The CLI command show isa video-group video-group-id displays the peak egress bandwidth and sessions per ISA. Each peak value is also marked with a timestamp.
There are configurable watermarks for bandwidth and session consumption. The watermarks generate SNMP traps or log events when the ISA has reached the bandwidth or session thresholds. The egress bandwidth and session watermarks are configurable for FCC and RET separately, and also for FCC and RET together. The SNMP trap or log event is generated as the configured watermark is exceeded and is cleared if it falls below 10% of the watermark. For example, if the maximum egress rate is 10 Gb/s and the watermark is set at 90%, the alarm is generated when the egress rate exceeds 9 Gb/s (90% of 10 Gb/s) and the alarm is cleared if the egress rate falls below 10% at 8.1 Gb/s (10% of 9 Gb/s = 0.9 Gb/s, and 9 Gb/s - 0.9 Gb/s = 8.1 Gb/s).
