Serial1

Interface through which the serial connection is taking place.

HDLC

The serial connection is an HDLC connection.

myseq 636119

The myseq counter increases by one each time the router sends a keepalive packet to the remote router.

mineseen 636119

The value of the mineseen counter reflects the last myseq sequence number the remote router has acknowledged receiving from the router. The remote router stores this value in its yourseen counter and sends that value in a keepalive packet to the router.

yourseen 515032

The yourseen counter reflects the value of the myseq sequence number the router has received in a keepalive packet from the remote router.

line up

The connection between the routers is maintained. Value changes to "line down" if the values of the myseq and myseen fields in a keepalive packet differ by more than three. Value returns to "line up" when the interface is reset. If the line is in loopback mode, ("looped") appears after this field.

Illegal serial link type code xxx, PC = 0xnnnnnn

This message is displayed if the router attempts to send a packet containing an unknown packet type.

Illegal HDLC serial type code xxx, PC = 0xnnnnn

This message is displayed if an unknown packet type is received.

Serial 0: attempting to restart

This message is displayed periodically if the interface is down. The hardware is then reset to hopefully correct the problem.

Serial 0: Received bridge packet sent to nnnnnnnnn

This message is displayed if a bridge packet is received over a serial interface configured for HDLC, and bridging is not configured on that interface.

BRI: D-chan collision

A collision on the ISDN D-channel has occurred; the software will retry transmission.

Received SID Loss of Frame Alignment int.

The ISDN hardware has lost frame alignment. This usually indicates a problem with the ISDN network.

Any of these messages can be displayed when a receive error occurs on one of the ISDN channels. The (d) indicates which channel it is on. These messages can indicate a problem with the ISDN network connection.

BRI0: Reset from 0xnnnnnnn

The BRI hardware has been reset. The 0xnnnnnnn variable is the address of the routine that requested that the hardware be reset; it is useful only to development engineers.

BRI(d): Bad state in SCMs scm1 = x scm2 = x scm3 = x

BRI(d): Bad state in SCONs scon1 = x scon2 = x scon3 = x

BRI(d): Bad state ub SCR; SCR = x

Any of these messages can be displayed if the ISDN hardware is not in the proper state. The hardware is then reset. If the message is displayed constantly, it usually indicates a hardware problem.

BRI(d): Illegal packet encapsulation = n

This message is displayed if a packet is received, but the encapsulation used for the packet is not recognized. It can indicate that the interface is misconfigured.

MK5(d): Reset from 0xnnnnnnnn

This message indicates that the hardware has been reset. The 0xnnnnnnn variable is the address of the routine that requested that the hardware be reset; it is useful only to development engineers.

MK5(d): Illegal packet encapsulation = n

This message is displayed if a packet is received, but the encapsulation used for the packet is not recognized. Possibly an indication that the interface is misconfigured.

MK5(d): No packet available for packet realignment

This message is displayed in cases where the serial driver attempted to get a buffer (memory) and was unable to do so.

MK5(d): Bad state in CSR0 = (x)

This message is displayed if the hardware is not in the proper state. The hardware is then reset. If this message is displayed constantly, it usually indicates a hardware problem.

MK5(d): New serial state = n

This message is displayed to indicate that the hardware has interrupted the software. It displays the state that the hardware is reporting.

MK5(d): DCD is down.

MK5(d): DCD is up.

If the interrupt indicates that the state of carrier has changed, one of these messages is displayed to indicate the current state of DCD.
