master VLAN
In
ESRP (Extreme Standby Router Protocol), the master
VLAN (Virtual LAN) is the VLAN on the ESRP
domain that exchanges ESRP-PDUs and data between a pair of ESRP-enabled devices. You must
configure one master VLAN for each ESRP domain, and a master VLAN can belong to only one
ESRP domain.
