![]() ![]() The Cisco MDS 9000 Family switches support protocol analysis within a storage network with the Cisco Fabric Analyzer. Also, to snoop traffic, the existing analyzers disrupt the traffic on the link while the analyzer is inserted into the link. They are expensive and support limited frame decoding. Existing Fibre Channel analyzers can capture traffic at wire rate speed. Verifies reachability of the destination switch by checking its end-to-end connectivity.įibre Channel protocol analyzers capture, decode, and analyze frames and ordered sets on a link. To perform a fcping operation, follow these steps:ĥ frames sent, 5 frames received, 0 timeouts You can invoke the fcping feature by providing the FC ID, the destination port WWN, or the device alias information. ![]() The fcping feature verifies reachability of a node by checking its end-to-end connectivity. Invokes fctrace using the device alias of the destination N port. Invokes fctrace using the pWWN of the destination N port.īy default the period to wait before timing out is 5 seconds, The range is from one through 10 seconds. Invokes fctrace for the specified FC ID of the destination N port. If the destination cannot be reached, the path discovery starts, which traces the path up to the point of failure. ![]() Once the frame reaches the edge of the fabric (the F port or FL port connected to the end node with the given port WWN or the FC ID), the frame is looped back (swapping the source ID and the destination ID) to the originator. The frames are routed normally as long as they are forwarded through TE ports. You can invoke fctrace by providing the FC ID, the N port, or the NL port WWN, or the device alias of the destination. Compute inter-switch (hop-to-hop) latency.Trace the route followed by data traffic.This chapter includes the following sections: This chapter describes basic troubleshooting methods used to resolve issues with switches.
