Using the show monitor capture buffer dump command we can view the raw packet capture data, but it isn't in a format that Wireshark understands: Normally you can export the resulting packet capture to an FTP or TFTP server, however if this is blocked by firewalls or you don't have access to a suitable server, this is a workaround. The feature allows for network administrators to capture. Packet capture is reachable via the Device Troubleshooting page Monitor > Network > Device name > Troubleshooting. Detailed instructions here: Embedded Packet Capture for Cisco IOS and IOS-XE Configuration Example The Cisco IOS Embedded Packet Capture (EPC) delivers a powerful troubleshooting and tracing tool. Apply access control lists (ACLs) or class maps to capture points.

You can perform the following actions on the capture: Activate captures at any interface.

You can define packet data captures by providing unique names and parameters. Step 2) The tool decodes the output and presents you with a binary copy of the capture and a basic decoding.Most recent Cisco platforms support the Embedded Packet Capture feature, which allows us to take packet captures directly on a router or switch without having to use SPAN to an attached device. Packet Data Capture Packet data capture is the capture of data packets that are then stored in a buffer. Step 1) The tool guide you to collect the capture It helps walk the administrator through configuring the capture, starting the capture, stopping it, and most importantly extracting the capture off the device solely via the SSH/CLI session. Today a new tool for Cisco Customers has been released. With SolarWinds Network Performance Monitor (NPM), IT teams can use network traffic capture to help improve end-user experience. With the iterative nature of troubleshooting multiple capture are often needed forcing the admin to repeat the multiple operations just to get to the packet capture.

However extracting the packet capture from those devices can be an onerous task requiring installation of software, multiple copy operations before the capture can be opened and analyzed. Luckily there are a couple of platforms (IOS, IOS-XE and ASA) that allow packet captures to be taken on the network devices themselves. Many times a packet capture needs to be performed within the network to diagnose network issues.
