portCfg
2
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 will
not be cleared.
fciptunnel Creates Fibre Channel over IP (FCIP) tunnels. You can configure up to a
maximum of 8 FCIP tunnels per GbE port. This feature requires a Brocade
FCIP license. The syntax for portcfg fciptunnel is as follows:
portcfg fciptunnel [slot/][ge]port options args [optional_args]
The following options and args 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 FCIPtunnel 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 will be 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. time values are 20 to
5,000; default is 100.
-n remote_wwn Specifies the remote-side FC entity WWN.
-q control-dscp Specifies the DSCP (DiffServ Code Point) Marking used for control TCP
connection of the FCIP tunnel. This Operand is Optional. Range is 0 to 63
(inclusive). Default value is 0.
