Configuring Vlan Qos; Configuring Or Changing The Interface Qos Tcam Limit - Cisco Nexus 5000 NX-OS Service Configuration Manual

Configuring QoS on VLANs
• Remove all interface QoS policies before changing the interface QoS limit.
• Acllogs can only support logging levels of 3 or later.
• We support only logging denials on the ACL, permits will not be logged.
• Only one log message will be displayed until the flow stops and the rest is displayed later.

Configuring VLAN QoS

Configuring or Changing the Interface QoS TCAM Limit

To configure the interface_qos_limit to a specific number, the QoS region of the TCAMs in all of the ASICs
cannot have any interfaces policies configured beyond the offset of that number. For example, to configure
the interface_qos_limit to 1000, the QoS regions of the TCAMs in all of the ASICs cannot have any interface
policies configured beyond offset 1000.

Configuring VLAN QoS

Purpose
Enters global configuration mode.
Configures the interface QoS TCAM limit. The
tcam-size range is from 7 to 446 entries.
Displays the limits of the QoS TCAMs.
(Optional)
Saves the change persistently through reboots and
restarts by copying the running configuration to
the startup configuration.
