Active Connections

You can configure the required mode for initiating an TCP connection. By default, active mode is
enabled to actively attempt an IP connection. If you enable the passive mode, the switch does not initiate
a TCP connection and merely waits for the peer to connect to it.
Note Ensure that both ends of the FCIP link are not configured as passive mode. If both ends are configured
as passive, the connection is not initiated.
To enable the passive mode, follow these steps:
Command
Step 1
switch(config-if)# passive-mode
switch(config-if)# no passive-mode
Step 2
switch(config-if)# no shutdown

Number of TCP Connections

You can specify the number of TCP connections from an FCIP link. By default, the switch tries two (2)
TCP connections for each FCIP link. You can configure one or two TCP connections. For example, the
Cisco PA-FC-1G Fibre Channel port adapter, which has only one (1) TCP connection, interoperates with
any switch in the Cisco MDS 9000 Family. One TCP connection is within the specified limit. If the peer
initiates one TCP connection, and your MDS switch is configured for two TCP connections, then the
software handles it gracefully and moves on with just one connection.
To specify the TCP connection attempts, follow these steps:
Command
Step 1
switch(config-if)# tcp-connection 1
switch(config-if)# no tcp-connection 1
Step 2
switch(config-if)# no shutdown

Time Stamp Control

You can instruct the switch to discard packets that are outside the specified time. When enabled, this
feature specifies the time range within which packets can be accepted. If the packet arrived within the
range specified by this option, the packet is accepted. Otherwise, it is dropped.

Disables special frames (default).
Enables the interface.
Purpose
Enables passive mode while attempting a TCP connection.
Reverts to the factory set default of using the active mode
while attempting the TCP connection.
