Configuring the Internal VLAN Range
RUGGEDCOM ROX II creates and utilizes internal VLANs for internal functions. To provide RUGGEDCOM ROX II with
a pool of VLAN IDs to pull from when creating internal VLANs, a range of VLAN IDs must be reserved.
CAUTION!
Configuration hazard – risk of data loss. If the range-start or range-end values are changed in a way
that invalidates any configured internal VLANs, the configurations defined for the affected VLANs will
be lost upon repositioning.
IMPORTANT!
VLAN IDs reserved for internal VLANs should not be used by the network.
NOTE
Changing the range-end value repositions the matching serial VLAN. However, the matching serial
VLAN is not affected when the range-start value is changed.
NOTE
If no internal VLANs are available when a switched Ethernet or trunk port is configured, the range is
automatically extended so a unique value can be assigned.
NOTE
Routable Ethernet ports and trunks cannot be configured if internal VLANS are not enabled.
