Packet Capturing

[fb_webuser]

Hi

Its been known that Cisco latest IOS releases support capturing on a router using " ip traffic-export profile <> mode capture|export " command but this method only captures OSI layer 3 information and above. Is there any method of capturing layer 2 information like capturing PPP packets, ISDN Q921 packets ?
