Note the following during the configuration:
1) When the apply poe-profile command is used to apply a PoE profile to a port, some PoE features in
the PoE profile can be applied successfully while some cannot. PoE profiles are applied to Switch
4500 according to the following rules:
z
When the
apply poe-profile
command is used to apply a PoE profile to a port, the PoE profile is
applied successfully only if one PoE feature in the PoE profile is applied properly. When the
display current-configuration
command is used for query, it is displayed that the PoE profile is
applied properly to the port.
z
If one or more features in the PoE profile are not applied properly on a port, the switch will prompt
explicitly which PoE features in the PoE profile are not applied properly on which ports.
z
The
display current-configuration
command can be used to query which PoE profile is applied to
a port. However, the command cannot be used to query which PoE features in a PoE profiles are
applied successfully.
2) PoE profile configuration is a global configuration, and applies synchronously in the Expandable
Resilient Networking (XRN) system.
3) Combination of Unit creates a new Fabric. In the newly created Fabric, the PoE profile
configuration of the Unit with the smallest Unit ID number will become the PoE profile configuration
for the Fabric currently in use.
4) Split of Fabric results in many new Fabrics. In each newly created Fabric, the PoE profile
configuration of each Unit remains the same as it was before the split.
