CISCO MDS CLI Cheat Sheet Show tech-support is one of the common command that we use in Cisco switches to collect almost all information about the switch. the session count of the link D. A logical port-channel interface will be created automatically. the number source-destination pairs on the link* What is. Also we really want to see the full configurations (there are other configurations that have an impact, for example, the STP priority that seems to make the new switch the root), and other things like the results from show vlan, show trunk, show port-channel, etc. Port-channel 1 with port members 1/0/23 and1/0/24 EC State is On Port State Displays as Port-channel Ag-inuse. To learn more, I recommend reading NX-OS and Cisco Nexus Switching by Ron Fuller, David Jansen, and Matthew McPherson. Cisco has a very useful command on the Nexus platform when it comes to checking the traffic load on the port channel members : show port-channel traffic interface port-channel x It's desirable to see balanced traffic over the port channel members specially when it comes to the FCoE traffic. Enter the show fex command to verify that all the FEXs are online. Configuring Link Aggregation (LAG) on a Cisco WLC 2504 and WLC Ports You can connect several different types of controller ports to your network: * Service port - Used for out-of-band management, system recovery, and initial boot functions; always connects to a switch port in access mode. A little research Geko is correct, right out of the BSMSN study guide Code: Select all To verify how effectively a configured load-balancing method is performing, you can use the show etherchannel port-channel command. EtherChannel is a Cisco term; General term is LAG (Link AGgregation) LAG goal is to trick STP into forwarding active/active; Supports 2, 4 or 8 interfaces; Split into 2 parts: Port Channel Interface Logical interface of bundled physical links; Member interfaces physical links that are part of the channel; Aggregates bandwidth of multiple links. show port-channel traffic by vlan - Cisco 6509 | LAN, Switching and Routing | Cisco Technical Support Forum | 6016 | 13309876 show port-channel traffic by vlan - Cisco 6509 | LAN, Switching and Routing | Cisco Support Community. Building a LACP port-channel between Cisco and Huawei switch January 16, 2018 January 23, 2018 Jerome Tissieres Configuring a LACP link aggregation, EtherChannel, or port-channel, or Eth-trunk between Huawei and Cisco switch is something very common. Cisco vPC aka Virtual Port-Channel, which was launched in 2009 is a feature on the Cisco Nexus series switches that allows end device to configure a Port-Channel across multiple switches. macro description CISCO_SMI_EVENT end Switch#show int g1/0/1 trunk Port Mode Encapsulation Status Native vlan Gi1/0/1 auto 802. show pagp Catalyst 2960-X Switch Layer 2 Command Reference, Cisco IOS Release 15. bond-slaves equates to the members of the bond. To perform this task, you, as always, rely on the show and debug commands. The Virtual Switch Link (VSL), like the VPC peer-link in VPC, is clearly a vital part of the VSS. 16 of the Cisco 300 Series Managed Switches Command Line Interface Guide Release 1. In the table, there is a load column. Cisco’s vPC is a virtual port-channel which allows links physically connected to two different switches to appear as a single device to a downstream device as part of a single port-channel. The Cisco Catalyst 6500 Series Virtual Switching System (VSS) allows the clustering of two chassis together into a single, logical entity. If you are new to the CNET Forums, please. etherchannel is the bundle itself of using for example 3 physical ports as 1 logical interface known as a port-channel. Note statistics are accumulative, and is reset by clearing corresponding interface. Please remember to be considerate of other members. I have to connect it to other port before it will come up. Speed shows the cumulative value of all the ISL link speeds. However, note the timing of the system messages:. The configuration applied to the port channel will also reflect on physical interfaces that are bundled into that port channel. show interfaces port-channel. Configure interface mlag-port-channel 100 no shutdown command at both Mellanox switches. The static and dynamic methods must use different group IDs and different port-channel members. I think more modern Cisco switches are more forgiving but I remember some real battles in the past with some of their older stuff. the existing etherchannel configuration was tougher to figure out and is what blew the thing this morning. NOTE: Port channels can contain a mix of Gigabit Ethernet and 10/100/1000 Ethernet interfaces, but Dell Networking OS disables the interfaces that are not the same speed of the first channel member in the port channel (refer to 10/100/1000 Mbps Interfaces in Port Channels ). first configure the physical interfaces with switchport mode trunk, then apply channel-protocol and last channel-group, the moment you will end with this configuration you will see logical interface of port-channel with blank only interface port-channel 1 will be written in show running-config, after going. This protocol makes sure that ports are eligible to the part of the same port channel and that they have an eligible partner switch. Certain show commands are supported by the Output Interpreter Tool (registered customers only) , which allows you to view an analysis of show command output. Protocol mismatch - decide between LACP or PAGP and make sure your port-channel is using the agreed protocol at both ends. R1#show int port-channel 1. Cisco Catalyst 3750 Series Switches The Cisco Catalyst 3750 Series switches are an innovative product line that improves LAN operating efficiency by combining industry-leading ease of use and the highest resiliency available for stackable switches. Steps to enable SNMP and SNMP Traps in Cisco Routers and Switches ManageEngine OpUtils is a comprehensive set of 30+ tools that helps network engineers monitor, diagnose and troubleshoot their IT resources. Enter the show vpc role command to verify the vPC switch role in a vPC topology. SWITCH(config)# trunk 5-7 Trk1 LACP. To make sure everything is functioning correctly, I can do a "show vpc" command to see the current status. ; if ports 1-10 are grouped for port-channel, 1-8 ports will be active and 9, 10 ports will be in suspended state. Cisco 3750 Stack with Port Channels how to view what are assigned? I have just taken over a Switch that is a 3750 stack with port channels.
