Note: Enter commands in lowercase only; mixed case is for readability. portCfg 2 Fabric OS Command Reference Manual Publication Number: 53-1000240-01 -key preshared-key Specifies the preshared-key to be used during IKE authentication. Its length can be up to a maximum length is 32 bytes. It must be a double quoted string of alpha-numeric characters. The value of this key must be at least 12 bytes. This argument must be used together with -ike and -ipsec. This argument cannot be used together with -f (fastwrite) or -t (tape pipelining). -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. -r retransmissions Specifies the maximum retransmissions. retransmissions values are 1 to 8; default is 8.If tape pipelining is enabled, default value is calculated based on the mininum retransmit time to ensure that tcp connection does not timeout before the host times out. If the user changes this value, the value specified must be greater than the calculated value. -s Disables selective acknowledgement code (SACK) on the tunnel specified. -t Enable tape pipelining on the tunnel specified (requires fastwrite to be turned on as well). This argument cannot be used together with -ike, -ipsec or -key (IPSec). • Note: Only a single IPSec-enabled tunnel can be configured on a port. No other tunnels (IPSec or otherwise) can be configured on the same port. Jumbo frames will not be supported on secure tunnels. Only a single route is supported on an interface with a secure tunnel. • modify tunnel_id Modifies the properties of the existing FCIP tunnel. This will disrupt the traffic on the FCIP tunnel specified for a brief period of time. However, if the FCIP tunnel has IPSec enabled, it cannot be modified. To change it, you must delete it and recreate it. optional_args for modify include: -b comm_rate Specifies the new desired committed rate for the existing tunnel. -c 0|1 Disable (0) or Enable (1) compression on the existing tunnel. -f 0|1 Disable (0) or Enable (1) fastwrite on the existing tunnel.. -k timeout Specifies the keep alive timeout, in seconds for the existing tunnel. timeout values are 8 to 7,200; default is 10. If tape pipelining is enabled, minimum value is 80. -m time Specifies the minimum retransmit time, in milliseconds for the existing tunnel. time values are 20 to 5,000; default is 100. -r retransmissions 2-437
