exhausted. If the VLAN ACL creation fails, it results in VLAN creation failure. As a result, there cannot be more than 256 VLANs in Fabric mode. When a VLAN is created with the uplink ports, a traffic class such as gold, silver, or platinum is assigned to the traffic on the VLAN. On receiving the configuration from GUI through DNV, the Fabric agent creates a classmap of type qos with the name CM which matches the same . For example when vlanid 100 with a traffic class of type 4 the classmap created will be: classmap type qos CM100 match vlan 100 A single policymap is created to hold all the VLAN classmaps and its applied at the system qos level which gets applied to all the interfaces. policymap type qos PM_VLAN class CM100 set qos-group 4 Any addition, deletion, or modification to the VLAN or the traffic class happens within the same policymap. In the NPU, each classmap maps to an ACL entry in the L2QOS region matching the vlanid in the classmap. Constraints VLAN scaling is limited to the Fabric mode. Currently Dynamic ARP Inspection (DAI) uses the vlan-group id. NAS implicitly programs the VLAN-group id in the Vlan table. But DAI feature is not enabled in Fabric mode. Use of vlan-group id is limited only to applications which require grouping for the purpose of using ACLs. VLAN commands description (VLAN) Adds a description to the selected VLAN. Syntax description description Parameters description - Enter a text string to identify the VLAN. A maximum of 80 characters. Default Not configured Command Mode INTERFACE-VLAN Usage Information None Example OS10(conf-if-vlan)# description vlan3 Supported Releases 10.2.0E or later interface vlan Creates a VLAN interface. Syntax interface vlan vlan-id Parameters vlan-id - Enter the VLAN ID number, from 1 to 4093. Default VLAN 1 Command Mode CONFIGURATION Usage Information FTP, TFTP, MAC ACLs, and SNMP operations are not supported. IP ACLs are supported on VLANs only. The no version of this command deletes the interface. NOTE: In SmartFabric Services mode, creation of VLAN is disabled. 498 Layer 2
