ExtremeXOS provides a configurable per-port “display-string” parameter that is displayed on each of the show port CLI commands, exposed through the SNMP ifAlias element, and accessible through the XML port.xsd API. Previously, the field was limited to 20 characters. This feature provides a new and separate per-port field call “description-string” that allows you to configure strings up to 255 characters.
The first character should by alphanumeric.
This new field is CLI accessible only through the show port info detail command, but you can also access it through the SNMP ifAlias object of IfXTable from IF-MIB (RFC 2233), and through the XML API.
