Section 4.9.1 says:
o End-station service disable (trunk port) bit. When this bit is set, all native frames received on the port and all native frames that would have been sent on the port are discarded. (See Appendix B.) (Note that, for this document, "native frames" does not include Layer 2 control frames.) By default, ports are not restricted to being trunk ports. If a port with end-station service disabled reports, in a TRILL- Hello frame it sends out that port, which VLANs it provides end- station support for, it reports that there are none. o TRILL traffic disable (access port) bit. If this bit is set, the goal is to avoid sending any TRILL frames, except TRILL-Hello frames, on the port since it is intended only for native end- station traffic. By default, ports are not restricted to being access ports. This bit is reported in TRILL-Hello frames. If RB1 is the DRB and has this bit set in its TRILL-Hello, the DRB still appoints VLAN forwarders. However, usually no pseudonode is reported, and none of the inter-RBridge links associated with that link are reported in LSPs. If the DRB RB1 does not have this bit set, but neighbor RB2 on the link does have the bit set, then RB1 does not appoint RB2 as appointed forwarder for any VLAN, and none of the RBridges (including the pseudonode) report RB2 as a neighbor in LSPs.
It should say:
o End-station service disable (trunk port) bit. When this bit is set, all native frames received on the port and all native frames that would have been sent on the port are discarded.

Notes:
There is a paragraph in the wrong place so that it appears to apply to the wrong bit.
The second paragraph of bullet item 3 in Section 4.9.1 (the second bullet item at the top of page 72) is in the wrong place and appears to apply to the TRILL traffic disable (access port) bit. This text should instead be part of the previous bullet item and, in fact, applies to the end-station service disable (trunk port) bit.
