Some sample syslog messages are as follows:
2000 Jan 11 06:00:27 PST -07:00 %SYS-4-SYS_HITRFC: 62% traffic detected on switching bus
(A)
2000 Feb 21 12:00:27 PST -07:00 %SYS-4-SYS_HITRFC: 65% traffic detected on switching bus
Low Remaining Memory
When memory allocation of clusters and buffers on the Catalyst 6500 series switch goes above a high
watermark of 90 percent, the syslog messages are generated. These actions generate the syslog
messages:

A sample syslog message is as follows:
1999 Sep 9 00:00:00 PDT -07:00 %SYS-3-SYS_MEMLOW: Memory cluster usage exceeded 90%
1999 Sep 9 00:00:00 PDT -07:00 %SYS-3-SYS_MEMLOW: Mbuf usage exceeded 90%
1999 Sep 9 00:00:00 PDT -07:00 %SYS-3-SYS_MEMLOW: Malloc usage exceeded 90%
Detected Memory Corruption
By default, memory corruption that is detected by the Memory Management Module (MMU) is enabled.
This example shows how to enable memory corruption detection:
Console> (enable) set errordetection memory
Usage: set errordetection memory <enable|disable>
Console> (enable) set errordetection memory enable
Memory error detection enabled.

When cluster allocation usage goes above a high watermark of 90 percent, the throttle interval is
1 hour.
When mbufs allocation usage goes above a high watermark of 90 percent, the throttle interval is
1 hour.
When malloc allocation usage goes above a high watermark of 90 percent, the throttle interval is
1 hour.
