Its associated port number to the address table. Provides dynamic addressing by learning the source address of packets it receives on each port and adding the address and

With multiple MAC addresses supported on all ports, you can connect any port on the device to other network devices. The following table shows the default settings for the MAC address table. If these addresses are saved in the configuration file, when the switch restarts, the interfaceĭoes not need to dynamically reconfigure them. Sticky secure MAC addresses-These can be dynamically learned or manually configured, stored in the address table, and added

Static secure MAC addresses-These are manually configured by using the switchport port-security mac-address mac-address interface configuration command, stored in the address table, and added to the switch running configuration.ĭynamic secure MAC addresses-These are dynamically configured, stored only in the address table, and removed when the switch The switch supports these types of secure MAC addresses: Also, if a station with a secure MAC address configured or learned on one secure port attempts to access another secure If a port is configured as a secure port and the maximum number of secure MAC addresses is reached, when the MAC address ofĪ station attempting to access the port is different from any of the identified secure MAC addresses, a security violation

If you limit the number of secure MAC addresses to one and assignĪ single secure MAC address, the workstation attached to that port is assured the full bandwidth of the port. Source addresses outside the group of defined addresses. When you assign secure MAC addresses to a secure port, the port does not forward packets with You can use the port security feature to restrict input to an interface by limiting and identifying MAC addresses of the stationsĪllowed to access the port. Port Security is not supported on private VLAN ports. Port Security is not supported on EtherChanel interfaces. This number is the total of available MAC addresses, including those used for other LayerĢ functions and any other secure MAC addresses configured on interfaces. The maximum number of secure MAC addresses that you can configure on a switch is set by the maximum number of available MACĪddresses allowed in the system. If you try to set the maximum value to a number less than the number of secure addresses already configured on an interface,

I'll keep trying stuff on my side, but I'm hoping that the above information will make the solution of this puzzle easier. Thanks.Ģc:54:2d:38:e5:aa Local network I have : All the WAP4410N are connected to either Catalysts 4506 or 2960, VLAN is enabled, Default VLAN ID is not default, VLAN Tag is set to 'Untagged' and VLAN Tag over WDS is set to 'Disabled'.

While not a real issue - I can still make their IP static and be done with it - I want to understand what is happening and why. Sometimes not, with yet another slight variation on the MAC address.

If I reboot them either from the web interface or by doing a 'shut no shut' on the POE link, they sometimes revert to the original MAC address. I noticed this because I assigned static leases to them through our isc-dhcpd, and couldnt connect to them via their supposed IP address. the one printed on the products body) apparently changes for no reason (that I can understand anyway). I'm having a weird issue with a dozen WAP4410N we just bought : The MAC address assigned to them (i.e.
