Release 4.0(1a)N1(1) Upgrade and Downgrade Issues
The following table describes the changes to the priority flow control configuration.
The following table describes the changes to the syntax of the Ethernet load-balancing commands.
When an Ethernet interface joins a EtherChannel, the following interface level parameters are disabled:
bandwidth Set bandwidth informational parameter
delay Specify interface throughput delay
duplex Enter the port duplex mode
flowcontrol Configure interface flowcontrol
ip Configure IP features
ipv6 Configure IPv6 features
mac MAC configuration commands
priority-flow-control Configure interface priority-flowcontrol
service-policy Configure QoS service policy
spanning-tree Spanning Tree Subsystem
speed Enter the port speed
storm-control Configure Interface storm control

Priority flow control is an interface level configuration. This CLI option is used to
override results of DCBX negotiation. Priority flow control function is not aware of
the EtherChannel. It strictly follows a per-member port configuration.
4.0(1a)N1(1) No configuration allowed on member ports. All member ports follow the
configuration on the EtherChannel.
Upgrade If a member port has modified priority flow control configuration and the
EtherChannel is explicitly configured, then port configuration is lost. The
EtherChannel has default priority flow control configuration.
Downgrade This capability needs to be reconfigured after the downgrade. Otherwise, the priority
flow control configuration on the EtherChannel will be lost.

The following command is used to set the load-balancing method in a channel-group
bundle:
switch(config)# port-channel load-balance ethernet source-destination-?
source-destination-ip Source & Destination IP address
source-destination-mac Source & Destination MAC address
source-destination-port Source & Destination TCP/UDP port
Note The keyword source-destination is used in this release.
4.0(1a)N1(1) The following command is used to set the load-balancing method in a channel-group
bundle:
switch(config)# port-channel load-balance ethernet source-dest-?
source-dest-ip Source & Destination IP address
source-dest-mac Source & Destination MAC address
source-dest-port Source & Destination TCP/UDP port
Note The keyword source-dest is used in this release.
Upgrade The load-balancing configuration is lost.
Downgrade This capability needs to be reconfigured after the downgrade. Otherwise, the
load-balancing configuration on the EtherChannel will be lost.
