Example:

conn-max 256 random-sequence-number
disable
Sets maximum connection limits or whether TCP sequence
randomization is enabled.
The
conn-max
n
argument sets the maximum number of
simultaneous TCP and/or UDP connections that are allowed,
between 0 and 2000000. The default is 0, which allows unlimited
connections.
If two servers are configured to allow simultaneous TCP and/or
UDP connections, the connection limit is applied to each
configured server separately.
When configured under a class, this argument restricts the
maximum number of simultaneous connections that are allowed
for the entire class. In this case, one attack host can consume all
the connections and leave none of the rest of the hosts matched in
the access list under the class.
The
embryonic-conn-max
n
argument sets the maximum number
of simultaneous embryonic connections allowed, between 0 and
2000000. The default is 0, which allows unlimited connections.
The
per-client-embryonic-max
n
argument sets the maximum
number of simultaneous embryonic connections allowed per
client, between 0 and 2000000. The default is 0, which allows
unlimited connections.
The
per-client-max
n
argument sets the maximum number of
simultaneous connections allowed per client, between 0 and
2000000. The default is 0, which allows unlimited connections.
When configured under a class, this argument restricts the
maximum number of simultaneous connections that are allowed
for each host that is matched through an access list under the
class.
The
random-sequence-number
{
enable
|
disable
} keyword
enables or disables TCP sequence number randomization. See the
“TCP Sequence Randomization” section on page 1-3
section for
more information.
You can enter this command all on one line (in any order), or you
can enter each attribute as a separate command. The ASA
combines the command into one line in the running configuration.
Note
For management traffic, you can only set the
conn-max
and
embryonic-conn-max
keywords.
