Hi Support people,
I have been trialling IOS IPS on a number of Cisco ISRg2 routers and I have found that after enabling it the CPU jumps to 99% and I see packet drops (ingress) on the interface that IPS is applied.
Has anyone else successfully deployed IOS IPS? If yes what router/s have you used and what did you do to mitigate high CPU usage and packet drops?
Thank you in advance for all of your quick reply’s
