It performs a zone check between the source and destination. In addition, two Fibre Channel Extended Link Service (ELS - Dell Brocade 300 | Fabric OS Troubleshooting and Diagnostics Guide v7.1.0 - Page 33

you can optionally specify. When you issue the fcPing --allpaths command without any other options, superping covers all ISLs in the routes between source to destination, as shown in Figure 1.

path record some failures. But the ISL with the actual error, has the maximum percentage of failures, as this ISL when selected in any possible path causes the echo frame to be dropped and accumulates a higher failure percentage.

with trunk ports, only the trunk master index is output to the user i.e. individual coverage statistics of each trunk-member is not available. • All switches must have Fabric OS v6.3.0 or later. • Superping requires that the FC Echo ELS frame is supported by end-devices. • In TI Zones, when failover - Dell Brocade 300 | Fabric OS Troubleshooting and Diagnostics Guide v7.1.0 - Page 37
and recommended action As LSAN zone databases get bigger, it takes more switch resources to process them. Use the enforce tag feature to prevent a backbone switch from accepting unwanted LSAN zone databases into its local database.

as a result they end up timing out. Use the speed tag feature to always present target proxy to the host and import them faster. This helps sensitive hosts to do a quick discovery without timing out or cause an application failure. 22 Fabric OS Troubleshooting and Diagnostics Guide 53-1002751-01 - Dell Brocade 300 | Fabric OS Troubleshooting and Diagnostics Guide v7.1.0 - Page 39
A Gigabit Ethernet switch port configured for an FCIP tunnel is called a VE port (virtual E-port). However, with a VEX_Port at the other end it does not propagate fabric services or routing topology information from one edge fabric to another.

The portLoopbackTest command is - Dell Brocade 300 | Fabric OS Troubleshooting and Diagnostics Guide v7.1.0 - Page 47
when ports on one side of the link are disabled. • The disc_c3 errors are discarded class 3 errors, which means that the switch is holding onto the frame longer than the hold time allows.
