3.1.2 Matrix Server Administration Guide

Appendix B: Error and Log File Messages 279

Interface <ethn> has gone down after an attempt to assign an

outbound multicast interface: <No such device>

Interface <eth_n> has been marked down because its interface

flags do not include IFF_UP

If PanPulse determines that the interfaces are down or unavailable on

another server, it will report the following:

No interfaces are responding on host <xxx.xxx.xxx.xxx>

PanPulse should receive matrix traffic at certain intervals on the active

administrative network interface. If PanPulse does not receive any traffic

during this period of time, it will report the following message:

No traffic received on active panpulse interface (<ethn>)

PanPulse then fails over the active interface to another network interface

and reports the following. (You will also see this message for other

situations in which PanPulse chooses a new active interface.)

Selected new active interface <ethn> address

<xxx.xxx.xxx.xxx>

If PanPulse cannot communicate with all other active servers over a new

interface, it will report the following message:

Unable to fail over to another interface

Network Interface Requirements Are Not Met

PanPulse generates error messages when the requirements for a network

interface are not met.

Flags

Matrix Server requires that the following flags be set on network

interfaces used in a matrix:

UP, RUNNING, BROADCAST, MULTICAST. If any

of these flags are not set, you will see one of the following messages. The

ifconfig(8) man page describes how to set the required flags.

panpulse cannot use interface <ethn> because the required

interface flags (UP, RUNNING, BROADCAST, MULTICAST) are not

set. See ifconfig(8).
