I just tested this on denali 16.3.7 3650 same issues lanbase exact same config your using, works fine on ip base denali 16.3.7, say your hitting some license limitation as its not a config issue Of course, the EPC only supports buffer option with possibility to export it. I did the same procedure on an IPBASE switch and it work, besides that I didn't store it in buffer but directly had it copied into flash. Switch# monitor capture mycap buffer circular size 30 Switch# monitor capture mycap match ipv4 any any Switch# monitor capture mycap interface GigabitEthernet1/0/3 both The "show monitor capture mycap" also show 0 packets captured. I can export the file to flash or ftp server and open it in wireshark but it's empty. There are no packets captured in the buffer. I can configure it just fine and the output of "show monitor capture mycap" and / or "show monitor capture mycap parameter" lokks good, just as it should be, but. The configuration of the capture is different than Cisco IOS as it adds more features.ģ) The capture can be perform on physical interfaces, sub-interfaces, and tunnel interfaces.Ĥ) The packet buffer is stored in DRAM and will not persist through reloads.I'm currently having some trouble with EPC running on IOS XE WS-C3650-48PD 16.6.5. 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.

The following example shows how to manage packet data capture: 2) The Embedded Packet Capture feature was introduced in Cisco IOS-XE 3.7 - 15.2(4)S. 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.
#CISCO IOS XE EMBEDDED PACKET CAPTURE OFFLINE#
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.
