Configuring a Fabric Analyzer Chapter 68 Troubleshooting Your Fabric Send documentation comments to [email protected] Sending Captures to Remote IP Addresses Caution You must use the eth2 interface to capture control traffic on a supervisor module. To capture remote traffic, use one of the following options: • The capture interface can be specified in Ethereal as the remote device: rpcap:///eth2 For example: rpcap://cp-16/eth2 rpcap://17.2.1.1/eth2 • The capture interface can be specified either in the capture dialog box or by using the -i option at the command line when invoking Ethereal. ethereal -i rpcap://[:]/ For example: ethereal -i rpcap://172.22.1.1/eth2 or ethereal -i rpcap://customer-switch.customer.com/eth2 Note For example, in a Windows 2000 setup, click Start on your desktop and select Run. In the resulting Run window, type the required command line option in the Open field. Displaying Captured Frames You can selectively view captured frames by using the display filters feature. For example, instead of viewing all the frames from a capture, you may only want to view Exchange Link Protocol (ELP) request frames. This feature only limits the captured view-it does not affect the captured or the saved frames. Procedures to specify, use, and save display filters are already documented in the Ethereal website (http://www.ethereal.com). Some examples of how you can use this feature are as follows: • To view all packets in a specified VSAN, use this expression: mdshdr.vsan == 2 • To view all SW_ILS frames, use this expression: fcswils • To view class F frames, use this expression: mdshdr.sof == SOFf • To view all FSPF frames, use this expression: swils.opcode == HLO || swils.opcode == LSU || swils.opcode == LSA • To view all FLOGI frames, use this expression: fcels.opcode == FLOGI 68-20 Cisco MDS 9000 Family Fabric Manager Configuration Guide OL-8007-10, Cisco MDS SAN-OS Release 3.x
