how to configure cisco 2960 switch step by step

Published by on November 13, 2020

The native VLAN is VLAN 1 by default. By default, a trunk port sends traffic to and receives traffic from all VLANs. show interfaces interface-id switchport. Configure the VMPS and the client with the same VTP domain name. Verify that the VLANs exist in the database on Switch A. Note The switch must be running the LAN Base image to support remote SPAN. show vlan { name vlan-name | id vlan-id }. VTP version 1 and version 2 support only normal-range VLANs (VLAN IDs 1 to 1005). Each Ethernet VLAN in the VLAN database has a unique, 4-digit ID that can be a number from 1 to 1001. You can configure a trunk on a single Ethernet interface or on an EtherChannel bundle. For example, all the end stations in a particular IP subnet belong to the same VLAN. The “Enabling VTP Pruning” section on page 15-16 describes how to enable VTP pruning. Note With VTP version 3, the VLAN configuration is also saved in the VLAN database. VTP is recommended but not required. November 4, 2019 in Networking, Networked Audio, and Streaming. For explanations about using the add, all, except, and remove keywords, see the command reference for this release. Stack members have a vlan.dat file that is consistent with the stack master. The non-Cisco IEEE 802.1Q cloud separating the Cisco switches is treated as a single trunk link between the switches. Verify the dynamic VLAN reconfirmation status. In VTP version 1 or 2, if you enter an extended-range VLAN ID when the switch is not in VTP transparent mode, an error message is generated when you exit VLAN configuration mode, and the extended-range VLAN is not created. Verify your entries in the Administrative Mode and the Access Mode VLAN fields of the display. (See the “Creating or Modifying an Ethernet VLAN” section on page 14-8.). the specifications and information regarding the products in this manual are subject to change without notice. To autonegotiate trunking, the interfaces must be in the same VTP domain. To reset the access mode to the default VLAN for the switch, use the no switchport access vlan interface configuration command. Specify the native VLAN for IEEE 802.1Q trunks. Note You must have IP connectivity to the VMPS for dynamic-access ports to work. See the “Configuring a VLAN as an RSPAN VLAN” section on page 28-18. When VTP detects a new VLAN and the VLAN is not in the allowed list for a trunk port, the trunk port does not become a member of the new VLAN. VTP version supports extended-range VLANs in server or transparent move. The switch supports per-VLAN spanning-tree plus (PVST+) or rapid PVST+ with a maximum of 128 spanning-tree instances. VTP exchanges VLAN configuration messages with other switches over trunk links. By VMPS clients periodically reconfirm the VLAN membership information received from the VMPS.You can set the number of minutes after which reconfirmation occurs. (See the “VTP Pruning” section on page 15-6). When VTP detects a newly enabled VLAN and the VLAN is in the allowed list for a trunk port, the trunk port automatically becomes a member of the enabled VLAN. When you delete a VLAN from a switch that is in VTP transparent mode, the VLAN is deleted only on that specific switch stack. Beginning in privileged EXEC mode, follow these steps to confirm the dynamic-access port VLAN membership assignments that the switch has received from the VMPS: Reconfirm dynamic-access port VLAN membership. One trunk port sends or receives all traffic for the VLAN. Note Extended-range VLANs (VLAN IDs 1006 to 4094) are only saved in the VLAN database in VTP version 3. (Optional) Enter the IP address of the switch acting as a secondary VMPS server. Trunk negotiation is managed by the Dynamic Trunking Protocol ( DTP), which is a Point-to-Point Protocol. Any hosts that come online through the port are checked again through the VQP with the VMPS before the port is assigned to a VLAN. Note Stacking is supported only on Catalyst 2960-S switches running the LAN base image. Beginning in privileged EXEC mode, follow these steps to configure the network shown in Figure 14-2.
