NTP Servers and Time Zone
Having the different VSP elements time synchronized with NTP is essential to ensure that the
messages passed between the VSD, HP VSC and VRS elements are appropriately timestamped
to ensure proper processing.
Specify one or more (and preferrably three) NTP servers should be defined like in the example
below (10.0.0.123, 10.10.10.18 and 10.200.223.10).
The time zone is set with the zone command (PST) with the daylight savings time zone set with
the dst-zone command (PDT). The dst-zone will automatically complete the start and end dates
and times, but can be edited if needed.

XMPP and OpenFlow
Specify the xmpp server (xmpp.example.com) and username (NSC-vPE-1) and password
(password). The ejabberd server is configured to auto-create the user on the server with the
supplied username and password.
For OpenFlow, optional subnets can be specified with the auto-peer command which restricts
inbound OpenFlow connections from that subnet. If no auto-peer stanza is configured,
OpenFlow will sessions will be accepted on all interfaces, both in-band and out-of-band.
