DHCHAP
Table 1-1 identifies switch-to-switch authentication between two Cisco switches in various modes.
Configuring the DHCHAP Mode
To configure the DHCHAP mode for a particular interface, perform this task:

Command Purpose
Step 1
switch# configuration terminal
Enters configuration mode.
Step 2
switch(config)# interface fc
slot/port - slot/port
switch(config-if)#
Selects a range of interfaces and enters the interface
configuration mode.
Step 3
switch(config-if)# fcsp on
Sets the DHCHAP mode for the selected interfaces to be in the
on state.
switch(config-if)# no fcsp on
Reverts to the factory default of auto-passive for these three
interfaces.
Step 4
switch(config-if)# fcsp
auto-active 0
Changes the DHCHAP authentication mode for the selected
interfaces to auto-active. Zero (0) indicates that the port does
not perform reauthentication.
Note The reauthorization interval configuration is the same
as the default behavior.
switch(config-if)# fcsp
auto-active timeout-period
Changes the DHCHAP authentication mode to auto-active for
the selected interfaces. The timeout period value (in minutes)
sets how often reauthentication occurs after the initial
authentication.
switch(config-if)# fcsp
auto-active
Changes the DHCHAP authentication mode to auto-active for
the selected interfaces. Reauthentication is disabled (default).
Note The reauthorization interval configuration is the same
as setting it to zero (0).
