[c-nsp] "The TCN only has an impact on the aging time"

[Kamlesh Sharma]

 As stated in the sentence
"The TCN only has an impact on the aging time"

When there is a TC-N received by the switch. It will change it's aging time
to 15 sec or max_age + forwarding delay = 35.

My confusion is :
it will change it's aging time for whole mac forwarding table
or

Case 1 - TCN recieved on access port for VLAN 20
age out all mac address learned on that access VLAN 20

Case 2 - TCN received on trunk port for VLAN 2 and VLAN 3

age out for all mac address learned on the trunk for VLAN 2 and VLAN 3

Case 3 - TCN received on trunk port for all allowed VLAN

age out for whole MAC forwarding table.

Thanks
