Configuration Limits


The features supported by the Cisco Nexus 4001I and 4005I Switch Module for IBM BladeCenter Switch have maximum configuration limits. For some of the features, we have verified configurations that support limits less than the maximum. Table 36-1 lists the Cisco verified limits and maximum limits for switches running Cisco NX-OS for the Cisco Nexus 4001I and 4005I Switch Module for IBM BladeCenter.
