Storage vendors for example require in these circumstances that a new baseline is created, a certain run-time has been achieved and separate commands are submitted against the suspected switch or switches. Brocade counters are cumulative and keep doing so until a certain counter wraps, a switch reboots or the statistics are manually cleared. If there is no sign of any obvious physical issue there might be link related problems which can identify performance problems and/or protocol related errors. Performance and Intermittent Error Related Issues Only on special occasions you will be asked to enable additional groups if necessary. The output from the “supportshowcfgshow” command shows which subscripts will be enabled. This can be configured with the “supportshowcfgenable ” and “supportshowcfgdisable ”. The amount and type of information displayed in a supportshow output is depending on the type of switch as well as the collection options enabled in the switch configuration. If the problem is multiswitch related (ISL connections, long distance configurations etc.) we need the supportsave from all relevant switches in the fabric. However, a more complex problem that involves Zoning, Performance, Reboots, CP Failovers, Fabric wide problems etc, requires a “SupportSave” type of collection. If the problem is related to basic “port issues”, a “supportshow” is sufficient. There are 2 types of Data Collection associated with Brocade switches, “supportshow” and “supportsave”. Switchstatuspolicyshow – Show config at when errors are flagged Porterrshow – Like mpstat – shows port info Portstatsshow # – Show stats (netstat -s) on a port Misc Showĭiagshow – Show diagnostics – paged outputĮrrdump – Show diagnostics – no paged output Portperfshow – Show interface mode (duplex) Interfaceshow – Like unix ndd Performance
