fciptunnel
Fabric OS Command Reference
53-1000599-02
Adds static ARP entry to the ARP table. Specify IP Address and MAC address
for each entry. Use portShow arp with the -lmac option to get the MAC
address.
delete ipaddr
Deletes static ARP entry from the ARP table. Only IP address must be
specified to delete the entry.
flush Flushes the ARP table. Only dynamic entries can be flushed, static entries
cannot be cleared.
Creates Fibre Channel over IP (FCIP) tunnels. You can configure up to a
maximum of eight FCIP tunnels per GbE port. This feature requires an FCIP
license. The syntax for portCfg fciptunnel is as follows:
portcfg fciptunnel [slot/][ge]port options arguments [optional_arguments]
The following options and arguments for are supported with fciptunnel:
create tunnel_id dest_ipaddr src_ipaddr comm_rate
Creates FCIP tunnels, where:
tunnel_id Specifies the FCIP tunnel on the GbE port. Valid values are 0-7.
dest_ipaddr Specifies the IP address for the remote end of theFCIP tunnel. IPv6
addresses are supported on systems running v6.0 or later.
src_ipaddr Specifies the IP address for the local end of the FCIP tunnel. IPv6
addresses are supported on systems running v6.0 or later.
comm_rate Specifies the committed traffic rate on the FCIP tunnel in Kbps. Valid
range is 1, 544 to 1,000,000. Specify "0" for an uncommitted tunnel.
Uncommitted tunnels compete for bandwidth. Changing comm_rate is
potentially disruptive.
Optional arguments for fciptunnel create include:
-c compression Enables compression on the specified tunnel. By default, compression is
off.
-f fastwrite Enables fastwrite on the specified tunnel.
-k timeout Specifies the keep alive timeout, in seconds. Timeout values are 8 to
7,200; default is 10. If tape pipelining is enabled, the minimum
supported value is 80.
-M Turns on default VC QoS mapping in the specified tunnel. Default is off.
There are two ways of prioritizing network traffic over FCIP tunnels:
Differentiated Services (DSCP) and Layer 2 Class of Service (L2CoS). If
the -M option is set, the VC on the FCIP outbound frame is mapped to
both a DSCP and L2CoS value. These default values can be modified on
a per-FCIP tunnel basis with the fciptunnel qosmap option. The -M option
can be turned on or off any time. Qosmap settings are unaffected by the
-M option.
-m time Specifies the minimum retransmit time, in milliseconds. The range is 20
to 5,000; the default is 100.
