Configuring the MAC port security feature
32
Re-enabling a port
Once a port is permanently shut down, an administrator must re-enable the port by entering the
following command.
BigIron RX(config)# int e 7/11
BigIron RX(config-if-e100-7/11)#enable
Syntax: enable
Port security MAC violation limit
You can specify how many packets the system can receive in a one-second interval from denied
MAC address before the system shuts the port down. To enable this new mode, enter a command
such as the following.
BigIron RX(config)#global-port-securit
y
BigIron RX(config-port-security)#violation restrict 12
Syntax: violation restrict [#-denied-packets processed]
Enter 1 – 64000. There is no default.
NOTE
With the introduction of this command, packets from denied MAC addresses are now processed in
software by the LP. They are no longer programmed in the hardware.
In addition to the new processing of packets from denied MAC addresses, these packets can now
be logged in the Syslog. And to prevent the Syslog from being overwhelmed with messages for
denied packets, you can specify how many messages will be logged per second, based on a
packet’s IP address.
BigIron RX(config)#global-port-securit
y
BigIron RX(config-port-security)#violation restrict 12
BigIron RX(config-port-security)#deny-log-rate
<7>
Syntax: deny-log-rate [
<#-logs>
]
Enter 1 – 10. There is no default.
The logged message contains the packet’s IP address and the MAC address of the denied packet.
For example, the following configuration shows that violation restrict is configured;
interface ethernet 14/1
port security
enable
maximum 5
violation restrict 1000
secure-mac-address 0000.0022.2222 10
secure-mac-address 0000.0022.2223 10
secure-mac-address 0000.0022.2224 10
secure-mac-address 0000.0022.2225 10
secure-mac-address 0000.0022.2226 10
When packet from MAC address 000.0022.2227, an address that is not a secured MAC address,
the following Syslog message is generated.
SYSLOG: Mar 10 17:36:12:<12>3-RW-Core-3, Interface e14/1 shutdn due to high rate
of denied mac 0000.0022.2227, vlan 10
