A network engineer showed me the
show vlan output of an HP switch. I know tagged ports are trunk and untagged ports are access in Cisco terms. But can anyone explain the "no untagged port"? How is this used in real environments?
As a configuration command,
no vlan xy untagged n (or just
no untagged n when you're in the
vlan xy context) removes the VLAN
xy as untagged from port
n - so there's no untagged/native VLAN.
In Cisco speak that would be a trunk port without a native VLAN. In contrast to Cisco, on HPE switches you simply assign a VLAN as tagged or untagged to a port (with zero or one untagged VLAN per port). VLAN membership can also be learned dynamically if configured.
