the ACE.
Note: The shutdown feature only works when the packet length is less than 1518(without VLAN tags).
