gre concentrator

gre

Creates a GRE Concentrator profile for supported ExtremeWireless WiNG controllers.

The GRE Concentrator feature supports GRE tunneling between APs and ExtremeWireless WiNG controllers.

With this feature, an AP acts as GRE initiator and creates wireless client tunnels to an ExtremeWireless WiNG controller that is operating as a GRE concentrator tunnel terminator.

The maximum limits on GRE tunnel terminations for controller platforms are as follows:

PlatformMaximum GRE Tunnels Supported
NX5500512
NX75001000
NX96101024
CX9000Not suppported
VX9000Not suppported

Complete the following tasks to configure GRE tunneling between APs and ExtremeWireless WiNG controllers:

  1. Configure a GRE Concentrator profile for a supported controller.
  2. Configure VLANs for an AP.
    Note

    Note

    GRE Concentrator can terminate GRE tunnels mapped to more than one VLAN. You must configure one Native VLAN that is capable of transmitting untagged (default) or tagged traffic. All other VLANs will transmit tagged traffic. Select the Native VLAN when you configure the GRE tunnel profile in the next step.
  3. Configure the GRE peer-to-peer settings on the AP and try to reach the concentrator using the ping command.

Supported on the following devices:

Syntax

gre concentrator <GRE-CONC-TUNNEL>

Parameters

gre concentrator <GRE-CONC-TUNNEL>
<GRE-CONC-TUNNEL>Specify the GRE concentrator name. If a GRE concentrator profile with the specified name does not exist, it is created.
Note: Only one GRE concentrator profile can be configured for a controller.

Examples

vx9000-AA3AED(config-profile-gre-conc-tunnel)#gre concentrator ?
  GRE-CONC-TUNNEL  Name of the GRE concentrator to be configured (will be
                   created if it does not exist)
vx9000-AA3AED(config-profile-gre-conc-tunnel)#gre concentrator gre-test
vx9000-AA3AED(config-profile-gre-conc-tunnel-gre-concentrator-gre-test)#?
