Command History
Usage Guidelines The Cisco MDS 9000, 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 within in the fabric.
Use the vsan option to configure different TOV values for VSANs with special types of links like FC or
IP tunnels.
Examples The following examples show how to change the default Fibre Channel timers.
switch# config terminal
switch(config)# fctimer e_d_tov 5000
switch(config)# fctimer r_a_tov 7000
