configure vman add ports

configure vman vman_name add ports [port_list | all] {tagged | untagged {port-cvid port_cvid} | cep [ cvid cvid_first { - cvid_last } { translate cvid_first_xlate { - cvid_last_xlate } } | port-cvid port_cvid ]

Description

Adds one or more ports to a VMAN.

Syntax Description

vman-name Specifies the name of the VMAN to configure.
vman_id Specifies the ID of the VMAN to configure
all Specifies all switch ports.
port_list Specifies a list of ports.
untagged Configures the specified ports as Customer Network Ports (CNPs).
tagged Configures the specified ports as Provider Network Ports (PNPs), which are also called VMAN network ports.
port-cvid Port's customer VLAN (Virtual LAN) ID used for untagged packets.
port_cvid Customer VLAN ID assigned to untagged packets from 1.

Default

If you do not specify a parameter, the default value is untagged, which creates a CNP.

Usage Guidelines

This command adds ports as either CNPs or PNPs. To add a port to a VMAN as a CEP, use the following command:

configure vman add ports cep

The VMAN must already exist before you can add (or delete) ports. VMAN ports can belong to load-sharing groups.

When a port is configured serve as a CNP for one VMAN and A PNP for another VMAN, it inspects the VMAN ethertype in received packets. Packets with a matching ethertype are treated as tagged and switched across the associated PNP VMAN. Packets with a non-matching ethertype are treated as untagged and forwarded into the associated CNP VMAN.

When a port is configured only as a CNP (an untagged VMAN member), whether the VMAN ethertype is 0x8100 or otherwise, all received packets ingress the associated VMAN regardless of the packet's tagging.

Note

Note

If you use the same name across categories (for example, STPD (Spanning Tree Domain) and EAPS (Extreme Automatic Protection Switching) names), we recommend that you specify the identifying keyword as well as the actual name. If you do not use the keyword, the system may return an error message.

The following guidelines apply to all platforms:

  • You must enable or disable jumbo frames before configuring VMANs. You can enable or disable jumbo frames on individual ports or on the entire switch. See “Configuring Ports on a Switch” in the ExtremeXOS 22.2 User Guide for more information on configuring jumbo frames.
  • Each port can serve in only one VMAN role per VMAN. When multiple roles are configured on a port, each role must be configured for a different VMAN.
  • Multiple VMAN roles can be combined on one port with certain VLAN types as shown in the following table.

Note

Note

If you already configured VLANs and VMANs on the same switch using ExtremeXOS 11.4, you cannot change the VMAN ethertype from 0X8100 without first removing either the VLAN or VMAN configuration.

Example

The following example assigns ports 1:1, 1:2, 1:3, and 1:6 to a VMAN named accounting: 

configure vman accounting add ports 1:1, 1:2, 1:3, 1:6 tag 100

History

This command was first available in ExtremeXOS 11.0.

The cvid keyword was added in ExtremeXOS 15.3.2.

The vman_id variable was added in ExtremeXOS 16.1.

The cvid keyword was removed in ExtremeXOS 21.1.

Platform Availability

This command is available on the Summit X450-G2, X460-G2, X670-G2, X770, and ExtremeSwitching X440-G2, X620, X690, X870 series switches.

1 Subsets of this group are also supported. That is, any two of these items are supported.
2 When a CNP is combined with a CEP or tagged VLAN, any CVIDs not explicitly configured for a CEP or tagged VLAN are associated with the CNP.
3 A PNP (tagged VMAN) and a CNP (untagged VMAN) or CEP cannot be combined on a port for which the selected VMAN ethertype is 0x8100.
4 If the secondary VMAN ethertype is selected for the port, it must be set to 0x8100.
