These ports internally with VLAN numbers starting with 1025.

From vlan-config mode, you can manage the parameters of theįor Catalyst 6000 series switches with FlexWAN cards, the system identifies Toĭo this, enter the vlan vlan-id command to move to VLANs in global configuration mode if the switch is in VTP transparent mode. For CatalystĦ0 switches running Supervisor IOS 12.1(8a) and above, you can create For IOS switches, VLANs are created in vlan database mode. The name for a range of VLANs, however, because each VLAN is to have a unique For COS youĬan specify a range of VLANs in the vlan-id section you cannot configure The vlan-id specifies the VLAN by number. For information on Token Ring or FDDI VLANs, refer to Token Ring and FDDI VLAN configuration and parameters have not been included in However, most of these deal with the configuration of FDDI and Token Ring VLANs.īecause these are not widely used topologies, the options and descriptions of Many other options are available during the VLAN configuration command Ports in a suspended VLAN will be suspended and not allowed to forward traffic. Used to specify whether the state of the VLAN is active or suspended. The MTU can extend up to 1500įor Ethernet, but beyond for Token Ring or FDDI. The maximum transmission unit (packet size, in bytes) that the VLAN can use To VLAN00XXX, where xxx is the VLAN number. Table 6-1Ĝonfigurable VLAN ParametersĪ description of the VLAN up to 32 characters. For Ethernet VLANs, you can also configure the standard VLANs are created using the set vlanĬommand for COS devices or with the vlan command in vlan database Items configured deal with options, such as private VLANs, which are discussed Many options are valid only for FDDI and Token Ring VLANs. When you create a VLAN, you have many options toĬonsider.
#Configure vlans cisco switch software
The extended range consists of VLANs 1025 to 4096.Įxtended VLANs are currently supported only on switches running COS software The standard range consists of VLANs 1 to 1000. After doing so, you can administer the local VTP database. With the introduction of COS version 7.1.1, an option nowĮxists to disable VTP completely. The global configuration command vtp mode transparent is not available VTP is explained in detail in section "6-4: VLAN Trunking You must first either configure VTP with a domain name or disable VTP on the Switches as a default to make administration of VLANs easier. However, Cisco has set it up to act as a conduit for VLAN configuration between VTP is a protocol used by Cisco switches to maintain a consistent databaseīetween switches for trunking purposes. To create a VLAN, use the following steps. When a VLAN is created, you canĪlso give it certain attributes such as a VLAN name, VLAN type, and its VLANs are createdīy number, and there are two ranges of usable VLAN numbers (normal rangeġ≡000 and extended range 1025≤096). If a VLAN is not known to a switch, that switchĬannot transfer traffic across any of its ports for that VLAN. Use of a Layer 3 device for communications. VLANs are created on Layer 2 switches to control broadcasts and enforce the Several VLANs are reserved, and some can be used for internal purposes VLANs have a variety of configurable parameters, including name, type, Cisco switches have two ranges of VLANs, the normal range and VLANs are assigned numbers for identification within and between VLANs are defined on a switch in an internal database known as the VLANs are broadcast domains defined within switches to allowĬontrol of broadcast, multicast, unicast, and unknown unicast within a Layer 2
