DRA-2 UNIVERSAL COMMUNICATION NODE

USER GUIDE - Rev.5 (January 2018)
equipment determines the presence or absence of level 2 switching equipment
connected to the interface. This is useful in cases in which the type of equipment to
be connected is not known, but the processing of traffic is slowed down.
Even when the
Edge
parameter is
on
, the switch maintains activated the detection
of other switch connection to the interface, so operating state can become
off
.
The operating mode of the interface can be checked in the STP statistics section.
•
PtP.
The PtP parameter establishes whether the interface is directly connected to
other level 2 switching equipment on an end-to-end link (
on
value) or not (
off
value) but the equipment is also capable of detecting that situation (
auto
value). If
the equipment indicates that a link is PtP, this allows greater speed in protocol
convergence, and the agreement process on changing the state of a link from
designated
to
non-discarding (
operative for user traffic) is speeded up.
•
Edge Tx Filter.
When the RSTP protocol is executed, this parameter allows the
user to enable a filter that avoids the transmission of STP BPDU packets in the
interfaces operating in
edge
mode. This parameter is only effective when the
operating state of the interface is
edge
, and this situation is only possible when the
Edge
parameter is configured as
on
or
auto
.
Switch interconnection using interfaces
with
Edge_Tx_filter active
lead to
switches
being unable to detect
the connection as part of a loop.

NTP CONFIGURATION
The equipment has an NTP client, meaning that it can synchronise time-related information
by accessing NTP servers. The NTP [5] protocol is a standard that is widely used in
TCP/IP-based networks. It admits the use of several NTP servers simultaneously, and the
option of using authentication.
