Fabric Attach Configuration
Fabric Attach Server – VSP 4000, VSP 8000 or VSP 7200
Fabric Attach (FA) is globally enabled by default and must be enabled on a port or MLT interface. By enable
FA on a port or MLT, this will in turn enable LLDP on this interface and send out both FA TLVs and standard
LLDP TLVs. Also, authentication is enabled by default.
config terminal
interface gigabitEthernet <slot/port>
fa
fa enable
exit
interface mlt <1-512>
fa
fa enable
exit
Fabric Attach / Zero Touch – FA Server
On the FA server, a FA port can be configured with the management VLAN using an ISID and VLAN ID
value (c-vid). The c-vid is optional is and if not specified, then the management traffic will be untagged. The
ISID is mandatory and is required for a network wide L2VSN. The FA server will announce this information
in FA LLDP messages where only the management VLAN ID is announced as the ISID is not required. For
untagged management, a VLAN ID of 4095 is announced.
config terminal
interface gigabitEthernet <slot/port>
fa
fa enable
fa management i-sid <1-16777215> c-vid <1-4094>
exit
interface mlt <1-512>
fa
fa enable
fa management i-sid <1-16777215> c-vid <1-4094>
exit
Fabric Attach Proxy or Proxy Standalone – ERS 4800 or ERS 5900
By default, Fabric Attach (FA) Proxy is globally enabled and all ports are enabled with LLDP. In regards to
the ERS 4800, if it is running the standard image, you must disable FA message-authentication on the FA
Server. FA message-authentication is only possible with the secure image for the ERS 4800. VLAN 1
membership must also be removed from all ports or at least the ports used for FA as FA will not otherwise
remove it. If an MLT is used as the uplink to the FA server, then one must create the MLT and, only if the
desired mode is Standalone Proxy, assign the MLT number as the FA trunk.
If the management VLAN is provisioned on the FA Server, this will be learned by the FA Proxy switch which
in turn will attempt to get a management IP address via DHCP on it. The management VLAN ID will also
be passed on to the FA Client, i.e. a WLAN 9100, via FA LLDP messages if used in the solution.
