The following operations can be performed on "lsn transportprofile":

add | rm | set | unset | show

add lsn transportprofile

Add LSN Transport Profile.

Synopsys

add lsn transportprofile <transportprofilename> <transportprotocol> [-sessiontimeout <secs>] [-finrsttimeout <secs>] [-stuntimeout <positive_integer>] [-synidletimeout <positive_integer>] [-portquota <positive_integer>] [-sessionquota <positive_integer>] [-groupSessionLimit <positive_integer>] [-portpreserveparity ( ENABLED | DISABLED )] [-portpreserverange ( ENABLED | DISABLED )] [-syncheck ( ENABLED | DISABLED )]

Arguments

transportprofilename

Name for the LSN transport profile. Must begin with an ASCII alphanumeric or underscore (_) character, and must contain only ASCII alphanumeric, underscore, hash (#), period (.), space, colon (:), at (@), equals (=), and hyphen (-) characters. Cannot be changed after the LSN transport profile is created. The following requirement applies only to the NetScaler CLI: If the name includes one or more spaces, enclose the name in double or single quotation marks (for example, "lsn transport profile1" or 'lsn transport profile1').

transportprotocol

Protocol for which to set the LSN transport profile parameters.

Possible values: TCP, UDP, ICMP

sessiontimeout

Timeout, in seconds, for an idle LSN session. If an LSN session is idle for a time that exceeds this value, the NetScaler ADC removes the session.

This timeout does not apply for a TCP LSN session when a FIN or RST message is received from either of the endpoints.

Default value: 120

Minimum value: 60

finrsttimeout

Timeout, in seconds, for a TCP LSN session after a FIN or RST message is received from one of the endpoints.

If a TCP LSN session is idle (after the NetScaler ADC receives a FIN or RST message) for a time that exceeds this value, the NetScaler ADC removes the session.

Since the LSN feature of the NetScaler ADC does not maintain state information of any TCP LSN sessions, this timeout accommodates the transmission of the FIN or RST, and ACK messages from the other endpoint so that both endpoints can properly close the connection.

Default value: 30

stuntimeout

STUN protocol timeout

Default value: 600

Minimum value: 120

Maximum value: 1200

synidletimeout

SYN Idle timeout

Default value: 60

Minimum value: 30

Maximum value: 120

portquota

Maximum number of LSN NAT ports to be used at a time by each subscriber for the specified protocol. For example, each subscriber can be limited to a maximum of 500 TCP NAT ports. When the LSN NAT mappings for a subscriber reach the limit, the NetScaler ADC does not allocate additional NAT ports for that subscriber.

Default value: 0

Minimum value: 0

Maximum value: 65535

sessionquota

Maximum number of concurrent LSN sessions allowed for each subscriber for the specified protocol.

When the number of LSN sessions reaches the limit for a subscriber, the NetScaler ADC does not allow the subscriber to open additional sessions.

Default value: 0

Minimum value: 0

Maximum value: 65535

groupSessionLimit

Maximum number of concurrent LSN sessions(for the specified protocol) allowed for all subscriber of a group to which this profile has bound. This limit will get split across the netscalers packet engines and rounded down. When the number of LSN sessions reaches the limit for a group in packet engine, the NetScaler ADC does not allow the subscriber of that group to open additional sessions through that packet engine.

Default value: 0

Minimum value: 0

portpreserveparity

Enable port parity between a subscriber port and its mapped LSN NAT port. For example, if a subscriber initiates a connection from an odd numbered port, the NetScaler ADC allocates an odd numbered LSN NAT port for this connection.

You must set this parameter for proper functioning of protocols that require the source port to be even or odd numbered, for example, in peer-to-peer applications that use RTP or RTCP protocol.

Possible values: ENABLED, DISABLED

Default value: DISABLED

portpreserverange

If a subscriber initiates a connection from a well-known port (0-1023), allocate a NAT port from the well-known port range (0-1023) for this connection. For example, if a subscriber initiates a connection from port 80, the NetScaler ADC can allocate port 100 as the NAT port for this connection.

This parameter applies to dynamic NAT without port block allocation. It also applies to Deterministic NAT if the range of ports allocated includes well-known ports.

When all the well-known ports of all the available NAT IP addresses are used in different subscribers\? connections (LSN sessions), and a subscriber initiates a connection from a well-known port, the NetScaler ADC drops this connection.

Possible values: ENABLED, DISABLED

Default value: DISABLED

syncheck

Silently drop any non-SYN packets for connections for which there is no LSN-NAT session present on the NetScaler ADC.

If you disable this parameter, the NetScaler ADC accepts any non-SYN packets and creates a new LSN session entry for this connection.

Following are some reasons for the NetScaler ADC to receive such packets:

• LSN session for a connection existed but the NetScaler ADC removed this session because the LSN session was idle for a time that exceeded the configured session timeout.

• Such packets can be a part of a DoS attack.

Possible values: ENABLED, DISABLED

Default value: ENABLED

Example

add lsn transportprofile profile1 TCP -portquota 128

rm lsn transportprofile

Remove LSN Transport Profile.

Synopsys

rm lsn transportprofile <transportprofilename>

Arguments

transportprofilename

Name for the LSN transport profile. Must begin with an ASCII alphanumeric or underscore (_) character, and must contain only ASCII alphanumeric, underscore, hash (#), period (.), space, colon (:), at (@), equals (=), and hyphen (-) characters. Cannot be changed after the LSN transport profile is created. The following requirement applies only to the NetScaler CLI: If the name includes one or more spaces, enclose the name in double or single quotation marks (for example, "lsn transport profile1" or 'lsn transport profile1').

rm lsn transportprofile profile1
