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).
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]
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 fabric attach {{vlan} | {vlan} vlan_name | vlan vlan_id} assignments
If the VLAN/NSI mappings of type offset is present, then the offset NSI mappings are given the least precedence to be sent to the server for approval regardless of the time the mappings were created.
Beginning with version 33.1.1, you can associate tagged VLANs to be mapped with a NSI value using static NSI offset configuration. When the NSI offset value is configured, any tagged VLAN that does not have a NSI associated will be applied with a NSI value, which is the sum of the configured NSI offset value and VLAN ID.
The NSI offset applied to a VLAN will be removed if an NSI of higher precedence is applied to the VLAN.
Use the following command to configure the NSI offset value:
configure fabric attach isid-nsi-offset isid_nsi_offset
Use the following command to view configured NSI offset information:
show fabric attach {{vlan} | {vlan} vlan_name | vlan vlan_id} assignments
Use the following command to unconfigure the NSI offset value:
configure fabric attach isid-nsi-offset isid_nsi_offset none
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
When Fabric Attach authentication is configured on ports that are part of an This command is available on all Universal switches supported in this document., 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}
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]
configure fabric attach ports [port_list | all] enable | disable]
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 | forward [on | off] ]
configure fabric attach management-vlan ports [port_list | all] forward [on | off]
The specified VLAN configuration on the Fabric Attach server is restricted to only tagged VLANs.
Zero Touch Server enhances FA by allowing a management VLAN to be automatically propagated to FA proxy and FA clients. FA proxy and FA clients use the VLAN to obtain an IP address via Dynamic Host Configuration Protocol (DHCP) and connect to a management device.
To display known fabric attach statistics information, use the following command:
Note
To clear these statistics, use the clear counters command.To display known fabric attach elements (neighbors) information, use the following command:
show fabric attach elements
To display known fabric attach assignments (mappings) information, use the following command:
show fabric attach {{vlan} | {vlan} vlan_name | vlan vlan_id} assignments
To display known fabric attach agent information, use the following command:
show fabric attach agent
To display known Fabric Attach authentication information, use the following command:
show fabric attach ports [port_list | all] authentication {detail}
