mac address of router or switch

I am tracing a mac flap issue that maxed out the cpu on one of our switches and one of the macs that was flapping was 0026.0bxx.xxxx?

Is this the mac for the entire layer 3 switch? When I "show ip arp 10.10.10.10" and 10.10.10.10 is the management ip for the router I also get 0026.0bxx.xxxx. but the output below shows that mac in all vlans not just the management vlan 777?

What does * primary entry and ports Router mean?

#sh mac-address-table address 0026.0bxx.xxxx
Legend: * - primary entry
        age - seconds since last seen
        n/a - not available

  vlan   mac address     type    learn     age              ports

What model Cisco router are you using?  What, if any modules do you have installed?
How are your switches configured physically?  Are you using STP, trunking or other multi-port channeling?

The device causing problems was previously removed there is not a flapping issue at this time.

I am just curious about the mac address and the output shown. I am assuming it is normal but I would like to confirm that.
