Configuration Limiting
The Cisco IOS XR software places preset limits on the configurations you can apply to the running
configuration of a router. These limits ensure that the router has sufficient system resources (such as
RAM) for normal operations. Under most conditions, these preset limits are sufficient.
In some cases, where a large number of configurations is wildcard required for a particular feature, it
may be necessary to override the preset configuration limits. This override can be done only if
configurations for another feature are low or unused. For example, if a router requires a large number of
BGP configurations, and Multiprotocol Label Switching (MPLS) is not being used at all, then the BGP
limits can be increased to use the unused memory assigned to MPLS.
Caution Overriding the default configuration limits can result in a low-memory condition.
Step 4
group group-name
Example:
RP/0/RP0/CPU0:router(config-un)# group sysadmin
Assigns the user named in Step 2 to a user group.
• The user takes on all the attributes of the user group, as
defined by the user group association to various task
groups.
• Each user must be assigned to at least one user group.
A user may belong to multiple user groups.
Step 5
Repeat Step 4 for each user group to be associated with
the user specified in Step 2.

Step 6
end
or
commit
Example:
RP/0/RP0/CPU0:router(config-un)# end
or
RP/0/RP0/CPU0:router(config-un)# commit
Saves configuration changes.
• When you issue the end command, the system prompts
you to commit changes:
Uncommitted changes found. Commit them?
– Entering yes saves configuration changes to the
running configuration file, exits the configuration
session, and returns the router to EXEC mode.
– Entering no exits the configuration session and
returns the router to EXEC mode without
committing the configuration changes.
• Use the commit command to save the configuration
changes to the running configuration file and remain
within the configuration session.
