Display information about VLANs configured on bridged Ethernet interfaces. For interfaces configured to support a VoIP VLAN and a data VLAN, the
8 command displays both tagged and untagged membership for those VLANs.show vlans
Note:
When a series of VLANs is created using the
9 statement, such VLAN names are preceded and followed by a double underscore. For example, a series of VLANs using the VLAN range 1 through 3 and the base VLAN name marketing would be displayed as __marketing_1__, __marketing_2__, and __marketing_3__.show vlans
