The member VLAN (Virtual LAN) can belong to only one ESRP (Extreme Standby Router Protocol) domain, and you configure zero or more member VLANs for each ESRP domain.The state of the ESRP device determines whether the member VLAN is in the forwarding or blocking state.
The esrpDomain parameter specifies the name of the ESRP domain, and the vlan_name parameter specifies the name of the member VLAN.
