410 Configuring and monitoring FCIP extension services
2. Issue 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]
where:
slot is the number of a slot in a 4/256 SAN Director or DC Director chassis
that contains an FR4-18i blade. This parameter does not apply to the
stand-alone 400 Multi-protocol Router.
ge0|ge1 is the Ethernet port used by the tunnel (ge0 or Ge1).
tunnel_id is the tunnel number (0 - 7).
modify changes the FCIP tunnel configuration options and parameters.
-b comm_rate is the new committed traffic rate in Kb/sec on the existing FCIP tunnel.
-c 0|1 disables (0) or enables (1) compression on the existing FCIP tunnel.
-s 0|1 disables (0) or enables (1) selective acknowledgement (SACK) on the
existing FCIP tunnel.
-f 0|1 enables (1) or disables (0) 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 is the new keep-alive timeout on the existing FCIP tunnel. A range of
valid values is 8 through 7200 seconds. If tape pipelining is enabled,
the default and minimum value is 80 seconds.
-m time is the new minimum retransmit time for the existing FCIP tunnel. A
range of valid values is 20 through 5000 ms.
-r retransmissions The maximum number of retransmissions on the existing FCIP tunnel. A
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 (about 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 Specifies the PL2_Class_of_Service/Priority, as defined by IEEE 802.1p
for the FCIP control connection. The range is 0-7; the default is 0.
-P data_L2Cos Specifies the PL2_Class_of_Service/Priority, as defined by IEEE 802.1p
for the FCIP data connection. The range is 0-7; the default is 0.
