SIPv6 address. The field only supported last 32 bits for IPv6 address.
When "Specific" is selected for the source IPv6 filter, you can enter a specific
SIPv6 mask. The field only supported last 32 bits for IPv6 address. 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 [sipv6_address & sipv6_bitmask] (last 32 bits). For
example, if the SIPv6 address is 2001::3 and the SIPv6 bitmask is
0xFFFFFFFE(bit 0 is "don't-care" bit), then SIPv6 address 2001::2 and 2001::3
are applied to this rule.
Specify the hop limit settings for this ACE.
■
zero: IPv6 frames with a hop limit field greater than zero must not be able
to match this entry.
■
non-zero: IPv6 frames with a hop limit field greater than zero must be able
to match this entry.
■
Any: Any value is allowed ("don't-care").
Description
Specify the ICMP filter for this ACE.
■
Any: No ICMP filter is specified (ICMP filter status is "don't-care").
■
Specific: If you want to filter a specific ICMP filter with this ACE, you can
enter a specific ICMP value. A field for entering an ICMP value appears.
When "Specific" is selected for the ICMP filter, you can enter a specific ICMP
value.
The allowed range is 0 to 255. A frame that hits this ACE matches this ICMP
value.
Specify the ICMP code filter for this ACE.
■
Any: No ICMP code filter is specified (ICMP code filter status is
"don't-care").
■
Specific: If you want to filter a specific ICMP code filter with this ACE, you
can enter a specific ICMP code value. A field for entering an ICMP code
value appears.
When "Specific" is selected for the ICMP code filter, you can enter a specific
ICMP code value.
The allowed range is 0 to 255. A frame that hits this ACE matches this ICMP
code value.
