QXFXO4/QXISDN4/QXE1T1/QXFXS24 Manual II: Administrator’s Guide
Disable CCP (Compression Control Protocol) negotiation -
this
option should only be selected if the peer system is not working
properly. For example, if it is not accepting the requests from the
PPPD (Point-to-Point Daemon) for CCP negotiation.
Disable magic number negotiation -
with this option, PPPD
cannot detect a looped-back line. This option should only be
selected if the peer is not working properly.
Disable protocol field compression negotiation in both the
receive and the transmit direction –
with this option,
no
protocol field compression will take place.
Disable Van Jacobson style TCP/IP header compression in
both the transmit and the receive direction –
with this option,
no negotiation of TCP/IP header compression will take place and
the header will always be sent uncompressed.
Disable the connection-ID compression option in Van
Jacobson style TCP/IP header compression -
with this option,
PPPD will not compress the connection-ID byte from Van Jacobson
and will not ask the peer to do so.

Disable the IPXCP and IPX protocols -
this option should only be selected if the peer is not working properly and cannot handle requests from PPPD for
IPXCP negotiation.
SNMP Settings
The
Simple Network Management Protocol
(SNMP) is an application layer protocol that facilitates the exchange of management information between
network devices and is used by network administrators to manage network performance, find and solve network problems, and plan for network growth.
On QX gateway, SNMP agent is running to allow administrators to remotely manage QX gateway’s network and the device’s configuration. Remote
administration is being performed by means of special SNMP monitoring programs (SNMP Manager), which can automatically feedback by the certainly
configured actions on some events on the QX gateway or remotely modify QX gateway’s settings.
SNMP Settings
page is divided into two pages:
Global SNMP Settings
and
SNMP Trap Settings
.
Global SNMP Settings
are used to enable the SNMP
agent on the QX IP PBX, to select the SNMP protocol version for communication with the administrating application and to define the community for
administrating application to connect the QX gateway.
Global SNMP Settings
Enable SNMP
checkbox is used to enable SNMP agent on the QX gateway.
System Location
text field requires optional information to describe the network where SNMP management is performed.
System Contact
text field requires optional information about the
contact person responsible for the SNMP management in the
defined network. Field may indicate the point person’s name,
email address, phone number or other contact information.
Enable SNMP v1 / 2c
checkbox is used to enable SNMP v1/2c
protocol version for the messaging between QX gateways SNMP
agent and the administrating application. If this checkbox is not
selected,
SNMP v1
will be implied.
SNMP v1 / v2c Read-Only Community
text field is used to insert
the community description (public, private, etc.) for the read-only
management (like gathering information (events, statistics, etc.)
about QX gateway’s). Field may contain some kind of password
which should be matching both on QX gateway and on the
administrating application for successful SNMP management.
Enable SNMP v1 / 2c Read-Write Access
checkbox additionally
enables a read-write access on the QX gateway for the SNMP
monitoring application. With this checkbox enabled, administrator
will be able to remotely configure the QX gateway via SNMP
administrating program.
Fig.II- 140: Global SNMP Settings page
SNMP v1 / v2c Read-Write Community
text field is used to insert the community description (public, private, etc.) for the read-write management (like
gathering information (events, statistics, etc.) about QX gateway’s and remotely changing QX gateway’s configuration). Field may contain some kind of
password which should be matching both on QX gateway and on the administrating application for successful SNMP management.
The
Service Restart
button restarts the SNMP sub-system on the QX gateway. Restarting the SNMP sub-system is recommended if it does not respond to a
SNMP manager's requests.
