I have Cisco6513 with one IDSM-2 slot.
I faced the following issue:
Suddenly traffic over the network became very very slow. I troubleshoot the issue so I found that IPS1 LOAD reached 100%. So via CLI, I did the IPS1 in BYPASS mode ON. Then traffic came back to their normal position and all the network was started working fine. This issue has occurred many times. (But we never faced this issue before E3 Signature update).
Then after some time I OFF the BYPASS mode to its previous mode. Now network is again working normal.
I want to identify the issue behind this IPS LOAD behavior.
All signatures are in default state.
IPS1 version Detail:
Cisco Intrusion Prevention System, Version 6.1(2)E3
Signature Update S440.0
Cisco6513 IOS: Version 12.2(18)SXF17
