Displays information about one or all VLANs.
| vr-name | Specifies a VR name for which
to display summary information for all VLANs. If no VR name is
specified, the software displays summary information for all VLANs
in the current VR context. Note: User-created
VRs are supported only on the platforms listed for this feature
in the Feature License Requirements document. On switches that do not support
user-created VRs, all VLANs are created in VR-Default and cannot
be moved.
|
| vlan_name | Specifies a VLAN name for which to display detailed VLAN information. |
| vlan_list | Specifies a VLAN list of IDs to display detailed VLAN information. |
| tag | Specifies the 802.1Q tag of a VLAN for which to display detailed VLAN information. |
| detail | Specifies that detailed information should be displayed for all VLANs. |
| ipv4 | Specifies IPv4. |
| ipv6 | Specifies IPv6. |
| ports | Displays VLAN ports information. |
Summary information for all VLANs on the device.
Note
To display IPv6 information, you must issue either the show vlan detail command or show vlan command with the name of the specified VLAN.Unlike many other VLAN-related commands, the keyword vlan is required in all forms of this command except when requesting information for a specific VLAN.
Use the command show vlan to display summary information for all VLANs. It shows various configuration options as a series of flags (see the example below). VLAN names, descriptions, and protocol names may be abbreviated in this display.
Use the command show vlan detail to display detailed information for all VLANs. This displays the same information as for an individual VLAN, but shows every VLAN, one-by-one. After each VLAN display you can elect to continue or quit.
Protocol none indicates that this VLAN was configured with a user-defined protocol that has subsequently been deleted.
Note
The BlackDiamond 8800 series switches, SummitStack, and the Summit family of switches display the Mgmt VLAN in VR-Mgmt.When an IPv6 address is configured for the VLAN, the system may display one of the following two address types in parentheses after the IPv6 address:
You can display additional useful information on VLANs configured with IPv6 addresses by issuing the show ipconfig ipv6 vlan vlan_name command.
When a displayed VLAN is part of a PVLAN, the display includes the PVLAN name and type (which is network, non-isolated subscriber, or isolated subscriber).
When the displayed VLAN is configured for VLAN translation, the display provides translation VLAN information. If the displayed VLAN is a translation VLAN, a list of translation VLAN members appears. If the displayed VLAN is a member VLAN, the display indicates the translation VLAN to which the member VLAN belongs.
Ports that are dynamically added by MVRP are indicated by the symbol "H".
The following is example output of the show vlan command on a switch where PTP and CES are configured (for example, an E4G-200 or E4G-400):
