Configuration Guide. Layer 2 Host Interface Port Channels The Fabric Extender supports host interface port channel configurations. You can combine up to 8 interfaces in a standard mode port channel and 16 interfaces when configured with the Link Aggregation Control Protocol (LACP). Note Port channel - Cisco SLM2024T-NA | Software Configuration Guide - Page 15
(DCBX) • Cisco Discovery Protocol (CDP) • Link Aggregation Control Protocol (LACP) Quality of Service The Fabric Extender uses IEEE 802.1p class of service (CoS) values to associate traffic with the appropriate class. Per-port QoS configuration is also supported. Host interfaces support pause frames - Cisco SLM2024T-NA | Software Configuration Guide - Page 16
about SPAN, see the Cisco Nexus 7000 Series NX-OS System Management Configuration Guide.

configured by the administrator. A Fabric Extender must be directly connected to its parent Cisco Nexus Series device via a port channel fabric interface. You configure a chassis ID on a port channel on the switch to identify the Fabric Extender that is discovered through those interfaces.
