fctimer

To change the default Fibre Channel timers, use the fctimer command. To revert to the default values, use the no form of this 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

d_s_tov milliseconds

Specifies the distributed services timeout value (DS_TOV). The range is from 5000 to 100000 milliseconds.

e_d_tov milliseconds

Specifies the error detect timeout value (ED_TOV). The range is from 1000 to 100000 milliseconds, with a default of 2000.

r_a_tov milliseconds

Specifies the resolution allocation timeout value (RA_TOV). The range is from 5000 to 100000 milliseconds with a default of 10000.

vsan vsan-id

(Optional) Specifies the VSAN ID. The range is from 1 to 4096.


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.

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

This example shows how to change the default Fibre Channel timers:

switch(config)# fctimer e_d_tov 5000 
switch(config)# fctimer r_a_tov 7000
