To change the default Fibre Channel timers, use the fctimer command. To revert to the default values,
use the no form of the command.
fctimer {d_s_tov milliseconds | e_d_tov milliseconds | r_a_tov milliseconds} [vsan vsan-id]
no fctimer {d_s_tov milliseconds | e_d_tov milliseconds | r_a_tov milliseconds} [vsan vsan-id]
Syntax Description
Command Default The Fibre Channel timers have the following default values:
• 30 seconds for DS_TOV.
• 2 seconds for ED_TOV.
• 10 seconds for RA_TOV.
Command Modes Configuration mode
Command History
Usage Guidelines The Cisco, Brocade, and McData FC Error Detect (ED_TOV) and Resource Allocation (RA_TOV)
timers default to the same values. They can be changed if needed. In accordance with the FC-SW2
standard, these values must be the same on each switch in the fabric.
Use the vsan option to configure different TOV values for specific VSANs.
Examples The following example shows how to change the default Fibre Channel timers:
switch(config)# fctimer e_d_tov 5000
switch(config)# fctimer r_a_tov 7000
