RARP Target MAC Match: Specify whether frames can hit the action according to their target
hardware address (THA) field settings. 0: RARP frames where THA is not equal to the target MAC
address. 1: RARP frames where THA is equal to the target MAC address. Any: Any value is allowed
("don't-care").
IP/Ethernet Length: Specify whether frames can hit the action according to their ARP/RARP hardware
address length (HLN) and protocol address length (PLN) settings. 0: ARP/RARP frames where the HLN
is not equal to Ethernet (0x06) or the (PLN) is not equal to IPv4 (0x04). 1: ARP/RARP frames where the
HLN is equal to Ethernet (0x06) and the (PLN) is equal to IPv4 (0x04). Any: Any value is allowed
("don't-care").
IP: Specify whether frames can hit the action according to their ARP/RARP hardware address space
(HRD) settings. 0: ARP/RARP frames where the HLD is not equal to Ethernet (1). 1: ARP/RARP frames
where the HLD is equal to Ethernet (1). Any: Any value is allowed ("don't-care").
Ethernet: Specify whether frames can hit the action according to their ARP/RARP protocol address
space (PRO) settings. 0: ARP/RARP frames where the PRO is not equal to IP (0x800). 1: ARP/RARP
frames where the PRO is equal to IP (0x800). Any: Any value is allowed ("don't-care").
IPv4 Parameters
The IP parameters can be configured when Frame Type "IPv4" is selected.
IP Protocol Filter: Specify the IP protocol filter for this ACE. Any: No IP protocol filter is specified
("don't-care"). ICMP: Select ICMP to filter IPv4 ICMP protocol frames. Extra fields for defining ICMP
parameters will appear. These fields are explained later in this section. UDP: Select UDP to filter IPv4
UDP protocol frames. Extra fields for defining UDP parameters will appear. These fields are explained
later in this section. TCP: Select TCP to filter IPv4 TCP protocol frames. Extra fields for defining TCP
parameters will appear. These fields are explained later in this section. Other: If you want to filter
another specific IP protocol filter with this ACE, choose this value. A field for entering an IP protocol
filter displays.
IP Protocol Value: When "Specific" is selected for the IP protocol value, you can enter a specific value.
The valid range is 0 to 255. A frame that hits this ACE matches this IP protocol value.
IP TTL: Specify the Time-to-Live settings for this ACE. Zero: IPv4 frames with a Time-to-Live field
greater than zero must not be able to match this entry. Non-zero: IPv4 frames with a Time-to-Live field
greater than zero must be able to match this entry. Any: Any value is allowed ("don't-care").
IP Fragment: Specify the fragment offset settings for this ACE. This involves the settings for the More
Fragments (MF) bit and the Fragment Offset (FRAG OFFSET) field for an IPv4 frame. No: IPv4 frames
where the MF bit is set or the FRAG OFFSET field is greater than zero must not be able to match this
entry. Yes: IPv4 frames where the MF bit is set or the FRAG OFFSET field is greater than zero must be
able to match this entry. Any: Any value is allowed ("don't-care").
IP Option: Specify the options flag setting for this ACE. No: IPv4 frames where the options flag is set
must not be able to match this entry. Yes: IPv4 frames where the options flag is set must be able to
match this entry. Any: Any value is allowed ("don't-care").
SIP Filter: Specify the source IP filter for this ACE. Any: No source IP filter is specified. (Source IP filter is
"don't-care".) Host: Source IP filter is set to Host. Specify the source IP address in the SIP Address field
that appears. Network: Source IP filter is set to Network. Specify the source IP address and source IP
mask in the SIP Address and SIP Mask fields that appear.
SIP Address: When "Host" or "Network" is selected for the source IP filter, you can enter a specific SIP
address in dotted decimal notation.
SIP Mask: When "Network" is selected for the source IP filter, you can enter a specific SIP mask in
dotted decimal notation.
DIP Filter: Specify the destination IP filter for this ACE. Any: No destination IP filter is specified.
(Destination IP filter is "don't-care".) Host: Destination IP filter is set to Host. Specify the destination IP
address in the DIP Address field that appears. Network: Destination IP filter is set to Network. Specify
