This field

Displays

Management VRF name Displays the configured management VRF name.

Management Application Displays the management application names.

Rx Drop Pkts

Displays the number of packets dropped in the inbound traffic.

Tx Drop Pkts

Displays the number of packets dropped in the outbound traffic.

TCP Connection rejects

Displays the number of TCP connections per application rejected due to management
VRF validation.

Make sure that the management VRF is configured before executing the show management-vrf
command. If not, the system will display the following error message.

Error - Management VRF is not configured.

To clear the management VRF rejection statistics, enter the following command.

device(config)# clear management-vrf-stats

Configuring sFlow with Multi-VRFs

sFlow is a traffic monitoring protocol that supports VRFs. sFlow provides traffic sampling on configured
ports based on sample rate and port information to a collector. By default, sFlow uses the management
VRF to send the samples to the collector. See the section

Configuring Management VRFs

on page 645

for information on management VRFs. If no management VRF is configured, sFlow uses the default
VRF, and this default VRF ID will be assigned to any configured collector that does not have a user-
included VRF.

Collectors can be added and exist per VRF so that collectors can be spread out across different VRFs.
The sFlow forwarding port can belong to a non-default VRF, and captured sFlow packets will have
correct sample routing next hop information.

sFlow forwarding ports can come from ports belonging to any VRF. The port does not have to be in the
same VRF as the collector. sFlow collects packets from all sFlow forwarding ports, even if they do not
belong to a VRF, compiles the packets into the sFlow samples, and sends the samples to the particular
collector with no filtering for VRF membership. For counter samples, sample statistics from each port
are sent to each collector specified, even if the port and collector do not belong to a VRF instance.
