IBR will avoid synchronizing to a server whose time might not have been synchronized or to
one whose time is significantly different than the time from other associated servers, even if
its stratum is lower.
When NTP is enabled on IBR, NTP time will take precedence over time provided by any other
source or method.
7.9 System Message Logging
IBR sends the output of system messages and certain Privileged commands to a logging
process that can be configured to distribute such messages to a logging file, remote syslog
server, or operator’s console. Detailed instructions for configuring message logging are
contained in the CLI Guide.
7.10 Quality of Service (QoS) & Class of Service (CoS)
IBR supports QoS packet prioritization in compliance with IEEE 802.p. By default, QoS is
disabled and must be configured and enabled by an operator using the commands and
procedures described in this section.
IBR’s CLI has commands that allow an operator to create and configure Traffic Classes and
Traffic Policies that are associated with specified IBR interfaces. The CLI Guide contains
detailed information for configuring QoS/CoS features.
