HAPTER 10: PACKET OVER SONET ADMINISTRATION
Enabling NCP
IP Control Protocol (IPCP) is the Network Control Protocol (NCP) used to
configure, enable, and disable IP protocol access on both ends of a SONET
point-to-point circuit. In order for IP packets to be transmitted over the
point-to-point link, IPCP must reach the open state. This enables IP
communication between the two circuit endpoints.
By default, the Cuda 12000 is configured to provide its IP address during
IPCP negotiations. But when negotiating with a Juniper Networks system,
providing the IP address during IPCP negotiation prevents a successful
connection.
When the interface must connect with a Juniper Networks system, you can
disable reporting of an IP address during IPCP negotiation. To enable or
disable reporting of the IP address during negotiation, follow this procedure:
1. In the Summary window, select the interface that you wish to configure.
2. Click the NCP tab.
3. Enable or disable reporting of the IP address during IPCP negotiation by
selecting the Report Local IP Address During Negotiation option. When
Bad FCS’s Number of received packets that have been discarded
due to having an incorrect FCS.
Local Maximum
Receive Unit (MRU)
Current value of the MRU for the local PPP Entity. The
remote entity uses this MRU when sending packets to
the local PPP entity. Value is meaningful only when the
link has reached the open state
Remote Maximum
Receive Unit (MRU)
Current value of the MRU for the remote PPP Entity. The
interface uses this MRU when sending packets to the
remote PPP entity. Value is only meaningful when the
link has reached the open state.
Transmit FCS Size
(bits)
Frame Check Sequence (FCS) in bits that the local entity
generates when sending packets to the remote entity.
Value is only meaningful when the link has reached the
open state.
Receive FCS Size
(bits)
Size of the Frame Check Sequence (FCS) in bits that the
remote entity generates when sending packets to the
local entity. Value is only meaningful when the link has
reached the open state.
