I am using a PCI card, I configured it this way in my kernel called ZEBRA: "device sr0 at pci? port 0x300 irq 3 iomem 0xd0000" "pseudo-device sppp" The irq 3 is unique, it is not used by any other device in this kernel. > 2.

NETGRAPH does not exist in this kernel, therfore I specified "encaps ppp" on the cisco config, and it also provides a clock of 2 Mhz. > > sr1: Down event, taking interface down. > > ... > > sr1: Down event, taking interface down. > > sr1: Down event, taking interface down. > > sr1: lcp illegal conf-req in state initial > > ... > > sr1: lcp illegal conf-req in state initial > > sr1: lcp illegal conf-req in state initial > > This is a bug in the state machine of sppp. I have fixed it in -current, > but haven't merged it into stable yet.

From this debug information, I think that we can see that the card does not receive the clock signal from the cisco. When we see that "magic 0x54ef40a0", does it correspond to what we call magic number ? sr0: lcp close(initial) sr0: lcp open(initial) sr0: phase establish sr0: lcp up(starting) sr0: lcp output <conf-req id=0x1f len=10 05-06-7d-be-bb-d1> sr0: lcp TO(req-sent) rst_counter = 10 sr0: lcp output <conf-req id=0x20 len=10 05-06-7d-be-bb-d1> sr0: lcp TO(req-sent) rst_counter = 9 sr0: lcp output <conf-req id=0x21 len=10 05-06-7d-be-bb-d1> sr0: lcp TO(req-sent) rst_counter = 8 sr0: lcp output <conf-req id=0x22 len=10 05-06-7d-be-bb-d1> sr0: lcp TO(req-sent) rst_counter = 7 sr0: lcp output <conf-req id=0x23 len=10 05-06-7d-be-bb-d1> sr0: lcp TO(req-sent) rst_counter = 6 sr0: lcp output <conf-req id=0x24 len=10 05-06-7d-be-bb-d1> sr0: lcp TO(req-sent) rst_counter = 5 sr0: lcp output <conf-req id=0x25 len=10 05-06-7d-be-bb-d1> sr0: lcp input(req-sent): <conf-req id=0x2d len=10 05-06-54-ef-40-a0> sr0: lcp parse opts: magic sr0: lcp parse opt values: magic 0x54ef40a0 send conf-ack sr0: lcp output <conf-ack id=0x2d len=10 05-06-54-ef-40-a0> sr0: lcp input(ack-sent): <conf-req id=0x2e len=10 05-06-54-ef-40-a0> sr0: lcp parse opts: magic sr0: lcp parse opt values: magic 0x54ef40a0 send conf-ack sr0: lcp output <conf-ack id=0x2e len=10 05-06-54-ef-40-a0> sr0: lcp input(ack-sent): <conf-req id=0x2f len=10 05-06-54-ef-40-a0> sr0: lcp parse opts: magic sr0: lcp parse opt values: magic 0x54ef40a0 send conf-ack sr0: lcp output <conf-ack id=0x2f len=10 05-06-54-ef-40-a0> sr0: lcp input(ack-sent): <conf-req id=0x30 len=10 05-06-54-ef-40-a0> sr0: lcp parse opts: magic sr0: lcp parse opt values: magic 0x54ef40a0 send conf-ack sr0: lcp output <conf-ack id=0x30 len=10 05-06-54-ef-40-a0> sr0: lcp input(ack-sent): <conf-req id=0x31 len=10 05-06-54-ef-40-a0> sr0: lcp parse opts: magic sr0: lcp parse opt values: magic 0x54ef40a0 send conf-ack sr0: lcp output <conf-ack id=0x31 len=10 05-06-54-ef-40-a0> sr0: lcp input(ack-sent): <conf-req id=0x32 len=10 05-06-54-ef-40-a0> sr0: lcp parse opts: magic sr0: lcp parse opt values: magic 0x54ef40a0 send conf-ack sr0: lcp output <conf-ack id=0x32 len=10 05-06-54-ef-40-a0> sr0: lcp input(ack-sent): <conf-req id=0x33 len=10 05-06-54-ef-40-a0> sr0: lcp parse opts: magic sr0: lcp parse opt values: magic 0x54ef40a0 send conf-ack sr0: lcp output <conf-ack id=0x33 len=10 05-06-54-ef-40-a0> sr0: lcp input(ack-sent): <conf-req id=0x34 len=10 05-06-54-ef-40-a0> sr0: lcp parse opts: magic sr0: lcp parse opt values: magic 0x54ef40a0 send conf-ack sr0: lcp output <conf-ack id=0x34 len=10 05-06-54-ef-40-a0> sr0: lcp input(ack-sent): <conf-req id=0x35 len=10 05-06-54-ef-40-a0> sr0: lcp parse opts: magic sr0: lcp parse opt values: magic 0x54ef40a0 send conf-ack sr0: lcp output <conf-ack id=0x35 len=10 05-06-54-ef-40-a0> sr0: lcp input(ack-sent): <conf-req id=0x36 len=10 05-06-54-ef-40-a0> sr0: lcp parse opts: magic sr0: lcp parse opt values: magic 0x54ef40a0 send conf-ack sr0: lcp output <conf-ack id=0x36 len=10 05-06-54-ef-40-a0> sr0: lcp input(ack-sent): <conf-req id=0x37 len=10 05-06-54-ef-40-a0> sr0: lcp parse opts: magic sr0: lcp parse opt values: magic 0x54ef40a0 send conf-ack sr0: lcp output <conf-ack id=0x37 len=10 05-06-54-ef-40-a0> sr0: lcp TO(ack-sent) rst_counter = 4 sr0: lcp output <conf-req id=0x26 len=10 05-06-7d-be-bb-d1> sr0: lcp TO(ack-sent) rst_counter = 3 sr0: lcp output <conf-req id=0x27 len=10 05-06-7d-be-bb-d1> sr0: lcp TO(ack-sent) rst_counter = 2 sr0: lcp output <conf-req id=0x28 len=10 05-06-7d-be-bb-d1> sr0: lcp TO(ack-sent) rst_counter = 1 sr0: lcp output <conf-req id=0x29 len=10 05-06-7d-be-bb-d1> sr0: lcp TO(ack-sent) rst_counter = 0 sr0: phase dead sr0: lcp down(stopped) sr0: phase establish sr0: lcp up(starting) sr0: lcp output <conf-req id=0x2a len=10 05-06-7d-be-bb-d1> sr0: Down event, taking interface down. sr0: lcp close(req-sent) sr0: lcp output <term-req id=0x2b len=4> sr0: lcp TO(closing) rst_counter = 2 sr0: lcp output <term-req id=0x2c len=4> sr0: lcp TO(closing) rst_counter = 1 sr0: lcp output <term-req id=0x2d len=4> sr0: lcp TO(closing) rst_counter = 0 sr0: phase dead sr0: lcp down(closed) sr0: Down event, taking interface down.
