Release Information

Description
Dynamic interface configuration of the logical link-layer encapsulation type.
Options
atm-ccc-cell-relay—Use ATM cell-relay encapsulation.
atm-ccc-vc-mux—Use ATM virtual circuit (VC) multiplex encapsulation on circuit cross-connect (CCC) circuits. When you use this encapsulation type, you can configure the ccc family only.
atm-cisco-nlpid—Use Cisco ATM network layer protocol ID (NLPID) encapsulation. When you use this encapsulation type, you can configure the inet family only.
atm-mlppp-llc—For ATM2 IQ interfaces only, use Multilink Point-to-Point Protocol (MLPPP) over AAL5 LLC. For this encapsulation type, your router must be equipped with a link services or voice services PIC. MLPPP over ATM encapsulation is not supported on ATM2 IQ OC48 interfaces.
atm-nlpid—Use ATM NLPID encapsulation. When you use this encapsulation type, you can configure the inet family only.
atm-ppp-llc—For ATM2 IQ interfaces only, use PPP over AAL5 LLC encapsulation.
atm-ppp-vc-mux—For ATM2 IQ interfaces only, use PPP over ATM AAL5 multiplex encapsulation.
atm-snap—Use ATM subnetwork attachment point (SNAP) encapsulation.
atm-tcc-snap—Use ATM SNAP encapsulation on translational cross-connect (TCC) circuits.
atm-tcc-vc-mux—Use ATM VC multiplex encapsulation on TCC circuits. When you use this encapsulation type, you can configure the tcc family only.
atm-vc-mux—Use ATM VC multiplex encapsulation. When you use this encapsulation type, you can configure the inet family only.
ether-over-atm-llc—For interfaces that carry IPv4 traffic, use Ethernet over ATM LLC encapsulation. When you use this encapsulation type, you cannot configure multipoint interfaces.
ether-vpls-over-atm-llc—For ATM2 IQ interfaces only, use the Ethernet virtual private LAN service (VPLS) over ATM LLC encapsulation to bridge Ethernet interfaces and ATM interfaces over a VPLS routing instance (as described in RFC 2684, Multiprotocol Encapsulation over ATM Adaptation Layer 5). Packets from the ATM interfaces are converted to standard ENET2/802.3 encapsulated Ethernet frames with the frame check sequence (FCS) field removed.
ether-vpls-over-fr—For E1, T1, E3, T3, and SONET interfaces only, use the Ethernet virtual private LAN service (VPLS) over Frame Relay encapsulation to support Bridged Ethernet over Frame Relay encapsulated TDM interfaces for VPLS applications, as per Multiprotocol Interconnect over Frame Relay(RFC 2427 [1490]).
ether-vpls-over-ppp—For E1, T1, E3, T3 and SONET interfaces only, use the Ethernet virtual private LAN service (VPLS) over PPP encapsulation to support Bridged Ethernet over PPP encapsulated TDM interfaces for VPLS applications.
ethernet—Use Ethernet II encapsulation (as described in RFC 894, A Standard for the Transmission of IP Datagrams over Ethernet Networks).
ethernet-vpls—Use Ethernet VPLS encapsulation on Ethernet interfaces that have VPLS enabled and that must accept packets carrying standard Tag Protocol ID (TPID) values.
extended-vlan-vpls—Use extended virtual LAN (VLAN) VPLS encapsulation on Ethernet interfaces that have VLAN 802.1Q tagging and VPLS enabled and that must accept packets carrying TPIDs 0x8100, 0x9100, and 0x9901.
 | Note: The built-in Gigabit Ethernet PIC on an M7i router does not support extended VLAN VPLS encapsulation. |
frame-relay-ccc—Use Frame Relay encapsulation on CCC circuits. When you use this encapsulation type, you can configure the ccc family only.
frame-relay-ppp—Use PPP over Frame Relay circuits. When you use this encapsulation type, you can configure the ppp family only. J Series routers do not support frame-relay-ppp encapsulation.
frame-relay-tcc—Use Frame Relay encapsulation on TCC circuits for connecting unlike media. When you use this encapsulation type, you can configure the tcc family only.
frame-relay-ether-type—Use Frame Relay ether type encapsulation for compatibility with Cisco Frame Relay. The physical interface must be configured with flexible-frame-relay encapsulation.
frame-relay-ether-type-tcc—Use Frame Relay ether type TCC for Cisco-compatible Frame Relay on TCC circuits to connect unlike media. The physical interface must be configured with flexible-frame-relay encapsulation.
multilink-frame-relay-end-to-end—Use MLFR FRF.15 encapsulation. This encapsulation is used only on multilink, link services,and voice services interfaces and their constituent T1 or E1 interfaces, and is supported on LSQ and redundant LSQ interfaces.
multilink-ppp—Use MLPPP encapsulation. This encapsulation is used only on multilink, link services, and voice services interfaces and their constituent T1 or E1 interfaces.
ppp-over-ether—For underlying Ethernet interfaces on J Series Services routers, use PPP over Ethernet encapsulation. When you use this encapsulation type, you cannot configure the interface address. Instead, configure the interface address on the PPP interface. You also use PPP over Ethernet encapsulation to configure an underlying Ethernet interface for a dynamic PPPoE logical interface on M120 and M320 Series routers with Intelligent Queuing 2 (IQ2) PICs, and on MX Series routers with MPCs.
ppp-over-ether-over-atm-llc—For underlying ATM interfaces on J Series Services routers only, use PPP over Ethernet over ATM LLC encapsulation. When you use this encapsulation type, you cannot configure the interface address. Instead, configure the interface address on the PPP interface.
vlan-bridge—Use Ethernet VLAN bridge encapsulation on Ethernet interfaces that have IEEE 802.1Q tagging, flexible ethernet services, and bridging enabled, and that must accept packets carrying TPID 0x8100 or a user-defined TPID.
vlan-ccc—Use Ethernet virtual LAN (VLAN) encapsulation on CCC circuits. When you use this encapsulation type, you can configure the ccc family only.
vlan-vci-ccc—Use ATM-to-Ethernet interworking encapsulation on CCC circuits. When you use this encapsulation type, you can configure the ccc family only.
vlan-tcc—Use Ethernet VLAN encapsulation on TCC circuits. When you use this encapsulation type, you can configure the tcc family only.
vlan-vpls—Use Ethernet VLAN encapsulation on VPLS circuits.
