| 9.2.3 |  | RSPAN interaction with other features |

In addition to SPAN interaction characteristics, RSPAN interacts in the following way with other switch features:

- Spanning-Tree Protocol (STP) – A reflector port does not participate in STP while its RSPAN session is active. STP can be active on trunk ports carrying an RSPAN VLAN.
- VLAN Trunking Protocol (VTP) – VTP can be used to prune an RSPAN VLAN between switches.
- VLAN and trunking – VLAN membership or trunk settings can be modified for reflector ports at any time. However, changes in VLAN membership or trunk settings for a destination or reflector port do not take effect until the RSPAN session is disabled.
- EtherChannel groups – If a physical port belonging to an EtherChannel group is a reflector port and the EtherChannel group is a source, the port is removed from the EtherChannel group and from the list of monitored ports.
