Hi, Thanks for writing in.

P2p means Point to point link. The switch determines that it is a point to point link if the link is a full duplex link.

Shr means shared. The switch determines that a port is a shared port if the port is a half duplex link.

Edge: A switch determines that a port is an edge port if the port is configured for spanning tree portfast.

Hope that helps.
