Description
CPU Utilization
434539
In the NSM Device Monitor > View Device Details > Process Status tab, the CPU usage for the IDP engine is
reported as 0%. To see the actual CPU usage for an IDP engine, log into the IDP Series device command-line
interface (CLI) and use the
(single-core platforms). The correct CPU usage is also reported via SNMP.
Stability
430363
IDP8200 stops processing traffic at high load with SYN protection enabled.
499447
For single core platforms (IDP75, IDP200, IDP600), we recommend you disable application volume tracking
(AVT). AVT processes are CPU intensive, resulting in link flapping under stress.
Note that if you disable AVT, IDP Reporter application volume reports are empty.
573031
Low memory triggered JNET bypass on IDP800.
Expected Behavior
547354
Packet drops are possible in simulation mode if the JNET free packet buffer is 0.
