Download EPUBSelective VLAN Mapping to VPLS
ExtremeXOS currently supports filtering a set of CVIDs received on a VMAN port by classifying the port as a CEP. Since a VPLS can already be configured to carry VMAN traffic, ExtremeXOS 15.4 release extends support for mapping a CEP to a VPLS.
VMAN is the VLAN stacking feature in EXOS. It has two types of ports: access
and network. The access port can be both aware or unaware of VLAN. The customer edge port is the
VLAN aware port of VMAN. The CEP allows several configurable options:
- An Ethernet port can be associated with multiple VMANs based on the CVIDs.
- Multiple CVIDs on multiple Ethernet ports can be associated with a VMAN.
- A range of CVIDs can be specified instead of individually configured.
- CVID translations and egress filtering.
VMAN with CEP ports can work as a way to achieve some of the requirements. However, you cannot currently assign it to a VPLS.
When implemented, a VMAN with CNP, or CEP, or both can be assigned as a service to a VPLS. This feature does not add any other capability beyond associating a VMAN with CEP port to a VPLS. Existing VMAN features such as CVID translation and egress filtering do not change. The existing VPLS feature to include or exclude SVLAN also does not change.
Supported Platforms
VLAN mapping to VPLS is supported on the following platforms:
- Summit X460-G2 (supported from ExtremeXOS 15.6)
- Summit X670-G2 (supported from ExtremeXOS 15.6)
- Summit X770
Limitations
The Selective VLAN Mapping to VPLS feature has the following
limitations:
- You cannot assign multiple VMANs to a VPLS.
- You cannot use SNMP and XML to assign a VMAN with CEP port to VPLS.
