AMX NXA-ENET24 manual Command Function Switchport allowed vlan Syntax, Switchport gvrp

CLI (Command Line Interface)

Configuring VLAN Interfaces (Cont.)

Command	Function
switchport allowed vlan	Syntax:
This command configures VLAN	switchport allowed vlan {add vlan-list [tagged untagged]
groups on the selected interface.	remove vlan-list}
	no switchport allowed vlan
Use the no form to restore the default.
	• add vlan-list - List of VLAN identifiers to add.
	• remove vlan-list - List of VLAN identifiers to remove.
	• vlan-list - Separate nonconsecutive VLAN identifiers with a comma
	and no spaces; use a hyphen to designate a range of IDs. Do not
	enter leading zeros. (Range: 1-4094).
	Default Setting: All ports are assigned to VLAN 1 by default. The
	default frame type is untagged.
	Command Mode: Interface Configuration (Ethernet, Port Channel)
	Command Usage: A port, or a trunk with switchport mode set to
	hybrid, must be assigned to at least one VLAN as untagged.
	If a trunk has switchport mode set to trunk (i.e., 1Q Trunk), then you
	can only assign an interface to VLAN groups as a tagged member.
	Frames are always tagged within the switch. The tagged/untagged
	parameter used when adding a VLAN to an interface tells the switch
	whether to keep or remove the tag from a frame on egress.
	If none of the intermediate network devices nor the host at the other
	end of the connection supports VLANs, the interface should be added
	to these VLANs as an untagged member. Otherwise, it is only neces-
	sary to add at most one VLAN as untagged, and this should corre-
	spond to the native VLAN for the interface.
	If a VLAN on the forbidden list for an interface is manually added to
	that interface, the VLAN is automatically removed from the forbidden
	list for that interface.
	Example: The following example shows how to add VLANs 1, 2, 5
	and 6 to the allowed list as tagged VLANs for port 1:
	Console(config)#interface ethernet 1/1
	Console(config-if)#switchport allowed vlan add 1,2,5,6
	tagged
	Console(config-if)#
switchport gvrp	See page 263.
switchport forbidden vlan	Syntax:
This command configures forbidden	switchport forbidden vlan {add vlan-list remove vlan-
VLANs.	list}
	no switchport forbidden vlan
Use the no form to remove the list of
	• add vlan-list - List of VLAN identifiers to add.
forbidden VLANs.
	• remove vlan-list - List of VLAN identifiers to remove.
	• vlan-list - Separate nonconsecutive VLAN identifiers with a comma
	and no spaces; use a hyphen to designate a range of IDs. Do not
	enter leading zeros. (Range: 1-4094).
	Default Setting: No VLANs are included in the forbidden list.
	Command Mode: Interface Configuration (Ethernet, Port Channel)
	Command Usage: This command prevents a VLAN from being auto-
	matically added to the specified interface via GVRP.
	If a VLAN has been added to the set of allowed VLANs for an inter-
	face, then you cannot add it to the set of forbidden VLANs for that
	same interface.
	Example: The following example shows how to prevent port 1 from
	being added to VLAN 3:
	Console(config)#interface ethernet 1/1
	Console(config-if)#switchport forbidden vlan add 3
	Console(config-if)#
switchport priority default	Sets a port priority for incoming untagged frames
