Enabling In-Order Delivery Globally; Enabling In-Order Delivery For A Vsan - Cisco Nexus 5000 Series Configuration Manual

In-Order Delivery
intentional pausing of fabric forwarding to purge the fabric of resident frames that could potentially be
forwarded out-of-order.

Enabling In-Order Delivery Globally

To ensure that the in-order delivery parameters are uniform across all VSANs on the switch, enable in-order
delivery globally.
Only enable in-order delivery globally if this is a requirement across your entire fabric. Otherwise, enable
IOD only for the VSANs that require this feature.
To enable in-order delivery for the switch, perform this task:
SUMMARY STEPS
1. switch# configuration terminal
2. switch(config)# in-order-guarantee
3. switch(config)# no in-order-guarantee
DETAILED STEPS
Command or Action
Step 1 switch# configuration terminal
Step 2 switch(config)# in-order-guarantee
Step 3 switch(config)# no in-order-guarantee

Enabling In-Order Delivery for a VSAN

When you create a VSAN, that VSAN automatically inherits the global in-order guarantee value. You can
override this global value by enabling or disabling in-order guarantee for the new VSAN.
To use the lowest domain switch for the multicast tree computation, perform this task:
SUMMARY STEPS
1. switch# configuration terminal
2. switch(config)# in-order-guarantee vsan vsan-id
3. switch(config)# no in-order-guarantee vsan vsan-id
