What does it mean when a port is suspended?
What does it mean when a port is suspended?
When a port in the etherchannel is in a suspended state means the port configuration is not compatible with others in the same etherchannel.
How do I configure port channels on my Nexus?
Cisco Nexus 9k Port Channel Configuration – Step by Step
- Erase the previous configuration on switches NXOS01, NXOS02, NXOS03 and NXOS04 using command “write erase” and reload both switches, assign hostname the same hostname to both switches.
- Configure port channels between NXOS01, NXOS02, NXOS03, and NXOS04 as follows:
How do I check my port channel mode?
You are logged in to the CLI in configuration mode. Issue the show port-profile name profile-name command to verify that you have configured a port channel in the profile. Issue the debug port-channel trace command. VLAN traffic does not traverse trunk.
What is Lacp in Nexus?
About Port Channels For more flexibility, you can use the Link Aggregation Control Protocol (LACP), which is defined in IEEE 802.3ad. When you use LACP, the link passes protocol packets. You cannot configure LACP on shared interfaces.
What layer is Lacp?
Layer 2
Starting in Junos OS Release 15.1X49-D80, Link Aggregation Control Protocol (LACP) is supported in Layer 2 transparent mode in addition to existing support in Layer 3 mode for SRX300, SRX320, SRX340, SRX345, SRX1500, SRX4100, SRX4200 devices and vSRX instances.
What is the difference between PAGP and Lacp?
Both LACP and PAGP packets are exchanged between switches over Etherchannel capable ports. The most significant difference is the vendors supported for them. LACP is open standard and supported by most of vendors, while PAGP is Cisco proprietary only used between Cisco devices.
Why do we need port channel?
A port channel is an aggregation of multiple physical interfaces that creates a logical interface. You can bundle up to eight individual active links into a port channel to provide increased bandwidth and redundancy. Port channeling also load balances traffic across these physical interfaces.
Is LACP Layer 2?
Starting in Junos OS Release 15.1X49-D40 and Junos OS Release 17.3R1, Link Aggregation Control Protocol (LACP) is supported in Layer 2 transparent mode in addition to existing support in Layer 3 mode for SRX5400, SRX5600 and SRX5800 devices. LACP is compatible with other peers that run the 802.3ad LACP protocol.
Should I use PAGP or LACP?
Both LACP and PAGP protocols are used for link aggregation. Besides, LACP can support cross-stack, while PAGP does not since it does not support participating interfaces on different physical switches. Thus if you need to form the Etherchannel on stack switch, it is better to choose LACP instead of PAGP.
Why is the FEX port inactive on my Nexus?
In dealing with the Nexus platforms, I’ve seen the “inactive” status show up in four different situations: The VLAN the port was assigned to does not exist on the switch. The port is part of a virtual port-channel (vPC) on a dual-homed FEX, and the FEX port configurations do not match on the two Nexus switches in the vPC domain.
Why is Cisco Nexus port 116 being suspended?
2013 Apr 18 23:59:59 NEXUS-SWITCH-2 %ETHPORT-3-IF_ERROR_VLANS_SUSPENDED: VLANs 116 on Interface Ethernet116/1/11 are being suspended. (Reason: Vlan is not configured on remote vPC interface) Note that you could set your syslog parsing engine to trigger an alert based on the message above.

How does port channeling work in Cisco Nexus 9000?
Port channeling also load balances traffic across these physical interfaces. The port channel stays operational as long as at least one physical interface within the port channel is operational.
