484 Configuring and monitoring FCIP extension services
2. Enter the portCfg fcipTunnel command to modify FCIP tunnels. You must specify at least one
characteristic to modify. The command syntax is as follows:
portCfg fciptunnel [slot/]ge[port] modify tunnel_id [-b comm_rate] [-c 0|1] [-s
0|1] [-f 0|1]
[-k timeout] [-m time] [-q control_dscp] [-Q data_dscp] [-p control_L2Cos] [-P
data_L2Cos}
[-r retransmissions] [-t 0|1] [-bstr 0|1 TCP Byte Streaming]
where:
slot The number of the slot in an HP StorageWorks 4/256 SAN Director, an HP StorageWorks DC
SAN Backbone Director or HP StorageWorks DC04 SAN Director Switch enterprise-class
platform that contains an FR4-18i blade. This parameter does not apply to the stand-alone HP
StorageWorks 400 Multi-Protocol Router.
ge0|ge1 The Ethernet port used by the tunnel (ge0 or ge1).
tunnel_id The tunnel number (0 - 7).
modify The modify option changes the FCIP tunnel configuration options and parameters.
-b comm_rate
The new committed traffic rate in Kbps on the existing FCIP tunnel.
-c 0|1 Disables (0) or enables (1) compression on the existing FCIP tunnel.
-s 0|1 Disable (0) or enable (1) selective acknowledgement (SACK) on the existing tunnel.
-f 0|1 Disables (0) or enables (1) FCIP Fastwrite.
-M 0|1 Disables (0) or enables (1) VC QoS mapping.
-t 0|1 Disables (0) or enables (1) Tape Pipelining on the existing tunnel. If Tape Pipelining is enabled,
you must also enable Fastwrite.
-k timeout The keep-alive timeout on the existing FCIP tunnel. The range of valid values is 8 through 7200
seconds. If Tape Pipelining is enabled, the default and minimum value is 80 seconds.
-m time The minimum retransmit time for the existing FCIP tunnel. The range of valid values is 20
through 5000 milliseconds.
-r retransmissions
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 the tunnel does not time out before the
host times out (approximately 80 seconds). If you change this value, the value specified must be
greater than the calculated value.
-q control_dscp
The DSCP marking for the FCIP tunnel’s TCP control connection. The range of valid values is 0
through 63. The default is 0. Before configuring DSCP settings, determine if the IP network you
are using implements PHB, and consult with the network administrator to determine the
appropriate DSCP values.
-Q data_dscp
The DSCP marking for the FCIP tunnel’s TCP data connection. The range of valid values is 0
through 63. The default is 0. Before configuring DSCP settings, determine if the IP network you
are using implements PHB, and consult with the network administrator to determine the
appropriate DSCP values.
-p control_L2Cos
The PL2_Class_of_Service/Priority, as defined by IEEE 802.1p, for the FCIP control connection.
Range is 0-7. Default is 0.
