I am facing some strange issue with IPS 4270. As soon as I am connecting one interface of IPS into any free port(default configs) on 7609, after some time FWSM stops forwarding traffic for around 5 to 10 minutes. I have never seen this type of problem before. During the problem I have noticed that MSFC forwards traffic properly to other devices but traffic across FWSM halts for some time.
FWSM Code: 4.0(1)
IPS Code: 6.1(2)E3
FWSM COnfigs: Multiple Context configured
IPS Config: Only Interface Pairing configured.
Would appreciate any feedback on this.
