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
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

<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.
