What is sticky learning Cisco?

What is sticky learning Cisco?

When you enable sticky learning on an interface by using the switchport port-security mac-address sticky interface configuration command, the interface converts all the dynamic secure MAC addresses, including those that were dynamically learned before sticky learning was enabled, to sticky secure MAC addresses and adds …

What is the difference between static dynamic and sticky port-security?

Static secure MAC addresses – configured manually with switchport port-security mac-address mac-address. Sticky secure MAC addresses – like Dynamic secure MAC addresses, MACs are learned dynamically but are saved in the running configuration.

What is sticky in port-security?

Sticky – This is not a violation mode. By using the sticky command, the user provides static Mac address security without typing the absolute Mac address. For example, if user provides maximum limit of 2 then the first 2 Mac addresses learned on that port will be placed in the running configuration.

How do I create a sticky mac-address Cisco?

To enable sticky learning, enter the switchport port-security mac-address sticky command. When you enter this command, the interface converts all the dynamic secure MAC addresses, including those that were dynamically learned before sticky learning was enabled, to sticky secure MAC addresses.

What is sticky Mac Cisco?

Sticky MAC is a port security feature that dynamically learns MAC addresses on an interface and retains the MAC information in case the Mobility Access Switch reboots. Allowing the port to continuously learn MAC addresses is a security risk.

What is port violation?

The Cisco port security violation mode is a port security feature that restricts input to an interface when it receives a frame that breaks the port security settings on the said interface.

What are the three types of port security?

On Cisco equipment there are three different main violation types: shutdown, protect, and restrict.

What are the three methods of implementing port security?

switchport port-security violation

• Protect: – This mode will only work with sticky option.
• Restrict: – In restrict mode frames from non-allowed address would be dropped.
• Shutdown: – In this mode switch will generate the violation alert and disable the port.
• Switch(config)# errdisable recovery cause psecure-violation.

How do I configure Dai?

Configuration Steps

1. Enable DHCP Snooping (if required)
2. Enable DAI on the VLAN(s)
3. Configure the DAI interface trust state.
4. Applying ARP ACLs for DAI Filtering.
5. Configure ARP Packet Rate Limiting.
6. Enabling DAI error-disabled recovery.
7. Configure additional validation.
8. Configure DAI Logging.

Where are sticky MAC addresses stored?

address table
Sticky secure MAC addresses—This type of secure MAC address can be manually configured or dynamically learned. These types of addresses are kept in an address table and in the running configuration.

What is Ethernet channel in Cisco?

EtherChannel is a port link aggregation technology or port-channel architecture used primarily on Cisco switches. It allows grouping of several physical Ethernet links to create one logical Ethernet link for the purpose of providing fault-tolerance and high-speed links between switches, routers and servers.
