Aris,
This is due to the duplex at this specific port.
The switch derives the link type of a port from the duplex mode.
A full-duplex is considered a point-to-point link,
and a half-duplex is considered a shared link.
Look below what is happening by changing the duplex mode:
Enter configuration commands, one per line. End with CNTL/Z.
Central_4507(config)#int fa4/26
Central_4507(config-if)#duplex full
Central_4507(config-if)#do sh spann int fa4/26
