Configuring Fabric Attach

An ExtremeXOS Fabric Attach device automatically detects and exchanges information with attached Fabric Attach devices, except that a proxy does not exchange information with another proxy).

The following are optional user-configurable items:
  • Static VLAN/NSI assignments
  • Fabric Attach authentication on either a proxy or server
  • Management VLAN (Fabric Attach server only)
  • Uplink port (Fabric Attach proxy only)

Static VLAN/NSI Assignments

You explicitly create static Fabric Attach VLANs. Static VLANs can be mapped to a Network Service Identifier (NSI) or Individual Service Identifier (ISID).

To map a VLAN to an NSI/ISID, use the following command:

configure [{vlan} vlan_name |vlan vlan_id] add [nsi nsi | isid isid]

Mappings created with this command are persistent across reboots, whereas mappings by Fabric Attach clients and mappings requested by RADIUS/Policy/NetLogin are not persistent.
Note

Note

While it is possible to configure an NSI mapping using the command configure virtual-network vn_name vxlan vni [ vni | none], it is not recommended to do so when using Fabric Attach.

To unmap a VLAN from an NSI/ISID, use the following command:

configure [{vlan} vlan_name |vlan vlan_id] delete [nsi nsi | isid isid]

To display VLAN to NSI/ISID information, use the following command:

show [{vlan} vlan_name | vlan {vlan_id}] fabric attach assignments

Fabric Attach Authentication

To set up authentication, use the following command:

configure fabric attach ports [port_list | all] authentication [ disable | enable | key {key | default | encrypted encrypted_key}]

Note

Note

When Fabric Attach authentication is configured on ports that are part of an MLAG (Multi-switch Link Aggregation Group), all ports on that MLAG must have the same Fabric Attach authentication configuration.

To view authentication information, use the following command:

show fabric attach ports [port_list | all] authentication {detail}

Standalone Proxy/Uplink Port

If there is no Fabric Attach-capable server available, configuring an uplink makes the device a standalone proxy. This works like a proxy, but without having discovered a Fabric Attach server. The uplink port is treated as the server port.

To enable standalone proxy mode and specify the uplink port, use the following command using the port keyword:

configure fabric attach uplink [port | none]

To disable standalone proxy mode, use the following command using the none keyword:

configure fabric attach uplink [port | none]

Management VLAN

To specify the VLAN advertised to Fabric Attach clients for them to use as the management VLAN, use the following command:

configure fabric attach management-vlan [vlan_id | vlan_name | untagged | none]

Viewing Fabric Attach Elements

To display a list of known fabric attach elements information, use the following command:

show {[vlan} vlan_name | vlan {vlan_id}]} fabric attach [agent} | assignments | {ports [all | port_list]} |elements | statistics]
