386 Configuring and monitoring FCIP tunneling
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
< tunnel_num >
[<-b comm._rate >] [<-c 0|1>] [<-f 0|1>] [<-k timeout >] [<-m time >]
[<-r retransmissions >] [<-s 0|1>]
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):
The following example shows an FCIP tunnel created between local IP interface <192.168.131.124>:
Following is the syntax for the
portCfg fcipTunnel
command to delete FICP tunnels:
portcfg fciptunnel [ slot /][ge] port args [ optional_args ] delete < tunnel_num>
The following example shows two tunnels deleted on slot 8, port ge0:
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
switch:admin06> portcfg fciptunnel 3/ge0 create 6 10.1.1.44 192.168.131.124
155000
switch:admin06> portcfg fciptunnel 8/ge0 delete 6
switch:admin06> portcfg fciptunnel 8/ge0 delete 7
