Configuring FCIP tunnels
After you have verified licensing and connectivity between source and destination IP interfaces, you can
configure FCIP tunnels. As you plan the tunnel configurations, be aware that uncommitted rate tunnels use
a minimum of 1000 Kb/sec, up to a maximum of available uncommitted bandwidth on the GbE port. The
total bandwidth available on a GbE port is 1 Gbit/sec. You can configure tunnels as bidirectional entities
with different commit rates in both directions.
NOTE: You cannot create FCIP tunnels that connect a 400 MP Router or 4/256 SAN Director
with a B-Series MP Router blade to an MP Router model.
The syntax for configuring FCIP Tunnels is provided in the following sections. For more information about
Fabric OS commands, see the Fabric OS Command Reference Manual .
FCIP Tunnel create option
Following is the syntax for the
portCfg fcipTunnel
command:
portcfg fciptunnel [ slot /][ge] port args [ optional_args ] create
< tunnel_id > < remote_ip_addr > < local_ip_addr > < comm_rate > [< -csf >] [-n
remote_wwn ] [<-k timeout >] [<-r retransmissions >] [<-m time >] [< -t >]
[-ike < ike_number >] [-ipsec < ipsec_number> ] [-key < preshared_key >]
where:
-c
Enables compression on this tunnel.
-s
Disables selective acknowledgement code (SACK) on the specified tunnel.
-f
Enables fastwrite.
-n remote_wwn
Specifies the remote-side FC entity WWN.
-k timeout
Specifies the keep-alive timeout in seconds. The range of valid values is 8 through
7,200 sec and the default is 10. If tape pipelining is enabled both the default and
minimum values are 80 sec.
-r retransmissions
Specifies the maximum number of retransmissions on the existing FCIP tunnel. The
range of valid values is 1 through 16. If tape pipelining is enabled, the number of
retransmissions is calculated based on the minimum retransmit time to ensure that
tunnel does not timeout before the host times out (about 80 sec). Note that the value
specified must be greater than the calculated value.
-m time
Specifies the minimum retransmit time, in milliseconds. The range of valid values is 20
through 5,000 ms and the default is 100 ms.
-t
Enables tape pipelining. If tape pipelining is enabled, fastwrite must also be enabled.
-ike ike_number
Specifies the IKE policy number to be used for this FCIP tunnel.
-ipsec ipsec_number
Specifies the IPSec policy number to be used for this FCIP tunnel.
-key preshared_key
The preshared key to be used during IKE authentication up to a maximum length of
32 bytes. It can be a double quoted string of alphanumeric characters. The range of
valid values is 12 through 32 bytes.
