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
High-Gigabit Port Channel Commands
High-Gigabit Ethernet 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 high-Gigabit port channel is uneven.
NOTE: High-Gigabit port channels on the backplane are also referred to as high-Gigabit link
bundles in Z9500 documentation and CLI.
On the Z9500, backplane port channels operate as high-Gigabit 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 Z9500 line cards.
Line-card NPUs are numbered as follows:
