Step A. DHCP scope within the native VLAN:
1 IP RFP boots up and obtains an address on the native VLAN.
2 The data VLAN DHCP option 132 directs the IP RFP to go to voice VLAN.
Step B. DHCP scope within the voice VLAN:
1 IP RFP releases the data VLAN address and obtains an address on the voice VLAN and
all other parameters.
The voice VLAN does not have the DHCP option 132, because a IP RFP already on the
voice VLAN does not need to be directed to go there.
2 IP RFP is operational on the voice VLAN.
If a reboot or power cycle occurs, the IP RFP returns to step A.
If an IP RFP cannot obtain an address on the voice VLAN, due to network or DHCP
problems then the IP RFP falls back automatically to untagged frames (native VLAN).
To avoid the DHCP scope within the native VLAN the VLAN ID to be used can be set
permanently via OMC without losing the ability to provide other parameter via DHCP, please
see section 0 Static Local Configuration Of An RFP.
9.10.2 Boot Phase of IP RFPs (Local Configuration)
The PC running the OM Configurator has to be a member of the native VLAN for the 1st
configuration, later on within the voice VLAN set.
If a wrong or unknown VLAN ID is set, you can overwrite or read the configuration using no
VLAN tag on the switch port in the first 6 seconds after the RFP is connected to a power
supply / PoE. After 6 seconds the RFP apply the local configurations and start using the
parameters.
9.11 Installing OMM in Host Mode
In this case the OMM software has to be installed on a PC running with Red Hat© Enterprise
Linux 6 for x86 server. The network parameters with which the OMM works in this mode
depend on this PC’s network configuration.
Once started, OMM works permanently on the PC. In case of fatal error or PC restart, OMM
will restart automatically.
Please note: Check that the versions of the OMM and RFP software on your SIP–DECT
installation are the same. The OMM in host mode is not supported on virtual
machines.
