cisco router 2651XM running a sip trunk (call manager express)
broadband access through wic1-adsl card
I'm currently monitoring all my adsl traffic by duplicating the adsl traffic stream out of an ethernet switch port. The config I'm using to do this is:
router(config)#ip traffic-export profile adslwatch
router(conf-rite)#int FastEthernet 1/7
router(conf-rite)#mac-address 0090.27FC.756F (mac address of PC)
router(config-if)#ip traffic-export apply adslwatch
I'm watching the data stream (from Fa1/7) using wireshark on a laptop.
problem is that whenever I make a voip phone call on the sip trunk the router crashes and throws up memory conflicts. I think the voice data stream is too 'heavy' for the cisco to duplicate and stream. So my question is:
1) is there a better config to monitor the adsl traffic?
2) is there a way to filter the monitoring so it only shows voice traffic?
Voice traffic is the only thing I'm interested in when monitoring the adsl traffic.
Thanks for any help.
