Configuring Always On Service
Always On service maintains the subscriber’s packet data session in the local network. The PDSN will
not initiate release of the subscriber’s packet data session due to PPP idle timer expiry, unless the PDSN
determines the user is no longer reachable. The Always On feature is enabled by default. To change the
default parameters related to this feature, use following command:
Router(config)# cdma pdsn failure-history entries
Specifies the maximum number of entries that can
be maintained in the SNMP session failure table.
Router(config)#no virtual-template snmp
Prevents the virtual-access subinterfaces from
being registered with the SNMP functionality of
the router and reduces the amount of memory
being used, thereby increasing the call setup
performance.
Command Purpose
Command Purpose
Router(config)# cdma pdsn a10 always-on keepalive {interval
1-65535 [attempts 0-255] | attempts 0-255}
Configures always-on service parameters on the
PDSN.
The keepalive interval is the duration in seconds,
for which the PDSN waits for the LCP echo
response from peer before sending next LCP echo.
The default value is 3seconds. The no form of this
command will return to the default value.
attempts is the number of times LCP echo must be
sent before declaring an always-on user is not
reachable for tearing down the session after the
idle timer expires. The default value is 3.
Configuring this variable to 0 is similar to
ignoring the always-on property for the user.
