Monitor capture PCAP match ipv4 protocol tcp any anyġ) These feature requires Cisco IOS Release 12.4(20)T or later.Ģ) The Embedded Packet Capture feature was introduced in Cisco IOS-XE 3.7 - 15.2(4)S. Monitor capture PCAP interface GigabitEthernet0/3/0 both The following example shows how to manage packet data capture: The below output shows packet capture file sent on TFTP server is analyze using Wireshark. The below images show packet is getting transfer to TFTP server. R1#monitor capture buffer PACKET_CAP export t So first we will export captured packet to TFTP server and then analyze using wireshark as shown below:
In our example TFTP server is connected to R1’s Fa1/1 interface. It’s better to export capture to TFTP or FTP server and check with the help of packet analyzer like Wireshark. !.+M+M+M+M+MĦ6366B60: ABCDABCD ABCDABCD ABCDABCD ABCDABCD +M+M+M+M+M+M+M+MĦ6366B70: ABCDABCD ABCDABCD ABCDABCD ABCDABCD +M+M+M+M+M+M+M+MĦ6366B80: ABCDABCD ABCDABCD ABCDABCD ABCDABCD +M+M+M+M+M+M+M+MĢ0:50:53.783 UTC : IPv4 LES CEF : Fa1/0 NoneĢ0:50:53.855 UTC : IPv4 CEF Turbo : Fa1/0 Noneĥ) Logs are seen in about output is in hexadecimal and difficult to understand. There are various options that can be selected when the buffer is defined. Step1: Define a 'capture buffer' with the specified name and parameters, which are a temporary buffer that captured packets, are stored within. In the following topology we are capturing packets on R1 from and to host 192.168.1.1 and 10.1.1.1.Also we will send capture packet to TFTP server to analyze. This feature also facilitates application analysis and security.
This feature facilitates troubleshooting by gathering information about the packet format.
EPC simplifies network operations by allowing devices to become active participants in the management and operation of the network. Embedded Packet Capture (EPC) is a packet capture facility that allows network administrators to capture packets flowing to, through, and from the device and to analyze them locally or save and export them for offline analysis by using a tool such as Wireshark.
