RoHC Profile Common Options Configuration Mode Commands


RoHC Profile Common Options Configuration Mode Commands
 
 
The RoHC Profile Common Options Configuration Mode is used to set timers that, upon expiration, release header compression contexts.
 
 
delay-release-hc-context-timer
Sets a delay in releasing RoHC contexts allowing for context continuation during intra-gateway handoffs.
Product
HSGW, PDSN
Privilege
Administrator
Syntax
delay-release-hc-context-timer seconds
no delay-release-hc-context-timer
no
Removes previously configured value for this command. No value disables the feature.
seconds
Specifies the number of seconds the system delays before releasing the header compression context. seconds must be an integer value from 0 to 65535.
Usage
Use this command to set a delay in releasing a header compression context. THis command is necessary when employing RoHC and mobility. Typically, when an RP connection is released, the header compression context is also released immediately. However, in mobility situations, such as intra-PDSN handoffs, the header compression context should be preserved. Adding a delay to cover the handoff time allows the context to be maintained.
A header compression context contains the compression/decompression configuration and statistics for the session.
Example
The following command sets the header compression release delay to 20 seconds:
delay-release-hc-context-timer 20
 
end
Exits the current mode and returns to the Exec Mode.
Product
All
Privilege
Security Administrator, Administrator
Syntax
end
Usage
Change the mode back to the Exec mode.
 
exit
Exits the current mode and returns to the previous mode.
Product
All
Privilege
Security Administrator, Administrator
Syntax
exit
Usage
Return to the previous mode.
 
inactive-traffic-release-hc-context-timer
Set an inactivity timer that is checked when inactivity is detected on an SO67 A10 bearer connection with negotiated RoHC parameters. If the inactivity continues to the end of the configured time, the header compression context is released.
Product
HSGW, PDSN
Privilege
Administrator
Syntax
inactive-traffic-release-hc-context-timer seconds
no inactive-traffic-release-hc-context-timer
no
Removes previously configured value for this command. No value disables the feature.
seconds
Specifies the time, in seconds, the system waits for activity on the bearer channel before releasing the header compression context. seconds must be an integer value from 1 to 65535.
Usage
Use this command to set a timer that is started upon detecting inactivity on the bearer channel. Upon expiry, the header compression context is released. Enable this feature to allow for efficient memory utilization.
Example
The following command sets the bearer channel inactivity timer to 60 seconds:
inactive-traffic-release-hc-context-timer 60
