What is channel group mode active?
Re: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.
What is active mode in LACP?
Active mode—the interface is in an active negotiating state. LACP runs on any link that is configured to be in the active state. The port in an active mode also automatically initiates negotiations with other ports by initiating LACP packets.
What is channel group mode desirable?
on means force channelling on, but do not negotiate with the other side. desirable means try and negotiate with the other side, and if he agrees, then enable the channel.
What is the difference between LACP and PAgP?
LACP is an Open standard, i.e., supported by most vendors. While PAGP is Cisco proprietary; i.e., PAGP can only be used between Cisco devices. LACP has two modes, i.e., Active mode (Ports initiate negotiation with other ports by exchanging LACP packets.)
Should I use PAgP or LACP?
LACP is open standard and supported by most of vendors, while PAGP is Cisco proprietary only used between Cisco devices. Besides, LACP can support cross-stack, while PAGP does not since it does not support participating interfaces on different physical switches.
What are two channel group modes?
Which two channel group modes would place an interface in a negotiating state using PAgP? (Choose two.)
- on.
- desirable.
- active.
- auto.
- passive. Answers Explanation & Hints: There are three modes available when configuring an interface for PAgP: on, desirable, and auto.
What is the range for Channel-group-number and mode?
For channel-group-number, the range is 1 to 26. This number must be the same as the port-channel-number (logical port) configured in the “Creating Port-Channel Logical Interfaces” section . For mode, select one of these keywords:
What is the difference between Channel-Group 1 mode on/desirable?
Re: Channel-group 1 mode on / desirable. on means force channelling on, but do not negotiate with the other side. desirable means try and negotiate with the other side, and if he agrees, then enable the channel. If you have on on one side and desirable on the other, then it will not form a channel because no negotiation will take place.
How do I assign a port to a channel group?
Assign the port to a channel group, and specify the PAgP or the LACP mode. For channel-group-number, the range is 1 to 26. This number must be the same as the port-channel-number (logical port) configured in the “Creating Port-Channel Logical Interfaces” section .
How do I enable PAgP or LACP mode in a channel group?
channel-group channel-group-number mode {auto [non-silent] | desirable [non-silent] | on} | {active | passive} Assign the port to a channel group, and specify the PAgP or the LACP mode. For channel-group-number, the range is 1 to 26. For mode, select one of these keywords: • auto— Enables PAgP only if a PAgP device is detected.
