The ACE Configuration page includes the following fields:
Object Description
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 a 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
255
.
Policy Bitmask
When "Specific" is selected for the policy filter, you can enter a specific policy bitmask.
The allowed range is
0x0
to
0xff
. 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.
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).
