Usage
Information Because this command calculates based on a Layer 2 hash algorithm, use this
command to display flows for switched Layer 2 packets, not for routed packets
(use the show ip flow command to display routed packets).
The show port-channel-flow command returns the egress port identification
in a given port-channel if a valid flow is entered. A mismatched flow error occurs if
MAC-based hashing is configured for a Layer 2 interface and you are trying to
display a Layer 3 flow.
The output displays three entries:
• Egress port for unfragmented packets.
• In the event of fragmented packets, the egress port of the first fragment.
• In the event of fragmented packets, the egress port of the subsequent
fragments.
NOTE: In the show port channel flow command output, the egress port
for an unknown unicast, multicast, or broadcast traffic is not displayed.
The following example shows the show port-channel-flow outgoing-port-
channel number incoming-interface interface source-mac address
destination-mac address
• Load-balance is configured for MAC
• Load-balance is configured for IP 4-tuple/2-tuple
• A non-IP payload is going out of Layer 2 LAG interface that is a member of
VLAN with an IP address
Example Dell#show port-channel-flow outgoing-port-channel 1 incoming-
interface te 2/0
source-mac 00:00:50:00:00:00 destination-mac 00:00:a0:00:00:00
Egress Port for port-channel 1, for the given flow, is Te
2/1
HiGig Port Channel Commands
High-Gigabit Ethernet (HiGig) port channels are used to transmit data between internal backplane ports
on line-card (leaf) and switch fabric module (SFM - spine) network processing units (NPUs). You can
configure an SNMP trap to be generated when traffic distribution in a HiGig port channel is uneven.
NOTE: HiGig port channels on the backplane are also referred to as HiGig link bundles in
C9000documentation and CLI.
On the C9000, backplane port channels operate as HiGig link bundles to transmit data traffic between
line-card and SFM NPUs. There are 11 line-card and 6 SFM NPUs. The 6 SFM (spine) NPUs comprise the
switch fabric module; the 11 line-card (leaf) NPUs are used across three C9000line cards.
Line-card NPUs are numbered as follows:
