Multiple hosts can be configured to be in passive mode and multiple hosts can be connected and receive remote captures at the same time.

Passive mode (default)-The configured host initiates connection to the switch.

RPCAP supports two setup connection modes based on firewall restrictions. This technique prevents an unauthorized machine in the network from snooping on the control traffic in the network. Remote capture can only be performed to explicitly configured hosts. The control connection is used to remotely control the captures (start or stop the capture, or specify capture filters). RPCAP uses two endpoints, a TCP-based control connection and a TCP or UDP-based data connection based on TCP (default) or UDP.

They communicate with each other using the Remote Capture Protocol (RPCAP). The Ethereal analyzer running on a host is the client end. This daemon is the server end of the remote capture component. See the 'Capturing Frames Locally' section. Additionally, because this tool is accessed from within the Cisco MDS 9000 Family switch, it is protected by the roles-based policy that limits access in each switch. It is a fully functional decoder that is useful for quick debug purposes or for use when the remote capture daemon is not enabled. This component is a command-line driven text-based interface that captures traffic to and from the supervisor module in a Cisco MDS 9000 Family switch.

The Cisco Fabric Analyzer is based on two popular public-domain software applications: You can capture Fibre Channel control traffic from a switch and decode it without having to disrupt any connectivity, and without having to be local to the point of analysis. 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.
