Chapter 43 Advanced Fibre Channel Features and Concepts
Switch Interoperability
Note The Cisco Nexus 5000 Series, 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. The
RA_TOV default is 10 seconds, and the ED_TOV default is 2 seconds. Per the FC-SW2 standard,
these values must be the same on each switch within the fabric.
switch(config)# fctimer e_d_tov ?
<1000-100000> E_D_TOV in milliseconds(1000-100000)
switch(config)# fctimer r_a_tov ?
<5000-100000> R_A_TOV in milliseconds(5000-100000)
Step 4 When making changes to the domain, you may or may not need to restart the domain manager function
for the altered VSAN.
• Force a fabric reconfiguration with the disruptive option.
switch(config)# fcdomain restart disruptive vsan 1
or
• Do not force a fabric reconfiguration.
switch(config# fcdomain restart vsan 1
Verifying Interoperating Status
This section highlights the commands used to verify if the fabric is up and running in interoperability
mode.
To verify the resulting status of entering the interoperability command in any switch in the Cisco Nexus
5000 Series, perform this task:
Step 1 Verify the software version.
