set maclock firstarrival
D-Series CLI Reference 15-53
Parameters
Defaults
None.
Mode
Switch command, read‐write.
Example
This example shows how to reset the number of allowable static MACs on ge .2.3:
D2(rw)->clear maclock static ge.2.3
set maclock firstarrival
Use this command to restrict MAC locking on a port to a maximum number of end station
addresses first connected to that port.
Syntax
set maclock firstarrival port-string value
Parameters
Defaults
None.
Mode
Switch command, read‐write.
Usage
The maclock first arrival count resets when the link goes down. This feature is beneficial if you
have roaming users—the first arrival count will be reset every time a user moves to another port,
but will still protect against connecting multiple devices on a single port and will protect against
MAC address spoofing.
port‐string Specifies the port on which to reset number of static MAC addresses
allowed. For a detailed description of possible port‐string values, refer to
“
Port String Syntax Used in the CLI ” on page 4‐1.
port‐string Specifies the port on which to limit MAC locking. For a detailed
description of possible port‐string values, refer to “
Port String Syntax Used
in the CLI ” on page 4‐1.
value Specifies the number of first arrival end station MAC addresses to be
allowed connections to the port. Valid values are 0 to 600.
Note: Setting a port’s first arrival limit to 0 does not deny the first MAC address learned on the port
from passing traffic.
