no-text: Specifies to block advertisements. Mobile client users see the “cannot display image” icon (usually an X mark) instead of a blocked advertisement. Users cannot view the blocked advertisements even if they want to.
|
|
•
|
text-only text_only_string: Specifies to block advertisements. Mobile client users will see a placeholder frame instead of each blocked advertisement. Each placeholder frame contains the text specified here along with the advertisement’s URL. Users cannot view the blocked advertisements even if they want to.
|
text_only_string must be an alpha and/or numeric string of 1 through 255 characters in length.
|
•
|
text-with-click text_with_click_string: Specifies to block advertisements. Mobile client users will see a placeholder frame instead of each blocked advertisement. Each placeholder frame contains the text specified here along with the advertisement’s URL. To view the blocked advertisements users must click the placeholder frames.
|
text_with_click_string must be an alpha and/or numeric string of 1 through 255 characters in length.
params { ad-filter display bgcolor bg_color_code | compression level compression_level | url-rewrite prefix url_rewrite_prefix }
|
•
|
ad-filter display bgcolor bg_color_code: For the HTTP Advertisement Filter feature, specifies color code for the advertisement placeholder frames’ background.
|
bg_color_code must be a hex string of 1 through 6 characters in length.
|
•
|
compression level compression_level: Enables HTTP compression, and specifies the compression level.
|
compression_level specifies the HTTP compression level, and must be an integer from 1 through 9. The higher the compression_level, the better the compression but more the CPU and memory utilization.
|
•
|
url-rewrite prefix url_rewrite_prefix: Enables HTTP URL rewrite, and specifies the HTTP URL rewrite prefix.
|
url_rewrite_prefix specifies the HTTP URL rewrite prefix, and must be an alpha and/or numeric string of 8 through 32 characters in length.
The URLs that are embedded in response pages are rewritten. This eliminates the need for the subscriber to perform DNS to resolve those URLs. See the url-rewrite option.
Default: continue-tpo
Important: In this release, only TPO TCP optimizations are disabled. Disabling HTTP optimizations will be supported in a future release.tcp { bandwidth { bandwidth_kbps | dynamic } | buffer-size { downlink | uplink } buffer_size_kb | congestion-control { basic | vegas | westwood-plus } | fast-retransmit-dupacks { duplicate_acks | dynamic } | handoff-optimization | initial-window { initial_window | dynamic bdp-percent bdp_percent | rfc5681 } | mss mss | pacing | rto { retrans-backoff { 1.0 | 1.5 | 2.0 } | rttvar-scaling scaling_factor } }

|
bandwidth_kbps specifies the maximum available bandwidth for a TCP flow, in kbps, and must be an integer from 1 through 100000.
|
|
•
|
dynamic specifies to use a value computed dynamically at runtime.
|
Default: No known bandwidth limit, same as no tcp bandwidth command.
buffer-size { downlink | uplink } buffer_size_kb
|
•
|
downlink: Specifies the maximum amount of data that can be buffered inside TCP Proxy in downlink direction for each TCP connection. When the amount of data buffered in TCP Proxy in downlink direction reaches this limit, TCP Proxy sets receive window size in TCP header to 0 towards TCP server.
|
|
•
|
uplink: Specifies the maximum amount of data that can be buffered inside TCP Proxy in uplink direction for each TCP connection. When the amount of data buffered in TCP Proxy in uplink direction reaches this limit, TCP Proxy sets receive window size in TCP header to 0 towards TCP client.
|
buffer_size_kb specifies the buffer size, in KB, and must be an integer from 4 through 8192.
|
•
|
basic: Specifies to use the basic TCP congestion-control algorithm.
|
|
•
|
vegas: Specifies to use the Vegas TCP congestion-control algorithm.
|
|
•
|
westwood-plus: Specifies to use the Westwood-plus TCP congestion-control algorithm.
|
Default: basic
|
•
|
duplicate_acks: Specifies the number of duplicate ACKs that will trigger a fast-retransmit of the missing segment. After the specified number of duplicate ACKs is received, it is assumed that the segment was lost and is retransmitted.
|
duplicate_acks must be an integer from 1 through 10.
|
•
|
If the dynamic keyword is not configured, D-SACK detection takes place, but no action is taken.
Important: In case the client does not support SACK, the behavior falls back to as described for 12.0 and earlier releases. For information on D-SACK Support, refer to the Traffic Performance Optimization Administration Guide.
|
•
|
initial_window: Specifies the initial-window in units of MSS segments.
|
initial_window must be an integer from 1 through 255.
|
•
|
dynamic bdp-percent bdp_percent: Specifies to use a dynamically computed value at runtime, which is calculated as a percentage of bandwidth-delay product (BDP).
|
bdp_percent must be an integer from 1 through 100.
For dynamic setting, the bandwidth information is derived from the bandwidth command, and the delay is calculated using the SYN-ACK exchange. If the bandwidth information is not available, this configuration does not have any effect (i.e., behavior will be same as default setting).
|
•
|
rfc5681: Specifies to use a value recommended by RFC 5681, which will vary from 2 through 4 based on MSS.
|
Default: rfc5681
mss mss
mss must be an integer from 248 through 65535.
|
•
|
1.0: Specifies to use backoff factor 1.0.
|
|
•
|
1.5: Specifies to use backoff factor 1.5.
|
|
•
|
2.0: Specifies to use backoff factor 2.0.
|
|
•
|
rttvar-scaling scaling_factor
|
scaling_factor must be an integer from 0 through 4.
