Subject: Increase the default poll duration for Cisco n1kv
X-Git-Url: https://review.fuel-infra.org/gitweb?a=commitdiff_plain;h=6e08e477a9cb46b1d371c2c9812e5ce9f4cf69be;p=openstack-build%2Fneutron-build.git

Increase the default poll duration for Cisco n1kv

Increase the poll duration for Cisco N1Kv, from 10s to 60s and also
clean up the /etc/neutron/plugins/cisco/cisco_plugins.ini file. The
current poll duration of 10s causes that VSM to unnecessarily taking
frequent CPU cycles, resulting in the failure of other tasks in scale
configurations.

Closes-Bug: 1357030
