Well, they are quite different. The example below has two 10 Gbps ports in a port channel, though I typically configure four ports if I know they will be available. Can i just link the Nexus 7000 like the following? Step 5 Optional switch config copy running-config startup-config Optional Saves this configuration change. So if your design is correct, there are no objections for disabling spanning-tree on those interfaces. Each Nexus will be connected via 20Gb port channel, all servers connect to the Nexus switches via 1Gb links.
These can be overriden per interface. Usage Guidelines This command does not require a license. Now we need to move our CoS 2 traffic to queue 2 and I have only one problem. Appears issue is general Cisco license site problem. Step 5 Optional switch config copy running-config startup-config Optional Saves this configuration change.
Optional show interface if-range 15. Also the queue sizes can be tweaked according to the requirement. Values can range from 0 to 7. You can specify multiple match criteria, you can choose to not match on a particular criterion, or you can determine the traffic class by matching any or all criteria. Are we loss Vpc peer link between both nexus 7 K? For the latest caveats and feature information, see the Bug Search Tool at and the release notes for your software release. Here's what the class-map confiuration looks like: class-map type queuing match-any 1p3q4t-out-pq1 Description: Classifier for egress priority queue of type 1p3q4t match cos 5-7 class-map type queuing match-any 1p3q4t-out-q2 Description: Classifier for egress queue 2 of type 1p3q4t class-map type queuing match-any 1p3q4t-out-q3 Description: Classifier for egress queue 3 of type 1p3q4t class-map type queuing match-any 1p3q4t-out-q-default Description: Classifier for egress default queue of type 1p3q4t match cos 0-4 I just need to figure out how to match CoS 2 under class-map type queuing match-any 1p3q4t-out-q2. You configure the device to take a specific action on the specified classified traffic, such as policing or marking down, or other actions.
Step 5 Optional switch config copy running-config startup-config Optional Saves this configuration change. Setup configures only enough connectivity for management of the system. Related Commands Command Description show class-map Displays class maps. When you configure match all for a QoS class map by entering the class-map type qos match-all command, the match-all option does not work. Values can range from 1 to 9198. I try to do this whether the switches are for internal use or for a customer. Specifies the extended burst rate.
For the latest caveats and feature information, see the Bug Search Tool at and the release notes for your software release. Command: show running-config interface vfc101! Example 8-14 walks through this process. Defaults Thresholds are in packets by default. Values can range from 0 to 63. Requirement There are no specific requirements for this document. Jan 29, 2012 I have a pair of Nexus 7K's running 5.
If you configure shaping, you cannot configure bandwidth or priority in the same policy map. Sometimes the problem manifests itself when the peer-link is brought back up rather than taken down. Note This command does not require a license. Prerequisite of shared interfaces is that they are in trunk mode and spanning-tree allows it to come up quickly. It also provides information on how to obtain related documentation.
These are defined per the input and output queuing options of the specific module. Typically Nexus 5500 series switches are configured in pairs, so make sure to repeat the below configuration on the second switch. QoS The Nexus 7k comes with a default QoS policy of default-nq-8e-policy, which does not have a no drop CoS. To select ingress or egress, you specify either the input or output keyword in the service-policy command. This is the same syntax used on the Nexus 5x00 earlier in the chapter. Your software release might not support all the features in this document.
Example: fcoe config fcoe fka-adv-period 8 fcoe This example shows how to configure the advertisement interval for the fabric on a Cisco Nexus 7000 Series switch: switch switchto vdc fcoe type storage fcoe configure terminal fcoe config fcoe fka-adv-period 42. Related Commands Command Description class-map Creates or modifies a class map. Values can range from 1 to 126. Related Commands Command Description service-policy Attaches a policy map to an interface. Related Commands Command Description class-map Creates or modifies a class map.
The class map name can contain alphabetic, hyphen, or underscore characters, is case sensitive, and can be up to 40 characters. Some match criteria relate only to ingress or egress traffic. I have seen many examples where all commands are used, but why? The device does not support the no form of this command. Packet length Size range of Layer 3 packet lengths. Procedure Command or Action Purpose Step 1 switch configure terminal Enters global configuration mode. Optional Display the interface information for the virtual Fibre Channel interface.
Setting the System QoS Policy N7K-1 config Enter configuration commands, one per line. Here is just an overview of some things to do and consider. Does anyone have a tried and true QoS configuration for a Nexus 7k? In addition to thinking in terms of class-maps and policy-maps, there are some other key pieces that need to be understood. Step 5 Optional switch config copy running-config startup-config Optional Saves this configuration change. I'll post the resulting configs once we get things going. Failure to register may affect response times for initial service calls.
