Likewise, how do I enable sticky port security? To revert to the default settings, use the no form of this command. To add a static secure MAC address on a Layer 2 interface or to enable sticky MAC address learning on an interface, use the switchport port- security mac- address command. Similarly, how do you secure a MAC address? switchport port- security mac- address. 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. Similarly, you may ask, what does Switchport port security MAC address sticky do? To delete all the sticky addresses on an interface or a VLAN, use the no switchport port- security sticky interface interface-id command. I'm coming originally fr.To delete a sticky secure MAC addresses from the address table, use the no switchport port- security sticky mac- address mac_address command.

OK Community, what can you make of this? Dale. And last, is it possible that the MAC that show up in the interface output is just plain wrong? Can't say I've ever seen this so it seems unlikely, but that appears to be what's happening. Is there a CLI command for showing all MACs on a Cisco ASA 5505? I tried 'show mac-address-table', 'show switch mac-address-table' and out of desperation, 'show ?' There doesn't seem to be a command for this most basic bit of information about the hardware.Ĥ. Are there virtual MAC addresses or something, in addition to MACs tied to real ports?ģ. Does it mean there's a a1a1:a1a1:219c in there somewhere also?Ģ. Where did a1a1:a1a1: 219d come from? That address should fall 2 addresses outside the sequential addresses of the 7 ports that I can query. This is curious because by my count, Ethernet0/7, the last interface, should have MAC a1a1:a1a1: 219b, which it does according to a 'show interface Ethernet0/7'.ġ. Weird, I call the ISP, they tell me the MAC they're seeing connected is a1a1:a1a1 : 219d. I register this MAC with the ISP, set the 'outside' interface to DHCP, hook up the modem, but no Internet. Let's pretend the MAC of Ethernet0/0 shows up as a1a1:a1a1: 2195 in the above output. Should be easy to find the MAC of the port connected to the ISP's modem, right?
