We have two IDSM-2's in seperate Cat6 chassis. Each IDSM-2 misses approx 48 pc of traffic.
The sensor's are set in promisc mode, and currently monitor 12 vlan's at an average rate of 180 mps thorughput. This rate has been monitored via PRTG. Cisco advised for us to upgrade to the latest software versions but the problem persists. If we reset the modules then the problem goes away for about 1 hr.
Anyone got any ideas. I am thinking RMA, but am confused that it is doing it on both blades.
For further information we have 10 other IDSM-s in seperate chassis, which work fine.
