how to confirm which capabilities have been negotiated

Hello, Do we have an appropriate command to show which BGP capabilities have been negotiated on bird after a peer has been established? Of course, I known I can recognize when I look into packets captured, or confirm it on the neighbor router by using "show ip bgp neighbor x.x.x.x" command (in the case of CiscoIOS). it wouldn't be smart.
