Why is LACP suspended?
LACP sets a port to the suspended state if it does not receive an LACP bridge protocol data unit (BPDU) from the peer ports in a port channel. This can cause some servers to fail to boot up as they require LACP to logically bring up the port. This command does not require a license.
Is down line protocol is down?
The line protocol being down indicates a clocking or framing problem. Probable reasons for this are encapsulation and clock rate mismatches. Ethernet0 is administratively down, line protocol is down: This output indicates that a local interface has been manually shut down using the shutdown command.
What is LACP suspend individual?
According to common sense “suspend-individual” means to me suspend any individual port within the port-channel that do not talk LACP with the peer.
What is the reason that the interface status is administratively down line protocol down?
What is the reason that the interface status is “administratively down, line protocol down”? A. There is no encapsulation type configured.
What are the two modes you can set with LACP?
LACP has two modes, i.e., Active mode (Ports initiate negotiation with other ports by exchanging LACP packets.) and Passive Mode (Ports reply to the received LACP packets but it doesn’t initiate LACP.).
How does Cisco LACP work?
LACP is defined in IEEE 802.3ad standard and enables Cisco switches to manage Ethernet channels between switches that conform to the standard. LACP facilitatesthe automaticcreation of EtherChannelsby exchanging LACP packets between Ethernet ports.
What is Down Down on Cisco?
So down down indicates a problem with the connection. And up down indicates that we believe that we have a valid connection but no ability to transmit and receive.
What is status up protocol down?
Basically, up/down means the port is available for a cable/connection, but doesn’t have one. Check the cable, or other computer.
How do I check my LACP?
You can display a detailed report or a summary of the LACP status by using the show command. You can view specific information about the load-balancing and frame-distribution schemes, specific information about the individual ports in the port channel, and general information about the port channel settings.
How do I configure LACP?
To configure LACP:
- Configure the interfaces for ae0.
- Configure ae0 interface for vlan tagging.
- Configure LACP for ae0 and configure periodic transmission of LACP packets.
- Configure ae0 as a trunk port.
- Configure the VLAN.
- Add the ae0 interface to the VLAN.
What happens if the LACP trunk is dropping BPDU’s?
mark9586 might have the correct answer. If the LACP trunk is dropping bpdu’s, then the trunk wouldn’t form at all. Does te1/1/2 come up if 1/1/1 is disconnected?
Is Lineline protocol down?
Line Protocol Is Down With HDLC HDLC is the default encapsulation type on a POS router interface. HDLC is an international standard, but vendor implementations vary one or more fields or the header or trailer in size and format.
Is a suspended port considered an individual link?
“A System may determine that a given link is not able to be aggregated with other links. Such links are referred to as Individual links (as opposed to Aggregateable links).” You then asked: “But from the line and protocol perspective, is a suspended port still in a “line up, protocol up” state?” Yes.
Why does my HDLC encapsulation interface undergoes repeated interface flaps?
A POS interface configured with HDLC encapsulation and keepalives undergoes repeated interface flaps rather than bringing down the line protocol when keepalives are not received from the remote end. This problem is resolved in Cisco bug ID CSCdp86387 ( registered customers only) .
