Release 4.0(1a)N1(1a) Upgrade and Downgrade Issues Send documentation comments to [email protected] The following table describes the changes to the interface level QoS service policy, 4.0(0)-based releases 4.0(1a)N1(1a) Upgrade Downgrade Interface level QoS service policy is not aware of the EtherChannel. QoS strictly follows a per-member port configuration. The only service policy supported on the interface level is egress queue scheduling. No configuration is allowed on member ports. All member ports follow the configuration on the EtherChannel. If any member port has a modified egress scheduling policy and the EtherChannel is explicitly configured, then the egress scheduling configuration for the port is lost. A EtherChannel has a default egress scheduling policy. This capability needs to be reconfigured after the downgrade. Otherwise, egress queue scheduling configuration on the EtherChannel will be lost after the downgrade. The following table describes the changes to the priority flow control configuration. 4.0(0)-based releases 4.0(1a)N1(1a) Upgrade Downgrade Priority flow control is an interface level configuration.
