PPP Options
Synchronous connections use an encapsulation protocol such as PPP to deliver packets from
one box to another. PPP sessions are single-channel connections to any remote device running
PPP software. Following are the Answer > PPP Options parameters that define what type of
routing or bridging protocol is supported over a PPP connection:
Parameter
Route IP
Route IPX
Route AppleTalk
Bridge
Foundation parameters
The following Answer > PPP Options parameters define the foundation for the PPP session:
Parameter
Recv Auth
MRU
LQM
LQM Min
LQM Max
Link Comp
VJ Comp
CBCP Enable
MAX 6000/3000 Network Configuration Guide
Configuring Individual WAN Connections
Specifies
Routing of IP data packets on the interface. IP routing must be enabled
on both sides of the connection, and the MAX unit must be configured
with an IP address in the Ethernet profile. To establish an inbound
connection, IP routing must also be enabled in the Answer profile.
Routing of IPX data packets on the interface. IPX routing must be
enabled on both sides of the connection, and the unit must be
configured with an IPX network address and frame type in the
Ethernet profile. Note that the unit routes and spoofs only one IPX
frame type. Other frame types will be bridged if bridging is enabled.
Routing of AppleTalk data packets on the interface. AppleTalk routing
must be set on both sides of the connection.
Link-level bridging. The unit bridges frames on the basis of the
frame's destination MAC address.
Specifies
Authentication protocol the MAX unit uses to receive and verify a
password for an incoming PPP connection.
Maximum number of bytes the unit can receive in a single frame.
Usually the default is the right setting, unless the far end requires a
lower number.
Whether or not the unit requests Link Quality Monitoring (LQM)
when answering a PPP call.
Minimum duration between link-quality reports for PPP connections,
measured in 10ths of a second.
Maximum duration between link-quality reports for PPP connections,
measured in 10ths of a second.
Link compression method for a PPP, MP, and MP+ call. Both sides of
the connection must set the same type of link compression.
Whether or not Van Jacobson IP header compression should be
negotiated on incoming calls using encapsulation protocols that
support this feature.
How the unit responds to caller requests to support Callback Control
Protocol (CBCP). Microsoft's CBCP is a Link Control Protocol (LCP)
option negotiated at the beginning of PPP sessions. CBCP
authenticates a caller by means of a user name and password.
