Managing FCIP tunnels
3
The maximum number of retransmissions on the existing FCIP tunnel. The
range of valid values is 1 through 16. If OSTP 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.
-P data_L2Cos The PL2 Class of Service/Priority, as defined by IEEE 802.1p, for the FCIP
data connection. Range is 0-7. Default is 0.
-bstr 0|1 Enables (1)/Disables (0) TCP Byte Streaming.
The following example shows two FCIP tunnels created on slot 8, port ge0; the first with an
uncommitted bandwidth (0), and the second with a committed bandwidth of 10000
Kbps:
switch:admin> portcfg fciptunnel 8/ge0 create 2 192.168.100.50 192.168.100.40
0
switch:admin06> portcfg fciptunnel 8/ge0 create 3 192.168.100.51
192.168.100.41 10000
The following example shows an FCIP tunnel created between a remote interface 10.1.1.44,
and a local IP interface 192.168.131.124:
switch:admin> portcfg fciptunnel 3/ge0 create 6 10.1.1.44 192.168.131.124
155000
Modifying and deleting QoS Settings
The QosMap option of the portCfg fciptunnel command allows you to modify QoS settings or delete
the QosMap configuration file for a virtual port without bringing the FCIP tunnel down.
NOTE
Modified values are not reset to defaults when the tunnel QoS is disabled and enabled. If you want
to revert to default values, use the -default option.
1. Connect to the switch and log in using an account assigned to the admin role.
2. Enter the portCfg fcipTunnel command to modify QoS settings on a virtual port. You must
specify at least one characteristic to modify. The command syntax is as follows:
