Configure Advanced VLAN Features

Use advanced VLAN features to configure the VLAN name, aging time, VLAN operation action, and QoS level. The VLAN Operation Action parameter can be useful for troubleshooting.

You can also configure a DvR Gateway IPv4 address on a VLAN, and enable DvR on it.

Procedure

  1. In the navigation pane, expand Configuration > VLAN.
  2. Select VLANs.
  3. Select the Advanced tab.
  4. Configure the parameters as required by double-clicking fields to make changes.

    You cannot make changes to fields that are dim.

  5. Select Apply.

Advanced Field Descriptions

Use the data in the following table to use the Advanced tab.

Name

Description

Id

Specifies the VLAN ID in the range of 1 to 4059. By default, VLAN IDs 1 to 4059 are configurable and the system reserves VLAN IDs 4060 to 4094 for internal use. On switches that support the vrf-scaling and spbm-config-mode boot configuration flags, if you enable these flags, the system also reserves VLAN IDs 3500 to 3998. VLAN ID 1 is the default VLAN and you cannot create or delete VLAN ID 1.

Name

Specifies the name of the VLAN.

IfIndex

Specifies the logical interface index assigned to the VLAN.

Type

Specifies the type of VLAN:

  • byPort

  • byProtocolId

  • spbm-bvlan

  • private

Isid

Specifies the Service Instance Identifier (I-SID) number assigned to a customer VLAN (C-VLAN). The default value is 0, which indicates that no I-SID is assigned.

Isid Name

Specifies the name of the I-SID.
Origin

Specifies the origin of the VLAN configuration, either manually configured through CLI or SNMP, or dynamically configured through RADIUS VSA or Zero Touch Fabric Configuration.

ProtocolId

Specifies the network protocol for protocol-based VLANs.

If the VLAN type is not protocol-based, a value of None displays in the Basic tab ProtocolId field.

AgingTime

Specifies the timeout period for dynamic VLAN membership. A potential VLAN port is made ACTIVE after it receives a packet that matches the VLAN; if no such packet is received for AgingTime seconds, the port is no longer active. The default is 600.

MacAddress

Specifies the MAC address assigned to the virtual router interface for this VLAN. This field is relevant only after the VLAN is configured for routing. This MAC address is used as the Source MAC in routed frames and ARP replies.

Vlan Operation Action

Performs an operation on the VLAN. The values are:

  • none

  • flushMacFdb: Configures action to flushMacFdb. This action removes the learned MAC addresses from the forwarding database for the selected VLAN.

  • flushArp: Configures action to flushArp. This action removes the ARP entries from the address table for the selected VLAN.

  • flushIp: Configures action to flushIp. This action removes the learned IP addresses from the forwarding table for the selected VLAN.

  • flushDynMemb: Configures action to flushDynMemb. This action removes port members not configured as static from the list of active port members of a policy-based VLAN and removes MAC addresses learned on those ports.

  • all: Configures action to all. This action performs all the supported actions; it does not perform the Snoop-related actions.

The default is none.

Result

Specifies the result code after you perform an action.

NlbMode

Enables or disables Microsoft Network Load Balancing (NLB) operations on the VLAN. The default is disabled.

SpbMulticast

Enables or disables IP Multicast over Fabric Connect. The default is disabled.

SpbPimGatewayMulticast

Enables or disables SPB-PIM Gateway Multicast on a VLAN. The default is disabled.

RmonEnable

Enables or disables Remote Monitoring (RMON) on the interface. The default is disabled.

Ipv6FhsSnoopDhcpEnable

Enables or disables IPv6 dhcp snooping on a VLAN. The default is disabled.

Ipv6FhsNDInspectionEnable

Enables or disables neighbor discovery (ND) inspection on a VLAN. The default is disabled.

DvrEnable

Enables or disables Distributed Virtual Routing (DvR) on a VLAN that is configured on the DvR Controller. The default is disabled.

Note:

You must enable DvR on every VLAN that is configured on a DvR Controller.

DvrGwIpv4Addr

Specifies the DvR gateway IPv4 address for a VLAN.

Important:

Ensure that you configure the same gateway IPv4 address on all Controllers in the DvR domain that belong to a VLAN.

DvrGwIpv4OneIp

Enables or disables the DvR One IP for a VLAN. The default is disabled (false).

DvrVrrpElection

Identifies the DvR VLAN, and associated I-SID, to become the primary Virtual Router Redundancy Protocol (VRRP) router through the election process.

You can identify only one VLAN for election per DvR Controller.

By default, no VLAN is configured as the DvR VRRP election VLAN.

MvpnIsidValue

Configures the MVPN I-SID value for the VLAN.

MvpnIsidStatus

Identifies the MVPN I-SID status.

  • static—VRF was created by configuring an MVPN I-SID on a VLAN through CLI and EDM
  • dynamic—VRF was created by configuring an MVPN I-SID on a VLAN through RADIUS
  • notConfigured—MVPN I-SID is not configured on a VLAN.
MvpnIsidOffset

Allows you to add an offset parameter to the MVPN I-SID. This is an optional value and the range is 0-511.
