Module: GBNDeviceOEM-MIB
OID (symbolic): GBNDeviceOEM-MIB::oemArchIfaceL2Tunneling
OID (numeric): 1.3.6.1.4.1.13464.1.2.2.3.1.1.1.17
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: When l2 entities (such as STP bridges) conneted across a VPN network, l2 PDUs need delivering through VPN without being processed.To achieve this, users need enbling l2- tunneling on VPN's edge ports, i.e. ports connected to customer bridges. One 32bits width integer variable is used for each port to represent what kind of PDUs need tunneling when coming in this ports.Notes, only the six least-significant bits are used here ,each bit corresponds to one protocol, following is the detail: bit0 <----> CDP bit1 <----> LACP bit2 <----> PAGP bit3 <----> STP bit4 <----> UDLD bit5 <----> VTP bit6-bit31 <--> reserved. when set one, corresponding PDU tunneling is asserted, deasserted otherwise.
What is oemArchIfaceL2Tunneling?
This read-write integer uses its low six bits as a bitmask to select which Layer 2 protocol PDUs (CDP, LACP, PAGP, STP, UDLD, VTP) are tunneled transparently through this port when it connects to a customer bridge across a VPN, so those control PDUs pass through unmodified rather than being processed locally. Admins enable specific bits on VPN edge ports to let customer L2 control-plane traffic pass end-to-end without the provider's switch intercepting it. For example, setting bit3 (value 8) would tunnel customer STP BPDUs through this port so the customer's own spanning tree operates correctly across the VPN.
