What is virtual port channel in Nexus?

What is virtual port channel in Nexus?

vPC (Virtual Port-Channel), also known as multichassis EtherChannel (MEC) is a feature on the Cisco Nexus switches that provides the ability to configure a Port-Channel across multiple switches (i.e. vPC peers). vPC is similar to Virtual Switch System (VSS) on the Catalyst 6500s.

What is port channel in switch?

A port channel is a communication link between two switches supported by matching channel group interfaces on each switch. A port channel is also referred to as a Link Aggregation Group (LAG). Port channels combine the bandwidth of multiple Ethernet ports into a single logical link.

What are orphan ports in Nexus?

Orphan Port – Any port not configured as a vPC, but which carries a vPC VLAN.

What are Virtual Port Channels?

vPC’s, or Virtual Port Channels, are a Cisco Nexus technology. They are used to connect layer-2 devices to two switches at once. This makes it possible to create a highly available environment in the data centre. If one switch fails, the other one continues to operate.

How many VDC can be configured in Nexus?

The maximum number of VDCs that can be configured per Nexus 7000 chassis is four; the default VDC (VDC 1) and three additional VDC(s).

How do I add a VLAN to a port channel?

Procedure

1. Log in to the primary Cisco Nexus series switch.
2. To run the configuration, type: Switch-A# config terminal.
3. To specify the port channel, type: Switch-A(config)# interface port-channel
4. To add the VLANs, type: Switch-A(config)# switchport trunk allowed vlan add VLAN_IDs.

Does port channel increase speed?

A port channel does a couple of things: Increases the available bandwidth between two devices. Creates one logical path out of multiple physical paths. Since Spanning Tree Protocol (STP) runs on the logical link and not the physical links, all of the physical links can be in a forwarding state.

How do I configure a port channel on a switch?

The basic process for configuring your EtherChannel interfaces is as follows:

1. Connect to the command-line interface (CLI) your switch.
2. Access Privileged EXEC mode.
3. Access Global Configuration mode.
4. Access Interface Configuration mode.
5. Change switchport to trunk or access, but all ports must be in the same VLAN.

What is the difference between VSS and vPC?

3) VSS can support L3 port-channels across multiple chassis,however, vpc is used for L2 port-channels only. 5) VSS mainly used for campus environment whereas VPC is used for Data Center environment. 6) In VSS, only one logical switch has be managed from management and configuration point of view.
