Cisco Nexus 5000 Series - In-Order Delivery

DETAILED STEPS
PurposeCommand or Action
Enters global configuration mode.configure terminal
Example:
switch# configure terminal
switch(config)#
Step 1
Configures the route for the specified Fibre Channel interface
and domain. In this example, the specified interface is assigned
an FC ID and a domain ID to the next hop switch.
fcroute fcid interface fc slot/port domain domain-id
vsan vsan-id
Example:
switch(config)# fcroute 111211 interface fc 1
2 domain 3
Step 2
Configures the route for the specified SAN port channel
interface and domain. In this example, interface san-port-channel
fcroute fcid interface san-port-channel port domain
domain-id vsan vsan-id
Step 3
1 is assigned an FC ID (0x111211) and a domain ID to the next
hop switch.
Example:
switch(config)# fcroute 0x111211 interface
san-port-channel 1 domain 4 vsan 10
Configures the static route for a specific FC ID and next hop
domain ID and also assigns the cost of the route.
fcroute fcid interface fc slot/port domain domain-id
metric value vsan vsan-id
Step 4
Example:
switch(config)# fcroute 0x111211 interface fc
2 1 domain 4 metric 50 vsan 10
If the remote destination option is not specified, the default is
direct.
Adds a static route to the RIB. If this is an active route and the
Forwarding Information Base (FIB) records are free, it is also
added to the FIB.
fcroute fcid interface fc slot/port domain domain-id
metric value remote vsan vsan-id
Example:
switch(config)# fcroute 0x111211 interface fc
2 1 domain 4 metric 50 remote vsan 10
Step 5
If the cost (metric) of the route is not specified, the default is
10.
Configures the netmask for the specified route in the interface
(or SAN port channel). You can specify one of three routes:
fcroute fcid netmask interface fc slot/port domain
domain-id vsan vsan-id
Step 6
0xff0000 matches only the domain, 0xffff00 matches the domain
and the area and 0xffffff matches the domain, area, and port.
Example:
switch(config)# fcroute 0x111211 netmask
interface fc 2 1 domain 4 vsan 12
In-Order Delivery
In-order delivery (IOD) of data frames guarantees frame delivery to a destination in the same order that they
were sent by the originator.
Some Fibre Channel protocols or applications cannot handle out-of-order frame delivery. In these cases, Cisco
SAN switches preserve frame ordering in the frame flow. The source ID (SID), destination ID (DID), and
optionally, the originator exchange ID (OX ID) identify the flow of the frame.
