gre concentrator

gre

Creates a GRE Concentrator profile for supported ExtremeWireless WiNG controllers.

This feature allows an ExtremeWireless WiNG controller to operate as a terminator for GRE tunnels configured on ExtremeCloud IQ managed Universal APs running IQ Engine OS. GRE Concentrator supports up to 1000 GRE tunnel terminations.

Note

Note

You must disable all legacy ExtremeWireless WiNG adoption to enable the controller to operate only as a GRE Concentrator. After you create a GRE tunnel concentrator profile, configure the DHCP Server Policy to create dhcp pools for the allowed VLANs defined in the GRE tunnel concentrator profile.

Example:

MD-DC7510(config)#dhcp-server-policy greconc
MD-DC7510(config-dhcp-server-policy-greconc)#show context
dhcp-server-policy greconc
  option  AP-Adopt 191  ascii
  dhcp-pool VLAN97
    network  10.97.0.0/24
    address range 10.97.0.100  10.97.0.150
    lease 0 5
    default-router  10.97.0.1
    dns-server   4.2.2.2
    respond-via-unicast
 dhcp-pool VLAN98
    network  10.98.0.0/24
    address range 10.98.0.100  10.98.0.150
    default-router  10.98.0.1
    dns-server   4.2.2.2
    respond-via-unicast

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)#?
GRE Concentrator Tunnel Mode commands:
  allowed-vlan  VLANs to tunnel
  idle-timeout  GRE tunnel inactivity timeout
  no            Negate a command or set its defaults

Related Commands

allowed-vlan Specifies the VLANs that are allowed to terminate GRE tunnels on the GRE concentrator
