Predefined MAPS groups (Continued) TABLE 16
Predefined group name Object type Description
ALL_TUNNEL_F_QOS QoS
SWITCH Switch Default group used for defining rules on parameters that are
global for the whole switch level, for example, security
violations or fabric health.
CHASSIS Chassis Default group used for defining rules on parameters that are
global for the whole chassis, for example, CPU or flash.
For more information on groups, refer to:
• MAPS groups overview on page 35
• User-defined groups on page 38
User-defined groups
User-defined groups allow you to specify groups defined by characteristics you select.
In many cases, you may need groups of elements that are more suited for your environment than the
predefined groups. For example, small form-factor pluggable (SFP) transceivers from a specific
vendor can have different specifications than SFP transceivers from another vendor. When monitoring
the transceivers, you may want to create a separate group of SFP transceivers for each vendor. In
another scenario, some ports may be more critical than others, and so can be monitored using
different thresholds than other ports.
You can define membership in a group either statically or dynamically. For a group using a static
definition, the membership is explicit and only changes if you redefine the group. For a group using a
dynamic definition, membership is determined by meeting a filter value. When the value is met, the
port or device is added to the group, and is included in any monitoring. When the value is not met, the
port or device is removed from the group, and is not included in any monitoring data for that group.
The following items should be kept in mind when working with user-defined groups:
• A port or device can be a member of multiple groups.
• A maximum of 64 user-defined groups and imported flows combined is permitted per logical switch.
• All operations on a dynamic group are similar to those for static groups.
• Dynamic groups can only be defined based on the port type.
• The device node WWN information is fetched from the FDMI database, allowing group membership
to be validated using it.
• On an Access Gateway device, if a group is created with the feature specified as “device node
WWN”, the ports on the switch that are connected to the Access Gateway are not taken into
account. However, on the Access Gateway itself, the ports where devices are connected will be part
of the group.
• Group names are not case sensitive; My_Group and my_group are considered to be the same.
Creating a static user-defined group
MAPS allows you to create a monitorable group defined using a static definition, in which the
membership is explicit and only changes if you redefine the group.
As an example of a static definition, you could define a group called MY_CRITICAL_PORTS and
specify its members as “2/1-10,2/15,3/1-20”. In this case, the group has a fixed membership, and to
