Table 2-36 VLAN Configuration Rules
Configuration Rule
VTP v2 mode is enabled, and you
are configuring a TrCRF VLAN
media type.
Specify a parent VLAN ID of a TrBRF that already exists in the
database.
Specify a ring number. Do not leave this field blank.
Specify unique ring numbers when TrCRF VLANs have the same
parent VLAN ID. Only one backup concentrator relay function
(CRF) can be enabled.
VTP v2 mode is enabled, and you
are configuring VLANs other than
TrCRF media type.
Do not specify a backup CRF.
