Setting Resource Thresholds
Page 11-5
CAM Threshold (MPM/HRE or NI)
The CAM threshold sets a percentage of the total amount of space available for storing the
cache tables. Cache tables maintain associations between received MAC addresses and the
ports they were received on. For the switch level, the CAM threshold separately monitors the
MPX and the HRE-X daughtercard (if it is installed) CAM tables. For the module level, it moni-
tors the switching module CAM tables. CAM thresholds are not available on the port level.
When this percentage is exceeded, an SNMP trap is sent.
CPU Threshold
The CPU threshold sets a percentage of the total amount of processing ability for the MPX.
When the CPU usage exceeds this percentage, an SNMP trap is sent. The CPU threshold is only
used for the switch level.
Memory Threshold
The memory threshold sets a percentage of the total amount to MPX RAM memory for the
switch. When RAM usage exceeds this percentage, an SNMP trap is sent. The memory thresh-
old is only used for the switch level.
VCC Threshold
This value is a number set as a percent. VCC Threshold is equal to the total number of active
VCCs divided by the switch VCC capacity. When this value is exceeded, an SNMP trap is sent.
Temperature Threshold
This threshold sets the number of degrees for the switch at which an SNMP trap is sent. This
threshold is measured in degrees Celsius. The range is from 0 to 100.
Virtual Port Threshold
This threshold sets a percentage of the total number of available virtual ports for the switch.
When the set percentage of available virtual ports is exceeded, an SNMP trap is sent.
