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

◦
The global fctimer values are not distributed.
•
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,
you must commit or abort the pending configurations before performing any more operations.
Note
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 D_S_TOV E_D_TOV R_A_TOV
----------------------------------------
5000 ms 5000 ms 2000 ms 10000 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. F_S_TOV D_S_TOV E_D_TOV R_A_TOV
-------------------------------------------------

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).
