Switch Interoperability
Changes if Interoperability Is Enabled
Some vendors cannot use the full range of 239
domains within a fabric.
Domain IDs are restricted to the range 97 to 127, to
accommodate McData's nominal restriction to this
same range. Domain IDs can either be static or
preferred, which operate as follows:
• Static: Cisco switches accept only one domain
ID; if a switch does not get that domain ID it
isolates itself from the fabric.
• Preferred: If the switch does not get its
requested domain ID, it accepts any assigned
domain ID.
All Fibre Channel timers must be the same on all
switches as these values are exchanged by E ports
when establishing an ISL. The timers are F_S_TOV,
D_S_TOV, E_D_TOV, and R_A_TOV.
Verify that the Fabric Stability Time Out Value timers
match exactly.
Verify that the Distributed Services Time Out Value
timers match exactly.
Verify that the Error Detect Time Out Value timers
match exactly.
Verify that the Resource Allocation Time Out Value
timers match exactly.
Trunking is not supported between two different
vendor's switches. This feature may be disabled per
port or per switch.
The default zone operation of permit (all nodes can
see all other nodes) or deny (all nodes are isolated
when not explicitly placed in a zone) may change.
