### Description

```asn1
swL2IGMPPortMap OBJECT-TYPE
SYNTAX PortList
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"This object indicates which ports belong to the same
multicast group, on a per-VLAN basis. Each multicast group has an
octet string which is indicated by a port map. The most significant
bit represents the lowest numbered port, and the least significant bit
represents the highest numbered port. Thus, each port of the switch is
represented by a single bit within the value of this object. If that bit
has a value of '1' then that port is included in the set of ports; the
port is not included if its bit has a value of '0'(Note that the setting
of the bits corresponding to the port from which a frame is received is
irrelevant). The 4 octets represent one unit port according to its logical
port. If the unit is less than 32 ports, other ports are not affected and
are replaced with zeroes."
