How do I add a VLAN to a trunk port on a Cisco switch?
To add a VLAN to the trunk, issue the switchport trunk allowed vlan add vlan-list command. This example shows how to remove VLANs 5 through 10 and 12. Add VLAN 7 back and verify the allowed VLANs on the trunk link.
Which is a benefit of VLAN?
VLANs provide a number of advantages, such as ease of administration, confinement of broadcast domains, reduced broadcast traffic, and enforcement of security policies. VLANs provide the following advantages: VLANs enable logical grouping of end-stations that are physically dispersed on a network.
How many VLANs can a switch support?
4096 VLANs
A switch supports a maximum of 4096 VLANs, among which VLANs 0 and 4095 are reserved for system use, and VLAN 1 is the default VLAN. Therefore, you can only create VLANs 2 to 4094. You can repeat the vlan command multiple times.
What kind of VLAN is a catalyst 2960 switch?
A dynamic-access port can belong to one VLAN (VLAN ID 1 to 4094) and is dynamically assigned by a VMPS. The VMPS can be a Catalyst 5000 or Catalyst 6500 series switch, for example, but never a Catalyst 2960 or 2960-S switch. The Catalyst 2960 or 2960-S switch is a VMPS client.
Is the Cisco trunk the same as the VLAN?
The non-Cisco IEEE 802.1Q cloud separating the Cisco switches is treated as a single trunk link between the switches. Make sure the native VLAN for an IEEE 802.1Q trunk is the same on both ends of the trunk link.
What kind of stacking does Cisco 2960-s switch support?
The switch supports homogeneous stacking and mixed stacking. Mixed stacking is supported only with the Catalyst 2960-S switches. A homogenous stack can have up to eight stack members, while a mixed stack can have up to four stack members. All switches in a switch stack must be running the LAN Base image.
Do you need a trunk port for catalyst 2960-s?
If you do not want VTP to globally propagate information, set the VTP mode to transparent. To participate in VTP, there must be at least one trunk port on the switch stack connected to a trunk port of a second switch or switch stack. Stacking is supported only on Catalyst 2960-S switches running the LAN base image.
