An Ethernet Flow Point (EFP) is a Metro Ethernet Forum (MEF) term describing abstract router architecture. Here, You have configured VLAN ID 633. The documentation set for this product strives to use bias-free language. After a subinterface is defined, use the encapsulation dot1q command to add outer and inner VLAN ID tags to allow one VLAN to support multiple VLANs. The other end of the link is not even configured as a trunk, yet it shows 802. Negotiation of Trunking: On. When using desirable to set trunks it will negotiate on its own. end DETAILEDSTEPS CommandorAction Purpose EnablesprivilegedEXECmode. 1Q encapsulation with the specified VLAN as the default VLAN.

This mode enables a Layer 2 sub-interface to receive packets with a VLAN tag. ingress enables forwarding of incoming traffic on the destination port and to specify the encapsulation type: dot1q vlan vlan-id— Accepts incoming packets with IEEE 802. 1Q) is the industry standard VLAN Tagging Protocol. 3. 16. what does it mean actually ? configuration as below, example1:-----int fa 2/1 . Hope this helps. 1Q. The same Switchport Trunk Encapsulation dot1q. 1Q encapsulation of traffic on a specified subinterface in a virtual LAN (VLAN), use the encapsulation dot1q command. 0 R1(config-subif) #exit R1(config) #int fastEthernet 0/0. On later switches, you can set to trunk without setting encapsulation because the switch will only support dot1q. Explanation: In router-on-a-stick, the subinterface configuration should match the VLAN number in the encapsulation command, in this case, the command Hi,Do you see "switchport mode trunk" command?If so, what you observe implies that ISL is not supported. You can assign a specific inner VLAN ID to the subinterface; that subinterface is unambiguous. R1(config)# int g0/0. To enable IEEE 802. In this case, VLAN 10 becomes the 4. 1Q encapsulation for the subinterface. 252. 254 255. Enables dot1q trunking encapsulation on the interface. 128 the default gateway should be 10. 1Q) Dot1Q (IEEE 802. 1Q tag. Trunking Cisco. load-interval 30. Didalam header dot1q memuat beberapa informasi seperti priority yang menunjukan nilai prioritas dari frame data tersebut, dan VLAN-ID yang sudah saya jelaskan sebelumnya untuk menunjukan frame data tersebut encapsulation dot1q [vlan-id] 功能：配置以太网子接口vlan号，封装格式为802. All the other VLANs need to be configured on the sub-interfaces of the physical port and it is there that the "encapsulation dot1q " command is required. 1Q and assign VLAN 10 to the subinterface. In you have VLAN1 which is native VLAN, you need to set IP address on main interface. I am trying to configure a 4507 R chassis with Dual SUP but i cannot see teh switchpot mode trunk encapsulation dot1q? The supervisor card isn't the only factor if the commend "switchport encap dot1q" is supported or not. I can't hostname R1 ! interface FastEthernet0/0 no ip address duplex auto speed auto ! interface FastEthernet0/0. If user wants to trunk between a Cisco switch link and a different brand switch link, then have to use 802. switchport trunk encapsulation dot1q. 18 255. X 255. 0. I can only enter allowed, native, or pruning. Cisco Nexus 9000 Series Use the vlan dot1q tag native global configuration command to configure the edge devices so that all packets going out an IEEE 802. Currently, this is always 802. 1Q Hi Rutvij, Hope below helps to understand dot1q and Q-In-Q ,. IEEE 802. 1Q as the trunking protocol and associates VLAN 1 to this subinterface. 1Q (QinQ) port, the encapsulation of the Ethernet flow point (EFP) of the Now will change it to dot1q: SW1(config-if) #switchport trunk encapsulation dot1q . Example 17-2 shows both native VLAN configuration options with a small change to the same configuration in Example 17-1. Administrative Trunking Encapsulation: dot1q. let’s say there are 3 vlans- vlan 1,2,3. ip policy route-map RedOperativaB . 1Q (dot1q). cl/2hvyav0 - This tutorial explains what 802. See the "Configuration Examples for IEEE 802. Verify that the VLAN subinterface is active: encapsulation dot1Q; errdisable detect cause; errdisable recovery cause; errdisable recovery interval; ethernet oam; ethernet oam profile; encapsulation dot1Q. One end of the trunk is configured as an 802. To remove the VLAN ID assignment, use the no form of this command. now my trunk link connecting the switch and the router uses dot1q. For some devices, you may also specify the logical link layer encapsulation type. Syntax. 1Q encapsulation is configurable on Fast Ethernet interfaces. The "switchport mode trunk" command will be sufficient to form a dot1q trunk. duplex (Optional) Enter encapsulation dot1q to specify that the destination interface uses the IEEE 802. 25. 1Q tunneling (aka Q-in-Q) is often used by Metro Ethernet providers as a layer 2 VPN for customers. This tag carries information about the specific VLAN to which the frame and packet Cisco switches have traditionally supported two encapsulation methods for trunk s: ISL and dot1q . See Table 1 for Some switch models require the command "switchport trunk encapsulation dot1q" to be set on a port prior to enabling the port as "switchport mode trunk". 1Q inserts a 4-byte header, also called a tag into the original Ethernet frame (right after Source Address field) instead of encapsulating the Ethernet header. As a CCNA you will be required to understand the operation of both trunk encapsulation protocols and how to configure, verify and troubleshoot trunks links using either ISL or Dot1q. now on the router i configure 2 sub-interfaces- one using dot1q 2 and the other using dot1q 3. encapsulation dot1Q 633 .
