How to Enable VLAN Trunking on Avi Service Engine Running on ESX
Overview
This article discusses configuration changes required to enable VLAN trunking on Avi Service Engines running on ESX in no -access mode.
Enabling VLAN Tagging on Avi Service Engine
Follow the below steps to enable VLAN trunking on Avi Service Engines.
-
Login to Avi UI and navigate to Infrastructure > Service Engines. Select the desired Service Engines and click on the edit option.
-
Click on Create VLAN Interface as shown below.
-
Provide the required details as shown below and click on Save. Name and Parent Interface are the mandatory fields.
In the above example, VLAN trunking is enabled on the Ethernet interface 1 with VLAN 137.
You can now place the virtual service on Avi Service Engine using the usual way.
To create virtual service on Avi Vantage, refer to Virtual Services.
Enabling VLAN Tagging on ESX
To enable support for VLAN trunking to the Service Engine virtual machine in a vSphere environment, refer to the Virtual Guest Tagging (VGT) mode described in VLAN Configuration guide.
Configuring vLAN Interface
Starting with Avi Vantage version 20.1.3, the number of vLAN interfaces allowed to be configured on a SE is increased from 224 to 1000 (this feature is supported only in VMware no-access mode). As the number of vLAN interfaces increases, the memory usage increases significantly. The additional memory required for configuring 1000 vLAN interfaces is approximately 550MB. If there are configurations such as virtual services on those interfaces, then more memory is required.
If the memory runs low when you add a vLAN interface, the configuration is accepted but the interface is put into fault state. You can confirm this by using show serviceengine < > vnicdb command and check if there is a fault entry for the concerned interface.
The following is the sample output with fault entry:
| Field | Value |
|---|---|
| vnic[2] | |
| if_name | avi_eth2.999 |
| linux_name | eth2.999 |
| mac_address | 00:50:56:81:2f:ec |
| pci_id | PCI-eth2.999 |
| mtu | 1496 |
| dhcp_enabled | True |
| enabled | True |
| connected | True |
| network_uuid | Unknown |
| nw[1] | |
| ip | 100.3.231.0/24 |
| mode | STATIC |
| nw[2] | |
| ip | fe80::250:56ff:fe81:2fec/64 |
| mode | DHCP |
| is_mgmt | False |
| is_complete | True |
| avi_internal_network | False |
| enabled_flag | True |
| running_flag | True |
| pushed_to_dataplane | False |
| consumed_by_dataplane | False |
| pushed_to_controller | False |
| can_se_dp_takeover | True |
| vrf_ref | global |
| vrf_id | 1 |
| ip6_autocfg_enabled | True |
| fault | |
| uuid | 00:50:56:81:2f:ec-eth2.999 |
The following are the reason and recommendation details:
| reason | Insufficient memory to apply configuration |
| recommendation | Free up resources on this SE[se-00505681a639] and then do configure and save |
Note: 550MB memory is required to configure 1000 vLAN interfaces. If there are configurations such as virtual services on those interfaces, then more memory is required.
