FCIP Tunnel modify and delete options NOTE: Using the tunnel Modify option disrupts traffic on the specified FCIP tunnel for a brief period of time. Following is the syntax for the portCfg fcipTunnel command to modify FCIP tunnels (you must specify at least one characteristic to modify): portcfg fciptunnel [slot/][ge]port args [optional_args] modify [] [] [] [] [] [] [] where: -b comm._rate New committed traffic rate in Kb/sec on the existing FCIP tunnel. -c 0|1 Disables (0)/Enables (1) compression on the existing FCIP tunnel. -f 0|1 Enables (1)/Disables (0) fastwrite. -k timeout New keep-alive timeout on the existing FCIP tunnel. A range of valid values is 8 through 7200 sec. If tape pipelining is enabled, the default and minimum value is 80 sec. -m time New minimum retransmit time for the existing FCIP tunnel. A range of valid values is 20 through 5000 ms (milliseconds). -r retransmissions 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 sec). If you change this value, the value specified must be greater than the calculated value. -s 0|1 SACK ON (1)/SACK OFF (0) on the existing FCIP tunnel. -t 0|1 Enables (1)/Disables (0) tape pipelining on the existing tunnel. If tape pipelining is enabled, you must also enable fastwrite. The following example shows two tunnels created on slot 8, port ge0; the first with an uncommitted bandwidth (0): switch:admin06> 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 local IP interface : switch:admin06> portcfg fciptunnel 3/ge0 create 6 10.1.1.44 192.168.131.124 155000 Following is the syntax for the portCfg fcipTunnel command to delete FICP tunnels: portcfg fciptunnel [slot/][ge]port args [optional_args] delete The following example shows two tunnels deleted on slot 8, port ge0: switch:admin06> portcfg fciptunnel 8/ge0 delete 6 switch:admin06> portcfg fciptunnel 8/ge0 delete 7 386 Configuring and monitoring FCIP tunneling
