This object specifies the maximum number of learned and static MAC address entries allowed in the forwarding database for a given VPLS-to-pseudo-wire binding, with 0 meaning no limit is enforced. Admins set this to cap how much forwarding table space a single pseudo wire binding can consume, protecting shared table capacity from being monopolized by one connection. For example, setting vplsPwBindMacAddressLimit to 500 restricts that pseudo wire binding to learning at most 500 MAC addresses before further learning is suppressed.
