I have a need to change name servers as configured in each WAE. However after the changes are applied (via the all-devices group), and verified using 'show hosts' on each WAE, the WAE's are still attempting to use the old name server previously in use.
This is confirmed by a tcpdump on the old name server.
Is there a CLI command that can be restart name/lookup services on the WAE or is the only solution a reboot of each WAE? (A reboot fixes it - but I'd like to avoid a reboot if possible).
