Fibre Channel Time Out Values Chapter 37 Advanced Features and Concepts Send documentation comments to [email protected] Fibre Channel Time Out Values You can modify Fibre Channel protocol related timer values for the switch by configuring the following time out values (TOVs): • Distributed services TOV (D_S_TOV)-The valid range is from 5,000 to 10,000 milliseconds. The default is 5,000 milliseconds. • Error detect TOV (E_D_TOV)-The valid range is from 1,000 to 10,000 milliseconds. The default is 2,000 milliseconds. This value is matched with the other end during port initialization. • Resource allocation TOV (R_A_TOV)-The valid range is from 5,000 to 10,000 milliseconds. The default is 10,000 milliseconds. This value is matched with the other end during port initialization. Note The fabric stability TOV (F_S_TOV) constant cannot be configured. This section includes the following topics: • Timer Configuration Across All VSANs, page 37-2 • Timer Configuration Per-VSAN, page 37-3 • About fctimer Distribution, page 37-4 • Enabling or Disabling fctimer Distribution, page 37-4 • Database Merge Guidelines, page 37-5 Timer Configuration Across All VSANs You can modify Fibre Channel protocol related timer values for the switch. Caution The D_S_TOV, E_D_TOV, and R_A_ TOV values cannot be globally changed unless all VSANs in the switch are suspended. Note If a VSAN is not specified when you change the timer value, the changed value is applied to all VSANs in the switch. To configure timers in Fabric Manager, expand Switches > FC Services and then select Timers & Policies in the Physical Attributes pane. You see the timers for multiple switches in the Information pane. Click the Change Timeouts button to configure the timeout values. You see the dialog box as shown in Figure 37-1. 37-2 Cisco MDS 9000 Family CLI Configuration Guide OL-16184-01, Cisco MDS SAN-OS Release 3.x
