single-ended rule edit optimized scps-discover
Edits a single-ended optimization rule for SCPS discovery.
Syntax
single-ended rule edit rulenum <rule-number> optimized scps-discover [srcaddr {<ip-address> | all-ip |all-ipv4 | all-ipv6}] [dstaddr {<ip-address> | all-ip |all-ipv4 | all-ipv6}] [dstport <port>] [allow-tcp-proxy {enable | disable}] [vlan <vlan>] [web-proxy <mode>] [cong-ctrl-algo <method>] [rate-pacing {enable | disable}]
Parameters
rulenum <rule-number>
Specifies a rule number to edit.
srcaddr <ip-address>
Specifies the source subnet IP address and netmask. Use the format XXX.XXX.XXX.XXX/XX for IPv4 and X:X:X::X/XXX for IPv6.
srcaddr all-ip
Specifies all IPv4 and all IPv6 addresses. This is the default.
srcaddr all-ipv4
Specifies all IPv4 addresses.
srcaddr all-ipv6
Specifies all IPv6 addresses.
dstaddr <ip-address>
Specifies the destination subnet IP address and netmask. Use the format XXX.XXX.XXX.XXX/XX for IPv4 and X:X:X::X/XXX for IPv6.
dstaddr all-ip
Specifies all IPv4 and all IPv6 addresses. This is the default.
dstaddr all-ipv4
Specifies all IPv4 addresses.
dstaddr all-ipv6
Specifies all IPv6 addresses.
dstport <port>
Specifies a destination port or port label for this rule. You can specify:
•  a single port number.
•  a comma-separated list of ports with or without ranges (for example, 1,2,4-10,12).
•  any user-defined port labels. Valid port labels include:
–  SteelFusion
–  Interactive
–  RBT-Proto
–  Secure
For more information on port labels, see port-label.
allow-tcp-proxy enable
Allows only SCPS peering. This is the default.
allow-tcp-proxy disable
Allows SCPS and non-SCPS peering.
vlan <vlan>
Specifies a VLAN identification number from 1 to 4094, -1, or 0. -1 specifies that the rule applies to all VLANs; 0 specifies that the rule applies to untagged connections.
web-proxy <mode>
Specifies the web proxy optimization mode for this rule:
•  disable - Use this rule if the connection is not web-proxied.
•  enable - Use this rule if the connection is web-proxied.
•  ignore - Use this rule if it is unimportant whether or not the connection is web proxied.
Web proxy enables a client-side appliance with an autodiscovery or pass-through in-path rule to use a single-ended web proxy to transparently intercept all traffic bound to the Internet. Enabling the web proxy improves performance by providing optimization services such as web object caching and SSL decryption to enable content caching and logging services.
cong-ctrl-algo <method>
Specifies a method for congestion control for the rule:
•  default - Standard TCP optimization (RFC compliant).
•  hstcp - High-speed TCP optimization.
•  bw-est - TCP bandwidth-estimation optimization.
•  per-conn-tcp - SkipWare per-connection TCP. This method is not available without a SCPS license.
•  err-tol-tcp - SkipWare error-tolerant TCP optimization. This method is not available without an SCPS license.
rate-pacing enable
Enables rate pacing on a per-rule basis.
Rate pacing is disabled by default. Rate pacing applies only to MX-TCP traffic as classified by QoS.
Enabling rate pacing evenly spreads the transmission of a window of packets across the entire duration of the round-trip time.
rate-pacing disable
Disables rate pacing on a per-rule basis.
Rate pacing is disabled by default. Rate pacing applies only to MX-TCP traffic as classified by QoS.
Usage
Use this command to edit the rules defined by the single-ended rule optimized scsp-discover command.
Use the no single-ended rule <rule> to remove a rule.
