Verifying Configured Fctimer Values; World Wide Names - Cisco Nexus 5000 Series Configuration Manual

World Wide Names

• Do not configure global timer values when distribution is enabled.
The number of pending fctimer configuration operations cannot be more than 15. After 15 operations,
Note
you must commit or abort the pending configurations before performing any more operations.
For additional information, refer to CFS Merge Support in the System Management Configuration Guide for
your device.

Verifying Configured fctimer Values

Use the show fctimer command to display the configured fctimer values. The following example displays
the 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
The following example displays the configured TOV for VSAN 10:
switch# show fctimer vsan 10
vsan no.
-------------------------------------------------
10
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.
Cisco SAN switches support three network address authority (NAA) address formats. (see the following table).
