How do I configure port channels on my Nexus?
Create Port Channel The Nexus 3550-T enables users to create port-channels by using the CLI. The above command creates a port-channel with id 1. This port-channel will be using the source and destination mac addresses for distributing the traffic across the member interfaces of the port-channel.
How do I set span on Nexus?
Note: USM Anywhere supports SPAN, RSPAN, ERSPAN, and VMware Encapsulated Remote Mirroring (L3) Source, which is an ERSPAN-like feature. Open a monitor session. Enter global configuration mode. Enter interface configuration mode for the specified Ethernet interface selected by the port values.
Does Nexus 9K support Netflow?
Nexus 9k (Nexus 9000) Netflow support. This program connects you with professional consulting resources who are experienced with the Orion Platform and its products.
Does Nexus support PAgP?
Cisco NX-OS does not support Port Aggregation Protocol (PAgP) for EtherChannels. An EtherChannel bundles individual links into a channel group to create a single logical link that provides the aggregate bandwidth of up to 16 physical links.
How do I check my port channel settings?
Use the command, show port-channel summary, to verify the number of port-channels already configured. You can have a maximum of 256 port channels on the Cisco Nexus 1000V. Use this procedure to force the physical interface to take on the characteristics of the port channel.
How do I create a port channel?
You create a port channel by bundling compatible interfaces. You can configure and run either static port channels or port channels running the Link Aggregation Control Protocol (LACP). Any configuration changes that you apply to the port channel are applied to each member interface of that port channel.
What is Rspan Cisco?
RSPAN allows you to monitor traffic from source ports distributed over multiple switches, which means that you can centralize your network capture devices. RSPAN works by mirroring the traffic from the source ports of an RSPAN session onto a VLAN that is dedicated for the RSPAN session.
What is sFlow vs NetFlow?
SFlow is a pure packet sampling technology. The most notable difference of SFlow vs NetFlow is that SFlow is network layer independent and has the ability to sample everything and to access traffic from OSI layer 2-7, while NetFlow is restricted to IP traffic only.
What is sFlow Cisco?
Sampled flow (sFlow) allows you to monitor real-time traffic in data networks containing switches and routers. It uses the sampling mechanism in the sFlow agent software on switches to monitor traffic and to forward the sample data to the central data collector. The core sFlow agent workflow goes as follows: 1.
What are two advantages of LACP?
Using Link Aggregation Control Protocol (LACP) increases bandwidth in 1 direction. The device employing LACP can link more than 1 physical interface together. Using Link Aggregation Control Protocol (LACP) increases bandwidth in 1 direction. The device employing LACP can link more than 1 physical interface together.
What is channel group mode active?
Channel-group mode active means that LACP will be enabled on the LAG. You would have trouble with this if the other side is not configured for LACP as well. You do not need to use LACP in order for the LAG to work with VLAG or any other protocol really.
How do I check my Nexus port channel?
How is RSPAN traffic transferred from Nexus 1 to Nexus 2?
From the Nexus 1 switch, the SPAN traffic from the source is carried to the destination port and copied onto the RSPAN VLAN. The traffic is then forwarded over the link to the Nexus 2 switch on the Ethernet 1/1 interface.
Can I use RSPAN with the Nexus 7000 switch?
The Nexus 7000 Series Switch is limited in what it can do with RSPAN. An RSPAN VLAN cannot be used as a SPAN destination. Therefore, the Nexus 7000 switch can only use RSPAN as a transit VLAN or a source VLAN and pull data from the RSPAN VLAN. You cannot place anything into the RSPAN VLAN from the Nexus 7000 switch.
What is encapsulated remote span (erspan)?
Encapsulated remote SPAN (ERSPAN) brings generic routing encapsulation (GRE) for all captured traffic and allows it to be extended across Layer 3 domains. ERSPAN is a Cisco proprietary feature and is available only to Catalyst 6500, 7600, Nexus, and ASR 1000 platforms to date.
Does n9k support RSPAN?
05-16-2017 02:58 AM 05-16-2017 02:58 AM I have read that N9K doesn’t support RSPAN but I see at my boxes that the vlan 666 is a remote span. What is more interesting that is working fine however I don’t know how vlan 666 was defined. I ask because nowadays I couldn’t create next remote vlan ie. Vlan 669 as a remote span.
