FTRACE concepts
4
Displaying the trace for a tunnel
1. Log on to the switch as admin.
2. Enter the portShow ftrace command.
- For the 7500 and FR4-18i blade, the format is as follows:
portshow ftrace <slot/>geX tunnel_ID stats
- For the 7800 and FX8-24 blade, the format is as follows:
portshow <slot/>vePortNumber stats
Include the slot number for the blades.
The FTRACE structures for a 7800 all come from the same trace pool. If there are multiple
tunnels defined, they will be all traced in the same pool of trace buffers. On the FX8-24,
there are two; a pool for VE_ports 12-21 and a pool for VE_ports 22-31. In Virtual Fabric
configurations, the VE_port used in the portshow ftrace command must exist in the VF
context that is set.
The following is and example of output for a 7800 switch.
switch:admin> portshow ftrace 16 stats
