		Column	Description

		Connected to	If there is a link connecting the port to something
			else, the name of the device/cloud/submap at the
			far end of the link is displayed in this column. If
			the port is not connected, the field is left blank.
		Tagged	This column displays Yes if the port transmits
			packets tagged with the 802.1Q VLAN ID on this

VLAN. The column displays No if the port transmits packets untagged on this VLAN.

Protocol Details button

The Protocol Details button will be grayed for VLANs configured on Layer 2 switches. For VLANs configured on Layer 3 switches, or Layer 3 modules in a chassis, if a VLAN has Layer 3 details configured, this button will be enabled and will launch the VLAN Protocol Details dialog box. If a VLAN has IP interfaces configured, these will be listed in the VLAN Protocol Details dialog box, one row for each IP interface:
