- captured inventory data: name,oper-status,testbed-id,role,model,s/n,rackid,rackunit,mgmt-ip4,ipmi-ip4,new-rackid,new-rackunit,new-mgmt-ip4,new-ipmi-ip4
  - name: CSIT functional server name as tracked in [CSIT testbed specification](https://git.fd.io/csit/tree/docs/lab/testbed_specifications.md), followed by "/" and the actual configured hostname, unless it is the same as CSIT name.
  - oper-status: operational status (up|down|ipmi).
  - testbed-id: CSIT testbed identifier.
  - role: 2n/3n-xxx performance testbed, nomad-client, nomad-server.
    - role exceptions: decommission, repurpose, spare.
  - model: server model.
  - s/n: serial number.
  - mgmt-ip4: current management IPv4 address on management VLAN.
  - ipmi-ip4: current IPMI IPv4 address on LOM VLAN.
  - rackid: new location rack id.
  - rackunit: new location rack unit id.

/**
 * @file
 * @brief Ethernet VLAN Tag Rewrite.
 *
 * VLAN tag rewrite provides the ability to change the VLAN tags on a packet.
 * Existing tags can be popped, new tags can be pushed, and existing tags can
 * be swapped with new tags. The rewrite feature is attached to a subinterface
 * as input and output operations. The input operation is explicitly configured.
 * The output operation is the symmetric opposite and is automatically derived
 * from the input operation.

/*?
 * VLAN tag rewrite provides the ability to change the VLAN tags on a packet.
 * Existing tags can be popped, new tags can be pushed, and existing tags can
 * be swapped with new tags. The rewrite feature is attached to a subinterface
 * as input and output operations. The input operation is explicitly configured.
 * The output operation is the symmetric opposite and is automatically derived
 * from the input operation.
 *
 * <b>POP:</b> For pop operations, the subinterface encapsulation (the vlan
 * tags specified when it was created) must have at least the number of popped
 * tags. e.g. the \"pop 2\" operation would be rejected on a single-vlan interface.
 * The output tag-rewrite operation for pops is to push the specified number of
 * vlan tags onto the packet. The pushed tag values are the ones in the
 * subinterface encapsulation.
 *
 * <b>PUSH:</b> For push operations, the ethertype is also specified. The
 * output tag-rewrite operation for pushes is to pop the same number of tags
 * off the packet. If the packet doesn't have enough tags it is dropped.
 *
 *
 * @cliexpar
 * @parblock
 * By default a subinterface has no tag-rewrite. To return a subinterface to
 * this state use:
 * @cliexcmd{set interface l2 tag-rewrite GigabitEthernet0/8/0.200 disable}
 *
 * To pop vlan tags off packets received from a subinterface, use:
 * @cliexcmd{set interface l2 tag-rewrite GigabitEthernet0/8/0.200 pop 1}
 * @cliexcmd{set interface l2 tag-rewrite GigabitEthernet0/8/0.200 pop 2}
 *
 * To push one or two vlan tags onto packets received from an interface, use:
 * @cliexcmd{set interface l2 tag-rewrite GigabitEthernet0/8/0.200 push dot1q 100}
 * @cliexcmd{set interface l2 tag-rewrite GigabitEthernet0/8/0.200 push dot1ad 100 150}
 *
 * Tags can also be translated, which is basically a combination of a pop and push.
 * @cliexcmd{set interface l2 tag-rewrite GigabitEthernet0/8/0.200 translate 1-1 dot1ad 100}
 * @cliexcmd{set interface l2 tag-rewrite GigabitEthernet0/8/0.200 translate 2-2 dot1ad 100 150}
 * @cliexcmd{set interface l2 tag-rewrite GigabitEthernet0/8/0.200 translate 1-2 dot1q 100}
 * @cliexcmd{set interface l2 tag-rewrite GigabitEthernet0/8/0.200 translate 2-1 dot1q 100 150}
 *
 * To display the VLAN Tag settings, show the associate bridge-domain:
 * @cliexstart{show bridge-domain 200 detail}
