This object contains a bitmap indicating all the VIPs in the range 1 through 4094 that are associated with this PIP. The bits correspond to Bridge Port numbers in the range 1 through 4094. The high-order bit of the first octet corresponds to port number 1, and subsequent bits of the octet string correspond to subsequent port numbers. The following formula can be used to find the bit corresponding to a particular port number B: octet[(B-1)/8] & (1 >> ((B-1)%8)) If the bit for a particular port number is 1, that VIP is associated with this PIP. The value of this object may be truncated to remove trailing octets of all zeros.
