+            standard defined by the IETF that allows IoT Device makers to advertise device specifications, including the intended
+            communication patterns for their device when it connects to the network. The network can then use this intent to author
+            a context-specific access policy, so the device functions only within those parameters. Takes an URL of length up to 255
+            characters. A superficial verification that the string is a valid URL
+            will be performed. See
+            <ulink url="https://tools.ietf.org/html/rfc8520">RFC 8520</ulink> for details. The MUD URL received
+            from the LLDP packets will be saved at the state files and can be read via
