are all cisco switches vlan capable?

Almost Cisco switches (both fixed configuration and modular switches) are capable of Vlan configuration. Yes, the standard switches are cheaper. An organization need to deploy a VLAN when they need to manage different work-groups. Routing is needed to provide the communications between two Vlan also.

It allows remote configuration and OS image-management on Cisco switches. In other words, you can deploy equipment on a remote site and configure everything from the HQ — that's called Zero Touch Deployment. ... To check if Smart Install is working you can run the “show vstack config” command on your switch.

Differences: Hardware - The key difference between layer 3 switch vs router lies in the hardware. ... Additionally, designed specifically for use on intranets, a layer 3 switch usually has no WAN ports and features a traditional router usually gets. So layer 3 switch is most used to support routing between VLANs.

VLANs numbered from 1 to 1005 are considered as Standard VLANs and the VLANs range from 1006 to 4094 are considered as Extended VLANs. ... VLAN 1006 to 4094 are extended VLANs which can't be advertised by VTP and the switch must be configured in VTP transparent mode, epically if you using VTP version 1 & 2.

4 Answers. An access port sends and receives untagged frames (i.e. all frames are in the same VLAN), while a trunk port supports tagged frames and thus allows to switch multiple VLANs.

Each VxLAN switch has a VTEP interface. In the Nexus family, this is a virtual interface called an NVE interface. The NVE gets a /32 IP address from a loopback interface, which is advertised into the IGP. The NVE has one or more VNI's bound to it. This is how the VTEP gets access to the LAN segments in the overlay.

Cisco IOS on UNIX (IOU) is another option for running Cisco routers in a virtual environment. It is a fully working version of IOS that runs as a user mode UNIX (Solaris) process. IOU was built as a native Solaris image and runs just like any other program.

The Virtual Switching System (VSS) allows two Cisco Catalyst 6500 or 4500 chassis to bond together so that is seen as a single virtual swich to the rest of the network. ... Configure a virtual switch domain on both switches and configure one switch as “switch 1” and the other one as “switch 2”.

VTP server mode – the default mode for Cisco switches. A switch operating in this mode can create, modify, and delete VLANs. You can also specify other VTP configuration parameters on a VTP server, such as VTP version and VTP pruning, for the entire VTP domain. A VTP server switch will propagate VLAN changes.

Untagged VLANs A switchport may be a 'tagged' or 'untagged' port. ... The switch port is configured with a VLAN ID that it will put into the tag. Most switch ports will use this mode by default, with VLAN ID 1. When a frame leaves an untagged port, the switch strips the VLAN tag from the frame.

Extended VLANs are VLANs within the range of 1006 to 4094. They are mainly used in service provider networks to allow the provisioning of number of customers. ... Extended VLANs are used just like normal VLANs; only different range. Extended VLANs must be configured on Switches that are in VTP Transparent mode only.

By default, all Layer 2 control traffic is associated with VLAN 1. A native VLAN is assigned to an 802.1Q trunk port. Trunk ports are the links between switches that support the transmission of traffic associated with more than one VLAN.

You can also login to the IOS console of your CISCO Switch. Just double click on the Switch in your project window and go to the CLI tab. So that's how you install and use Packet Tracer on Ubuntu 18.04 LTS.

The VXLAN Instance ID (VNID) enables forwarding of the packet through tenant virtual routing and forwarding (VRF) domains within the fabric. ... VXLAN enables ACI to deploy Layer 2 virtual networks at scale across the fabric underlay Layer 3 infrastructure.

To ensure that a VLAN exists between every pair of Trunked switches, an administrator must manually create all the needed VLANs on each of the switches individually. Cisco's VLAN Trunking Protocol (VTP) provides an easier method for maintaining consistent VLAN configuration throughout the switched network.

A network switch is a multiport network bridge that uses MAC addresses to forward data at the data link layer (layer 2) of the OSI model. Some switches can also forward data at the network layer (layer 3) by additionally incorporating routing functionality.

It is possible to mix PVST and MST (RSTP requires MST), but it needs some planning, and it can be fragile, as you have discovered. You would probably be better off using the same STP version across all your switches. You could change the STP on the Cisco switches to match the rest of the switches.
