ESRP Cautions
ExtremeWare XOS 11.0 Concepts Guide 249
ESRP and STP
A switch running ESRP should not simultaneously participate in STP for the same VLAN(s). Other
switches in the VLAN being protected by ESRP may run STP; the switch running ESRP forwards, but
does not filter, STP BPDUs. Therefore, you can combine ESRP and STP on a network and a VLAN, but
you must do so on separate devices. You should be careful to maintain ESRP connectivity between
ESRP master and slave switches when you design a network that uses ESRP and STP.
ESRP Groups and Host Attach
ESRP domains that share ESRP HA ports must be members of different ESRP groups.
