In this tidbit I will cover some ESA nice-to-know CLI commands & their purposes:
> status = view counters/gauges; counters are a total of various events in the system; gauges show current utilization of system resources
> status detail
> hoststatus = returns monitoring info about email ops relating to specific recipient;
> tophosts = list of top 20 recipient hosts in queue;
> rate = real-time monitoring about email ops
> hostrate = real-time monitoring info on specific mail host
> topin = shows a snapshot of remote hosts connecting to the ESA
> dnsstatus = counter displaying stats for DNS lookup/cache info
The following are a few ways to manage the email queue:
> deleterecipients = lets you manage the delivery queue & delete recipients if necessary
> bouncerecipients = hard bounce recipients waiting for delivery
> redirectrecipients = redirect messages in email delivery queue to another relay host
> showrecipients = view messages in email delivery queue;
> suspenddel = sets ESA into suspended delivery state
> resumedel = return to regular ops
> suspendlistener = ESA will not accept connections to specific port of the configured listener
> resumelistener = return listener to normal state
> resume = resumes delivery & receiving
> findevent = allows you to search mail logs for a particular message;
Managing interfaces from cli:
> etherconfig
Managing vlans:
> interfaceconfig
That wraps this tidbit up, Cheers!
