USE CASE: Match traffic on ingress module, traffic ingressing on a fabric module and traffic ingressing T2 ASIC on egress module Traffic from modules can hit any fabric module Showing only one fabric in above picture to make it simple. There are upto six fabric modules on a 9500 chassis. Solutionįor more infomation about Nexus 9000 Switch Architecture, refer to: Packet tracer uses TCAM entries carved for SPAN. So packet tracer gives you more insight into how traffic is being forwarded within the switch. You can also trace the packet going up to fabric ports and going towards egress module. In those cases, use packet tracer to match the interested traffic. However on Nexus platform, some of the linecards do not have TCAM carved for PACL. PACL (Port Access-list) is used to see if a particular physical interface received our interested traffic. Two Broadcom Trident II ASIC (T2) instances per fabric module. All fabric moduels are active and carry traffic. Background Informationįabric modules interconenct I/O module slots. The counters can be used to corelate drops. N9K-9508#test packet-tracer src_ip dst_ip One of the fabric module->egress module). Packet-tracer commands are EXEC level commands.

Note: Please reach out to TAC if a specific line card/TOR is not listed How to Use Packet Tracer Configuration Only line cards/Fabric Modules or TORs with Broadcom Trident II asics are supported.

Intermittent packet loss : Ping or any other utility can provide a definite symptom of lost packets.

This tool does not display the packet inner details as shown by wireshark.

Applicable for IPv4 flows only (IPv6 and non IP not supported).

The information in this document is based on these software and hardware versions: Prerequisites RequirementsĬisco recommends that you have basic knowledge of these topics:

It also provides a counter to track flow statistics which can be useful for scenerios of intermittent/complete packet loss. This tool will provide confirmation on whether a flow is traversing through the switch. It can be invoked using the command line and can be configured to match IP address and or layer 4 attributes. I'm so very sorry it is very tricky.Packet-tracer is an inbuilt utility on the Nexus 9000 that can be used to trace the path of the packet through the switch. rwxr-xr-x 1 root admin 1739056 May 13 23:55 libcrypto.dylib This command gives read right on these libraries to everyone (the last r in the access rights). > cd /Applications/Cisco Packet Tracer/Cisco Packet Tracer.app/Contents/FrameworksĪfter typing the following command to get read rights.
