Products (1)

  • Cisco Catalyst 4500 Series Switches

Known Affected Releases

Description (partial) 

Symptom:
On C4k , If the switch receives 0000.0000.0000 traffic then puts the switchport to err-disable.
 However, we have the same port security configuration on other switch models (2900, 6500) which do not put the port in err-disable after receiving the same type of packet with the 0000.0000.0000 source MAC

Conditions:
If the switch receives 0000.0000.0000 traffic then puts the switchport to err-disable.
