If we want to configure only the VLANs that pass through the trunk, we will have to select “Hybrid VLAN mode” and add them manually.Īs you have seen, configuring a trunk link is quite simple, although we must follow a series of recommendations when doing it, and pay close attention to the ports where we are configuring it.
Here we can put it in “Link” VLAN mode, check the incoming frames if we want them to be always tagged, not tagged or both, and we can even define a native VLAN. The D-Link DXS-1210-10TS switch allows us greater configurability, in this case, we can configure it in “L2 Features / VLAN Interface”. In this way, we will be passing a trunk of VLANs. in this case, if we want ports 1, 2, 3, 4, 9 and 10 to be in trunk, it is enough to select them all in «tagged» mode. In a D-Link DGS-1210-10MP switch, we can go directly to the VLAN / 802.1Q VLAN menu, and choose that the ports are untagged, tagged or not member. D-Link allows us to configure trunk links directly from a very intuitive graphical user interface, below, you can see how easy it is to configure a trunk link on a switch from this manufacturer. Not everything is going to be Cisco in the world of networks, D-Link is one of the best manufacturers and has the most manageable switches in their portfolio. Configuring a trunk link on D-Link switches That is, according to the example shown from the computer with IP 192.168.10.1 you must ping the computer with IP 192.168.10.2. PRP and HSR are both described in the IEC 62439 3 standard. High availability seamless redundancy (HSR) is a further development of the PRP approach, although HSR functions primarily as a protocol for creating media redundancy while PRP, as described in the previous section, creates network redundancy. Why are we going to pass a VLAN if we are not really going to use it on the other switch? In these cases, we could use the following command: “switchport trunk allowed vlan 10” to allow this VLAN only, since it is much more elegant than not passing all VLANs.įinally, we only have to assign the IP addresses to each computer and you only need to ping to verify that both computers can communicate correctly. HSR High Availability Seamless Redundancy. SW2(config-if)#switchport trunk encapsulation dot1qĪnother very important aspect is that the “switchport mode trunk” command allows you to trunk each and every one of the VLANs, but all switches allow adding or removing the VLAN IDs of this trunk link. SW1(config-if)#switchport mode trunk SW2(config)#interface fa0/24 So, the commands to establish the trunks will be the following: SW1(config-if)#switchport trunk encapsulation dot1q Consequently, we must correct it with the following command: This message tells us that the trunk encapsulation of the interface is not established with the IEEE 802.1Q standard that we mentioned above. It depends on the brand and model you use, whether or not that message will appear.
