tcp sat-opt scps rule
Configures Space Communications Protocol Standards (SCPS) rules for satellite optimization.
Syntax
[no] tcp sat-opt scps rule [srcaddr <network>] [dstaddr <network>] [dstport <port>] [allow-scps {enable | disable}] [scps-peer-only {enable | disable}] [vlan <tag-id>] [cong-ctrl-algo <method>] [rate-pacing {enable | disable}] [rulenum <rule-number>]
Parameters
srcaddr <network>
Specifies an IPv4 address and mask for the traffic source. Use the format XXX.XXX.XXX.XXX/XX.
dstaddr <network>
Specifies an IPv4 address and mask for the traffic destination. Use the format XXX.XXX.XXX.XXX/XX.
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 details on port labels, see port-label.
allow-scps
Specifies an SCPS mode for this rule.
enable - Enables a rule to optimize single-ended interception SCPS connections.
disable - Disables a rule to optimize single-ended interception SCPS connections. If you choose this option, single-ended interception SCPS connections pass through the SteelHead unoptimized.
scps-peer-only
Specifies an SCPS peering rule.
enable - Allows SCPS peering for single-ended interception SCPS connections.
disable - Allows both SCPS and non-SCPS peering (for example, proxy fallback) for single-ended interception connections.
vlan <tag-id>
Specifies a VLAN tag ID for this rule.
1 to 4094
0 (for untagged)
-1 (for all)
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.
per-conn-tcp - SkipWare per-connection TCP. This is the default algorithm.
err-tol-tcp - SkipWare error-tolerant TCP optimization.
rate-pacing
Specifies whether to enable or disable rate pacing.
enable - Enables rate pacing.
disable - Disables rate pacing.
Rate pacing is disabled by default.
Enabling rate pacing evenly spreads the transmission of a window of packets across the entire duration of the round-trip time.
rulenum <rule-number>
Specifies the number or order in the SCPS rule table for this rule.
1 to N or start/end
Usage
Before configuring SCPS rules, you must have a valid SCPS license and you must enable the SCPS table using the tcp sat-opt scps scps-table enable command.
The no command option removes the rule. The no command option has the following syntax:
no tcp sat-opt scps rule <number>
Example
amnesiac (config) # tcp sat-opt scps rule srcaddr 1.1.1.1/32 dstaddr 2.2.2.2/32 allow-scps enable vlan 2000 rulenum 2
Product
SteelHead CX, SteelHead-v, SteelHead-c
