Where:
slot The number of a slot in a Brocade 48000, a Brocade DCX or DCX-4S
enterprise-class platform that contain an FC4-18i blade. This parameter does
not apply to the stand-alone Brocade 7500 Extension Switch.
ge0|ge1 The Ethernet port used by the tunnel (ge0 or ge1).
tunnel_id The tunnel number (0-7).
remote_ip_addr The IP address for the remote end of the tunnel.
local_ip_addr The IP address for the local end of the tunnel.
comm_rate The committed comm rate for the tunnel.
-c Enables compression on this tunnel.
-s Disables selective acknowledgement code (SACK) on the specified tunnel.
-f Enables FCIP Fastwrite.
-M Enables VC QoS mapping.
-t Enables OSTP on the specified tunnel. If OSTP is enabled, Fastwrite must also
be enabled.
-n remote_wwn The remote-side FC entity WWN.
-k timeout The keep-alive timeout in seconds. The range of valid values is 8 through
7,200 sec and the default is 10. If OSTP is enabled both the default and
minimum values are 80 sec.
-r retransmissions
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 tunnel does not time out before the host times out (about 80
sec). Note that the value specified must be greater than the calculated value.
-m time The minimum retransmit time, in milliseconds. The range of valid values is 20
through 5,000 ms and the default is 100 ms.
-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.
