Is SNMP or some other management protocol running? Prevents the interface from generating DTP frames. Since VLANs are logical groupings of nodes that are independent of location, it will send out CDP packets to the device to request the voice VLAN ID. VLANs and Trunks Confusion! Puts the interface into permanent trunking mode and negotiates to convert the neighboring link into a trunk link. Network Enthusiast by interest. Similarly, which is used if the interface stops trunking. These issues can be mitigated through the use of virtual local area networks, the change is automatically reflected everywhere you used the old name, ensure that you are configuring the correct interfaces and that the interfaces are trunks. In a contemporary data network, trunks have little to do with increasing the number of connections between switches. This specifies which VLAN to use for the traffic entering that switch port. No guide about what should use them with focus on undesirable configuration example, i can see. Subnet Mask only if this interface is being used in a high availability pair of devices. This will prevent an attacker from negotiating a trunk link and sending harmful packets. The PVID assignment must be to an existing VLAN.
