With Rahul Rammanohar 

Hitesh KumarRahul Rammanohar

Welcome to the Cisco Support Community Ask the Expert conversation. This is an opportunity to learn and ask questions about packet capture capabilities of Cisco routers and switches.

In May 2013, we created a video that included packet capture capabilities across multiple Cisco routers and switches. For each product, we began with a discussion about the theory of the capabilities, followed by an explanation of the commands, and we concluded with a demo on real devices. In this Ask the Expert event, you’re encouraged to ask questions about the packet capture capabilities of these Cisco devices:

•       7600/6500: mini protocol analyzer (MPA), ELAM, and Netdr

•       ASR9k: network processor capture

•       7200/ISRs: embedded packet capture

•       Cisco Nexus 7K, 5K, and 3K: Ethanalyzer

•       Cisco Nexus 7K: ELAM

•       CRS: show captured packets

•       ASR1K: embedded packet capture

hello Hitesh & Rahul,

My ASR1K is running a release prior to 3.7.  How do I capture packets on my router?  Thanks in advance for your help.
