Displaying Configured fctimer Values

Use the show fctimer command to display the configured fctimer values (see Examples
29-14).
Example 29-13 Displays Configured Global TOVs
switch# show fctimer
F_S_TOV
----------------------------------------
5000 ms
The F_S_TOV constant, though not configured, is displayed in the output of the show fctimer command.
Note
Example 29-14 Displays Configured TOVs for a Specified VSAN
switch# show fctimer vsan 10
vsan no.

World Wide Names
The world wide name (WWN) in the switch is equivalent to the Ethernet MAC address. As with the MAC
address, you must uniquely associate the WWN to a single device. The principal switch selection and
the allocation of domain IDs rely on the WWN. The WWN manager, a process-level manager residing
on the switch's supervisor module, assigns WWNs to each switch.
Cisco MDS 9000 Family switches support three network address authority (NAA) address formats (see
