Rx packet Inactivity timeout (s):
This parameter specifies the amount of time the unit will wait without receiving any PPP pack-
ets before disconnecting. An inactivity timeout reset with each received PPP packet. The other
inactiv ity timer is reset by outgoing packets. When Detach GPRS between connection attempts
is set to “Yes”, the GPRS module will then detach and reattach.
Minimum link up-time (s):
If this parameter is set to a non-zero value, then PPP will not close the connection for the
specified period (in seconds), even if the link is inactive.
Maximum link up-time (s):
This parameter specifies the maximum time that this PPP may remain connected during any one
session. After this time, the PPP is deactivated.
Maximum negotiation time (s):
This parameter specifies the maximum time (in seconds) allowed for a PPP negotiation to
complete. If negotiations have not completed within this time after initial connection, the PPP is
disconnected.
Firewall:
The Firewall parameter is used to turn Firewall script processing “On” or “Off” for this inter-
face.
IGMP:
This IGMP parameter is used to enable or disable the transmission and reception of IGMP pack-
ets on this interface. IGMP is used to advertise members of multicast groups. If IGMP is enabled,
and a member of a multicast group is discovered on this interface, multicast packets for this
group received on other interfaces will be sent out this interface.
IPSec:
The IPSec parameter is used to enable or disable IPSec processing on this interface. If set to
“On”, packets sent or received on this interface must pass through the IPSec code before being
transmitted. IPSec may drop the packet, pass it unchanged, or encrypt and encapsulate within an
IPSec packet.
GRE:
Note:
From firmware version 4955 this web option and corresponding CLI commands have been
removed. GRE tunnels should be configured from Configure > Tunnel (GRE)
This parameter enables GRE (Generic Routing Encapsulation) for this PPP instance. GRE is
a simple tunnelling protocol. For further details refer to RFC2784 and also the Configure >
IPSec > Eroutes section of this manual.
QOS:
This parameter is used to turn QOS “On” or “Off” for this PPP instance.
RIP version:
RIP (Routing Information Protocol), is used by routers to determine the best route to any
destina tion. There are several different versions that can be enabled or disabled using this
parameter. When RIP Version is set to “Off”, RIP is disable and no RIP packets transmitted
out this interface. When RIP Version is set to V1 or V2, the unit will transmit RIP version 1 or
2 packets respectively (version 2 packets are sent to the “ALL ROUTERS” multicast address.
(224.0.0.9). When RIP Ver sion is set to V1 Compat, the unit will transmit RIP version 2 packets
to the subnet broadcast address. This allows V1 capable routers to act upon these packets.
When RIP is enabled, RIP packets are transmitted when the eth instance first becomes active,
and at intervals specified by the RIP Interval parameter on the Configure > General page.
