Table 23: FilterStats Parameters (continued)
Parameter
Description
Bad State Alloc
Number of failed attempts to allocated State
In
table entries for inbound packets. This occurs
when a filter rule is declared using the 'keep
state' option. Packets that match the rule
cause a State table entry to be allocated. This
allows expected return packets to bypass
other filtering rules that might normally block
them. Allocation fails if the State table is full
and a new entry cannot be allocated.
Bad State Alloc
Number of failed attempts to allocated State
Out
table entries for outbound packets. This occurs
when a filter rule is declared using the 'keep
state' option. Packets that match the rule
cause a State table entry to be allocated. This
allows expected return packets to bypass
other filtering rules that might normally block
them. Allocation fails if the State table is full
and a new entry cannot be allocated.
Keep State
Number of successful attempts to allocated
Alloc In
State table entries for inbound packets. This
occurs when a filter rule is declared using the
'keep state' option. Packets that match the rule
cause a State table entry to be allocated. This
allows expected return packets to bypass
other filtering rules that might normally block
them.

cause a State table entry to be allocated. This
allows expected return packets to bypass
other filtering rules that might normally block

Cache Hit In
Number of cache hits for inbound packets on
this interface. Each inbound packet is
examined to see if a packet with identical
characteristics exists in the outbound cache
for this interface. If a match is found, the
resulting rule match applied to the previous
packet is applied to the current one, bypassing
the rest of the filtering mechanism.
