Verifying The Load-Balancing Outgoing Port Id - Cisco Nexus 3548 Configuration Manual

Configuring Port Channels
Command
show port-channel load-balance

Verifying the Load-Balancing Outgoing Port ID

Command Guidelines
The show port-channel load-balance command allows you to verify which ports a given frame is hashed to
on a port channel. You need to specify the VLAN and the destination MAC in order to get accurate results.
Note
Certain traffic flows are not subject to hashing such as when there is a single port in a port-channel.
Note
In warp mode, the output contains two destination ports: one when there is no match in the warp table and
one when there is a match in the warp table. A Layer 2 port match means that the source and destination MAC
addresses are learned in the MAC table whereas a Layer 3 port match means the IP address is resolved.
To display the load-balancing outgoing port ID, perform one of the tasks:
Command
switch# show port-channel load-balance forwarding-path interface
port-channel port-channel-id src-interface source-interface vlan vlan-id
dst-ip src-ip dst-mac src-mac l4-src-port port-id l4-dst-port port-id
ether-type ether-type ip-proto ip-proto
Example
This example shows how to display the load balancing outgoing port ID:
switch# show port-channel load-balance forwarding-path interface port-channel 10 vlan 1
dst-ip 1.225.225.225 src-ip 1.1.10.10 src-mac aa:bb:cc:dd:ee:ff
l4-src-port 0 l4-dst-port 1
Missing params will be substituted by 0's. Load-balance Algorithm on switch: source-dest-port
crc8_hash:204 Outgoing port id: Ethernet 1/1 Param(s) used to calculate load balance:
dst-port: 0
src-port: 0
dst-ip: 1.225.225.225
src-ip: 1.1.10.10
dst-mac: 0000.0000.0000
src-mac: aabb.ccdd.eeff
