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  |
