XSR User’s Guide A-1
A
Alarms/Events, System Limits,
and Standard ASCII Table
This appendix describes the configuration and memory limits of the XSR as well as system High,
Medium and Low severity, firewall and NAT (separately described on page A-14) alarms and
events captured by the router.
Recommended System Limits
The XSR suggests limits on the following configurable functions. These recommended limits are
not hard-coded, nor are they the Extreme Limits referenced in “Memory Management” on page 2-37,
but should serve as a guideline for purposes of memory carving.
