Configuring Fibre Channel Routes

To configure a Fibre Channel route, perform this task:
Command
Step 1
switch# configuration terminal
Step 2
switch(config)# fcroute fcid interface
fc slot/port domain domain-id vsan
vsan-id
switch(config)# fcroute fcid interface
san-port-channel port domain domain-id
vsan vsan-id
switch(config)# fcroute fcid interface
fc slot/port domain domain-id metric
value vsan vsan-id
switch(config)# fcroute fcid interface
fc slot/port domain domain-id metric
value remote vsan vsan-id
Step 3
switch(config)# fcroute fcid netmask
interface fc slot/port domain domain-id
vsan vsan-id

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,
switches in the Cisco Nexus 5000 Series 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.
On a switch with IOD enabled, all frames received by a specific ingress port and destined to a certain
egress port are always delivered in the same order in which they were received.
Use IOD only if your environment cannot support out-of-order frame delivery.
Tip If you enable the in-order delivery feature, the graceful shutdown feature is not implemented.

Purpose
Enters configuration mode.
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.
Configures the route for the specified SAN port
channel interface and domain. In this example,
interface san-port-channel 1 is assigned an FC ID
(0x111211) and a domain ID to the next hop switch.
Configures the static route for a specific FC ID and
next hop domain ID and also assigns the cost of the
route.
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
1
and the FIB records are free, it is also added to the
FIB.
If the cost (metric) of the route is not specified, the
default is 10.
Configures the netmask for the specified route the in
interface (or SAN port channel). You can specify one
of three routes: 0xff0000 matches only the domain,
0xffff00 matches the domain and the area, 0xffffff
matches the domain, area, and port.
