Nexus 7000 / FEX Jumbo Frame Configuration (only applies to version 6.2 and later) You must instead create a custom QoS policy as the next configuration shows. Note: The Nexus 7000 does not allow you to set FEX MTU with the FPC in Version 6.2 and later. Per-Port Fabric Port Channel (FPC) Configuration (to be configured on the Parent Nexus Switch) interface port-channel136 These changes are automatically pushed down to the FEX in both cases. If the parent switch requires a network-qos policy, then jumbo is set with the QoS policy configuration of the parent switch. For parent switches that allow jumbo on a per-port basis, configure the FEX Fabric Port-channel (FPC). Note: The Nexus 2000 MTU is set with the configuration of jumbo frames on the parent switch. If an invalid value is entered, an error is returned: Nexus(config-if)# mtu 9000ĮRROR: MTU can only be default or system jumbo MTU Nexus 2000 Configuration In order to configure MTU on a per-port basis, this configuration is needed: Nexus(config)# interface ethernet 1/1 Nexus# show running-config all | i jumbomtu L2 ports configured with Jumbo MTU automatically updates to the new value if it is changed.

Nexus 9000: All Nexus 9200 Series switches (includes 92xxx), 9300 Series switches (includes 93xxx), and 9500 Series switchesįor platforms that use Per-Port MTU Configuration L2 ports can use only the System Jumbo MTU configured on the switch or 1500. Neuxs 7000: All Nexus 7000- and 7700 Series switches Service-policy type network-qos jumbo Per-Port MTU Configuration This includes any Cisco Fabric Extender (FEX) ports connected to the switch. In order to configure elevated MTU on these switches, create a network-qos policy or modify a policy that already exists in order to specify the elevated MTU. Nexus 6000: All Nexus 6000 Series switches Only the Nexus 7000, 9000, and certain 3000 models support per-port MTU. Layer 2 MTU is set either through a network Quality of Service (QoS) policy or through configuration of the port itself (on switches that support per-port MTU). Nexus(config-if)# mtu 9216 Layer 2 MTU Configurations Nexus(config-if)# mtu 9216 Configure MTU on a Layer 3 Port Nexus(config)# interface ethernet 1/1 Configure MTU on a Switched Virtual Interface (SVI) Nexus(config)# interface vlan 1 Configure Layer 3 MTU ConfigurationsĪll Layer 3 ports, regardless of platform, are configured on a per-port basis. If your network is live, ensure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration.
