Service categories

EPL service

Supports PORT-based transparent transmission.

EVPL service

 * Supports PORT-shared EVPL services.
* Supports VCTRUNK-shared EVPL services.* The services are isolated by VLAN tags.
* The services are isolated by QinQ tags.

EPLAN service

  * Supports the blacklist that can contain 512 records and also the static MAC address table that can contain 512 records. The
blacklist function supports verification of destination MAC addresses only.
* Supports the self-learning of the source MAC address.The capacity of the MAC address table is 16K.The aging time of the MAC
address can be set and queried.
* Supports the configuration of static MAC routes.
* Supports the query of dynamic MAC addresses.
* Supports a maximum of 16 VBs.The maximum number of logical ports for each VB is 68.
* Supports the EPLAN services that are based on the IEEE 802.1d MAC bridge.

EVPLAN service

 * Supports data isolation based on VB+VLAN.
* Supports the setting of a maximum of 4095 VLAN filtering tables.
* Supports the EVPLAN services that are based on the IEEE 802.1q virtual bridge and IEEE 802.1ad provider bridge.
