Managing FCIP tunnels Managing FCIP tunnels 3 CAUTION Using the modify option disrupts traffic on the specified FCIP tunnel for a brief period of time. NOTE IPsec-enabled tunnels cannot be modified, they can only be deleted and then recreated with new options. This is because IPsec key negotiation uses many of the parameter values during secure tunnel initialization. 1. Connect to the switch and log in using an account assigned to the admin role. 2. Enter the portCfg fcipTunnel command to modify FCIP tunnels. You must specify at least one characteristic to modify. The command syntax is as follows: portCfg fciptunnel [slot/]ge[port] modify tunnel_id [-b comm_rate] [-c 0|1] [-s 0|1] [-f 0|1] [-k timeout] [-m time] [-q control_dscp] [-Q data_dscp] [-p control_L2Cos] [-P data_L2Cos} [-r retransmissions] [-t 0|1] [-bstr 0|1 TCP Byte Streaming] where: slot The number of the slot in a Brocade 48000, a Brocade DCX or DCX-4S enterprise-class platform that contains an FC4-18i blade.

If OSTP is enabled, you must also enable Fastwrite. -k timeout The keep-alive timeout on the existing FCIP tunnel. The range of valid values is 8 through 7200 seconds. If OSTP is enabled, the default and minimum value is 80 seconds. -m time The minimum retransmit time for the existing FCIP tunnel.

Managing FCIP tunnels
CAUTION
Using the modify option disrupts traffic on the specified FCIP tunnel for a brief period of time.
NOTE
IPsec-enabled tunnels cannot be modified, they can only be deleted and then recreated with new
options. This is because IPsec key negotiation uses many of the parameter values during secure
tunnel initialization.
1.
Connect to the switch and log in using an account assigned to the admin role.
2.
Enter the
portCfg fcipTunnel
command to modify FCIP tunnels. You must specify at least one
characteristic to modify. The command syntax is as follows:

where:
slot
The number of the slot in a Brocade 48000, a Brocade DCX or DCX-4S
enterprise-class platform that contains 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).
modify
The modify option changes the FCIP tunnel configuration options and
parameters.
-b
comm_rate
The new committed traffic rate in Kbps on the existing FCIP tunnel.
-c
0|1
Disables (0) or enables (1) compression on the existing FCIP tunnel.
-s
0|1
Disable (0) or enable (1) selective acknowledgement (SACK) on the existing
tunnel.
-f
0|1
Disables (0) or enables (1) FCIP Fastwrite.
-M
0|1
Disables (0) or enables (1) VC QoS mapping.
-t
0|1
Disables (0) or enables (1) OSTP on the existing tunnel. If OSTP is enabled,
you must also enable Fastwrite.
-k
timeout
The keep-alive timeout on the existing FCIP tunnel. The range of valid values
is 8 through 7200 seconds. If OSTP is enabled, the default and minimum
value is 80 seconds.
-m
time
The minimum retransmit time for the existing FCIP tunnel. The range of valid
values is 20 through 5000 milliseconds.
