This read-only counter reports how many of this port's remTable entries were detected because a standard IEEE 802.1AB LLDP message was received from that neighbor. Admins use it to distinguish neighbors discovered via standards-based LLDP from those discovered by other means (Hirschmann-specific messages or FDB learning), which is useful for confirming a mixed-vendor link is exchanging proper LLDP. For example, a nonzero IEEE entry count on a port confirms it is receiving standard LLDP advertisements from at least one connected device.
