Syntax Description
Command Modes User EXEC
Privileged EXEC
Command History
Usage Guidelines In the show vlan mtu command output, the MTU_Mismatch column shows whether all the ports in the
VLAN have the same MTU. When yes appears in this column, it means that the VLAN has ports with
different MTUs, and packets that are switched from a port with a larger MTU to a port with a smaller
MTU might be dropped. If the VLAN does not have an SVI, the hyphen (-) symbol appears in the
SVI_MTU column. If the MTU-Mismatch column displays yes, the names of the port with the MinMTU
and the port with the MaxMTU appear.
If you try to associate a private VLAN secondary VLAN with a primary VLAN before you define the
secondary VLAN, the secondary VLAN is not included in the show vlan private-vlan command output.
brief (Optional) Display one line for each VLAN with the VLAN name, status,
and its ports.
dot1q tag native (Optional) Display the IEEE 802.1Q native VLAN tagging status.
id vlan-id (Optional) Display information about a single VLAN identified by VLAN
ID number. For vlan-id, the range is 1 to 4094.
internal usage (Optional) Display a list of VLANs being used internally by the switch.
These VLANs are always from the extended range (VLAN IDs 1006 to
4094), and you cannot create VLANs with these IDS by using the vlan
global configuration command until you remove them from internal use.
mtu (Optional) Display a list of VLANs and the minimum and maximum
transmission unit (MTU) sizes configured on ports in the VLAN.
name vlan-name (Optional) Display information about a single VLAN identified by VLAN
name. The VLAN name is an ASCII string from 1 to 32 characters.
private-vlan (Optional) Display information about configured private VLANs, including
primary and secondary VLAN IDs, type (community, isolated, or primary)
and ports belonging to the private VLAN. This keyword is only supported if
your switch is running the IP services feature set.
type (Optional) Display only private VLAN ID and type.
remote-span (Optional) Display information about Remote SPAN (RSPAN) VLANs.
summary (Optional) Display VLAN summary information.
