This attribute specifies the type of the LAN ID table entry. LAN ID table
entries may be either static or dynamic. Dynamic entries imply that to
reach the desired LAN source route frames need to be tunneled through
a TB/SRT network, to another bridge unit which is attached to the LAN.
These entries have a peerMACAddress associated with them and may be
removed through the aging mechanism of the LAN ID table. Static
entries on the other hand contain information about LANs that may be
reached directly through bridge ports attached to the bridge. They are
not aged and do not have a peerMACAddress associated with them.
