Cisco Switch Portfast
Posted on 2011-02-27
Cisco is saying that portfast can be used on the port that s connected to a single host. it also says that portfast will have effect only when it is used in a Non-Trunking port, which means access port.
So why would we worry about the usage of Portfast since it will have effect only on the access port.?
Why it is not enabled by default on access ports.?
why it can be configured on some access ports only, and not on the other access ports?
And if you enable portfast : spanning-tree portfast default.
it will tell you to explicitly disable it on the ports leading to switches,etc....
I thought it previously said , it will have effect only when applied to non-trunkin ports, why should it ask about explicitly disabling it on ports leading to switches?
any expert to clear it up, please.
