Manager Option
The server may send IPmux-1/1E a Manager configuration via the DHCP option
field:
• Manager IP - Option 200 (type IP Address)
• VLAN ID - Option 201 (type long)
• VLAN Priority - Option 202 (type byte).
When IPmux-1/1E requests a Manager configuration from the server, there may be
many replies. The device accepts the offer that includes a Manager Option.
If the reply does not include a Manager Option, IPmux-1/1E waits three seconds
for another reply from the server. If no replies have Manager Option, the device
accepts the first offer.
