If multichassis EtherChannel trunk (MCT) is enabled and the traffic flows from a virtual port channel
(vPC) peer link, the output displays “Outgoing port id (vPC peer-link traffic)”.
To get accurate results, you must do the following:
•
(For unicast frames) Provide the destination MAC address (dst-mac) and the VLAN for hardware hashing
(vlan). When the destination MAC address is not provided, hardware hashing is assumed.
•
(For multicast frames) For IP multicast, provide either the destination IP address (dst-ip) or destination
MAC address (dst-mac) with the VLAN for hardware hashing (vlan). For non-ip multicast, provide the
destination MAC address with the VLAN for hardware hashing.
•
(For broadcast frames) Provide the destination MAC address (dst-mac) and the VLAN for hardware
hashing (vlan).
Examples
This example shows how to display the port channel load-balancing information:
switch# show port-channel load-balance
Port Channel Load-Balancing Configuration:
System: source-dest-ip
Port Channel Load-Balancing Addresses Used Per-Protocol:
Non-IP: source-dest-mac
IP: source-dest-ip source-dest-mac
switch#
The following table describes the fields shown in the display.
Table 4: show port-channel load-balance Field Descriptions
DescriptionField
The load-balancing method configured on the switch.System
The field that will be used to calculate the hash value
for non-IP traffic.
Non-IP
The fileds used for IPv4 and IPv6 traffic.IP
This example shows how to display the port channel load-balancing information when hardware hashing is
not used:
switch# show port-channel load-balance forwarding-path interface port-channel 5 vlan 3
dst-ip 192.168.2.37
Missing params will be substituted by 0's.
Load-balance Algorithm on FEX: source-dest-ip
crc8_hash: Not Used Outgoing port id: Ethernet133/1/3
Param(s) used to calculate load-balance (Unknown unicast, multicast and broadcas
t packets):
dst-mac: 0000.0000.0000
vlan id: 3
