Deployment Guide

Rules based on the ALL_D_PORTS group are part of the default policies, and have error thresholds
spanning multiple time windows or bases. If any of the rules are triggered, MAPS triggers the action
configured for the rule, alerts the fabric service module if appropriate, and caches the data in the
dashboard.
The D_Port diagnostic output classifies the error conditions into the following states:
• Errors within operating range
• Errors outside of operating range
D_Port monitoring monitors all D_Port errors; however, the fabric service module is only notified for the
following errors:
• CRC
• ITW — enc_out+enc_in
• LF
• PE
• LOSS_SYNC
The D_Port monitoring feature is only supported for 10 Gbps and 16 Gbps SFPs and 8Gbps LWL and
ELWL ports on the following blades: CR16-4, CR16-8, FC8-32E, FC8-48E, FC16-32, FC16-48, and
FC16-64.
NOTE
In versions of Fabric OS prior to 7.1, MAPS monitored D_Ports using the NON_E_F_PORTS group, but
the default rules for this group did not provide the flexibility now available through the ALL_D_PORTS
group.
The mapsRule command accepts the ALL_D_PORTS group, which can be used as shown in the
following example.
mapsrule --create d_port_mon -group ALL_D_PORTS -monitor CRC -t min -op ge -value 1 -
action raslog -policy nil
