sessmgr_instance_number } [ verbose ] | summary } [ | { grep grep_options | more } ]
sessmgr { all | instance sessmgr_instance_number } [ verbose ]
Displays information for all or the specified Session Manager (SessMgr) instance.
all
: Displays information for all SessMgr instances.
instance sessmgr_instance_number
: Displays information for a SessMgr instance specified as
an integer from 1 through 65535.
verbose
: Displays detailed statistics for specified criteria. Use this keyword to view the learnt IP
addresses.

Usage
Use this command to view statistics for the DNS Snooping feature related DNS learnt-ip-addresses.
This command displays the number of learnt IP entries per rule line. It displays on a service level the number
of resolved (learnt) IP addresses per rule line per rulebase (once if a rule line is used multiple times in the
same rulebase as it is shared across rulebase) per destination context per SessMgr instance. It also displays
the number of entries flushed due to TTL expiry. The field entries_replaced gives the number of entries
replaced (same IP returned again) in the pool due to a DNS response by same/another subscriber for same
domain-name, wherein the TTL of the entry will be replaced.
IPv4-overflows will start incrementing when the maximum limit of 51200 across system is reached OR limit
of 200 per pattern is reached.
