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 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
Example: peGigE
Dell#show port-channel-flow port-channel 111 incoming-interface pegigE
111/0/33
src-mac 00:01:0b:00:00:00 dest-mac 00:01:0b:00:03:00 vlan 111 ether-type
ff:ff
Egress Port information for port-channel 111, for the given flow,is
PeGi 111/0/38.
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 .
The backplane port channels operate as HiGig link bundles to transmit data traffic between line-card and SFM NPUs. There are 10 line-
cards and 2 SFM NPUs. The 6 SFM (spine) NPUs comprise the switch fabric module.
Each line-card has one NPU numbered 0. SFM NPUs are numbered 0 to 1.
Line-card and SFM NPUs use HiGig port channels to transmit data.
• An SFM NPU uses 10 HiGig port channels, one port channel to transmit data to each line-card NPU. Each HiGig port channel in an
SFM NPU consists of three HiGig links.
