Chapter 43 Advanced Fibre Channel Features and Concepts World Wide Names Send feedback to [email protected] 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 Note The F_S_TOV constant, though not configured, is displayed in the output of the show fctimer command. 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 10 5000 ms 5000 ms 3000 ms 10000 ms 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 Nexus 5000 Series switches support three network address authority (NAA) address formats (see Table 43-1). Table 43-1 Standardized NAA WWN Formats NAA Address IEEE 48-bit address IEEE extended IEEE registered NAA Type Type 1 = 0001b Type 2 = 0010b Type 5 = 0101b WWN Format 000 0000 0000b Locally assigned IEEE company ID: 24 bits 48-bit MAC address 48-bit MAC address VSID: 36 bits Caution Changes to the world-wide names should be made by an administrator or individual who is completely familiar with switch operations.
