Chapter 45 Configuring Port Security
Port Security Manual Configuration
• If an N port’s nWWN is bound to an F port WWN, then all pWWNs in the N port are implicitly
paired with the F port.
• TE port checking is done on each VSAN in the allowed VSAN list of the VSAN trunk port.
• All port channel xE ports must be configured with the same set of WWNs in the same SAN port
channel.
• E port security is implemented in the port VSAN of the E port. In this case, the sWWN is used to
secure authorization checks.
• Once activated, the configuration database can be modified without any effect on the active
database.
• By saving the running configuration, you save the configuration database and activated entries in the
active database. Learned entries in the active database are not saved.
Adding Authorized Port Pairs
After identifying the WWN pairs that need to be bound, add those pairs to the port security database.
Tip Remote switch binding can be specified at the local switch. To specify the remote interfaces, you can
use either the fWWN or sWWN-interface combination.
To add authorized port pairs for port security, perform this task:
This example enters the port security database mode for VSAN 2:
switch(config)# port-security database vsan 2
This example configures the specified sWWN to only log in through SAN port channel 5:
switch(config-port-security)# swwn 20:01:33:11:00:2a:4a:66 interface san-port-channel 5
This example configures the specified pWWN to log in through the specified interface in the specified
switch:
switch(config-port-security)# pwwn 20:11:33:11:00:2a:4a:66 swwn 20:00:00:0c:85:90:3e:80
interface fc 3/2
This example configures any WWN to log in through the specified interface in any switch:
Command Purpose
Step 1
switch# configuration terminal
switch(config)#
Enters configuration mode.
Step 2
switch(config)# port-security database vsan
vsan-id
switch(config-port-security)#
Enters the port security database mode for
the specified VSAN.
switch(config)# no port-security database vsan
vsan-id
switch(config)#
Deletes the port security configuration
database from the specified VSAN.
Step 3
switch(config-port-security)# swwn swwn-id
interface san-port-channel 5
Configures the specified sWWN to only
log in through SAN port channel 5.
Step 4
switch(config-port-security)# any-wwn interface fc
slot/port - fc slot/port
Configures any WWN to log in through
the specified interfaces.
