This read-only SnmpAdminString gives the textual name of the local port a feeder is connected to, matching the ifName of the interface identified by cwtLocalIfIndex, or an empty string if that interface has no textual name. An admin reads this to get a human-readable label for the feeder's local attachment port instead of just a numeric ifIndex. For example, seeing cwtLocalIfName return an empty string tells the admin the underlying interface simply has no configured ifName, not that something is misconfigured.
