Ipv6-overflows will start incrementing when maximum limit of 25600 across system is reached OR limit of
100 per pattern is reached.
Limits are:
100 per pattern is reached.
Limits are:
Maximum of 51,200 IPv4 entries per instance shared across IPv4 all pools.
Maximum of 200 IPv4 entries per pool (pool is same as discussed before (per rule-line pattern)).
Maximum of 25,600 IPv6 entries per instance shared across all IPv6 pools.
Maximum of 100 IPv6 entries per pool.
In releases prior to 14.0, this CLI command
show active-charging dns-learnt-ip statistics
sessmgr all
displayed all the configured patterns and rulebase names for each of the pattern entry, even
though the pattern has not learnt any IP address. When a large number of DNS snooping ruledefs are
configured (configured as ip server-domain name under ruledef configuration), the memory allocated for
sending this information exceeded the message size limit for messenger calls and hence the crash was
observed.
To avoid the crash occuring, in 14.0 and later releases, the output of the CLI command
configured (configured as ip server-domain name under ruledef configuration), the memory allocated for
sending this information exceeded the message size limit for messenger calls and hence the crash was
observed.
To avoid the crash occuring, in 14.0 and later releases, the output of the CLI command
show active-
charging dns-learnt-ip statistics sessmgr all
is modified to display only the patterns for which
at least one IPv4/IPv6 address is learnt as all other information is available from the configuration. Also for
each of the patterns this CLI command will not be displaying rulebase name as it can be printed once.

Example
The following command displays summary statistics for DNS learnt IP addresses:
