(01:80:C2:00:00:0E) - if communication is via Ethernet the LV node does not
know the MAC of the MV node. The IFCP petitions are performed in the follo-
wing steps:
쎲
Step 1:
An IFCP request is made without VLANs and waits for a response;
쎲
Step 2:
It then switches to VLAN mode and makes an IFCP request using tag
#1 (reserved in the Wisconsin network) and waits for a response;
쎲
Step 3:
Returns to Step1.
When a node receives a packet with this IFCP MAC, the packet is sent to the FW.
In transmission, this request is forwarded to all active interfaces.
Finally it will connect to a node that will transfer the translation table. The dLAN
200 DSpro adapter switches automatically to use/not use VLANs with the same
configuration as the node sending the translation table.
In this way all dLAN 200 DSpro adapters configure themselves to use/not use
VLANs. This avoids having to write the use or non-use of VLANs in the NVRAM
of all dLAN 200 DSpro adapters, a circumstance that can be extremely frustra-
ting if an operator wants to change the entire network to use VLANs.
A dLAN 200 DSpro adapter must not perform IFCP (Autoconfiguration-noIFCP
Boot) in the NVRAM in the following two cases:
쎲
If it is the first node of the network (directly connected to the backbone);
쎲
If it is going to receive the translation table in the autoconfiguration file.
In the first instance, this node will transfer the translation table (included in the
autoconfiguration file) to other dLAN 200 DSpro adapters when requested, but
in this case there is no other dLAN 200 DSpro adapter from which to request this
information because it will be the first node to know it.
To avoid using IFCP in the boot process, two methods are available:
쐃
Using the DHCP server (must be accessible through VLAN #1 or without
VLAN), the IFCP protocol can be skipped. In the DHCP reply, the server can
supply the dLAN 200 DSpro adapter with the management VLAN (in the
event the dLAN 200 DSpro adapter boost in VLAN mode) or tell the dLAN
200 DSpro adapter not to use VLANs;
쐇
Write a byte in the NVRAM using console. In this type of boot the dLAN 200
DSpro adapter reads its NVRAM to check if it has to use/not use VLANs and
the Management VLAN (if needed), requests an IP from the DHCP server and
finally receives its autoconfiguration file via TFTP.
