Sw Port Security
When you have your outlet ports secured with port-security so that only 2 MAC-Addresses may be visibile on the switchport, otherwise it will shutdown when a third MAC-Addresse is detected.
You will have to set port-security on the switchport by
#conf terminal
#(config) interface fa2/43 <is the linecard and poort>
#(config-if) no switchport port-security mac-address sticky
#(config-if) switchport port-security mac-address sticky
#(config-if) end
# write memory
Always check afterwards how the interface is behaving:
# show interface fa2/43
# show interface
