How do I enable LACP on Cisco Nexus?
Configuring the LACP Port Priority
- switch# configure terminal. Enters configuration mode.
- switch(config)# interface type slot/port. Specifies the interface to configure, and enters the interface configuration mode.
- switch(config-if)# lacp port-priority priority. Configures the port priority for use with LACP.
What is LACP in Nexus?
Link Aggregation Control Protocol IEEE 802.3ad (LACP) is an open standard of Ethernet link aggregation. LACP allows Cisco switches to manage Ethernet channels between switches that conform the 802.3ad protocol. There are few LACP modes: “active”, “passive” and “on”.
How do I add a port to a port channel?
The basic process for configuring your EtherChannel interfaces is as follows:
- Connect to the command-line interface (CLI) your switch.
- Access Privileged EXEC mode.
- Access Global Configuration mode.
- Access Interface Configuration mode.
- Change switchport to trunk or access, but all ports must be in the same VLAN.
Can a port channel be a trunk?
Port channels enable several physical links to be combined into one aggregated logical link. Trunking enables a link to carry (trunk) multiple VLAN traffic. Use the show port-channel compatibility-parameters CLI command to determine port channel requirements.
Can a layer 3 configuration be applied to a port channel?
You cannon apply Layer 3 configurations to an individual port-channel member either; you must apply the configuration to the entire port channel. You can create subinterfaces on a Layer 3 port channel, even though a subinterface is part of the logical port-channel interface.
How are port channels created in Cisco Nexus 9000?
You can create port channels directly by creating the port-channel interface, or you can create a channel group that acts to aggregate individual ports into a bundle. When you associate an interface with a channel group, the software creates a matching port channel automatically if the port channel does not already exist.
Can a layer 2 interface function as a trunk port?
A Layer 2 interface can function as either an access port or a trunk port; it cannot function as both port types simultaneously. When you change a Layer 2 interface back to a Layer 3 interface, that interface loses all the Layer 2 configuration and resumes the default VLAN configurations.
What kind of ports does a Cisco Nexus 9300 have?
A trunk port can have two or more VLANs configured on that port; it can carry traffic for several VLANs simultaneously. By default, all the ports on Cisco Nexus 9300-EX switches are Layer 3 ports and all the ports on Cisco Nexus 9300 switches are Layer 2 ports.
