What is 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 are the two modes you can set with LACP?
Link Aggregation Control Protocol (LACP) has two Channel modes and they are “Active” and “Passive”.
What are LACP modes?
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.
What is channel group mode desirable?
While “desirable” is a DTP negotiation mode, it is also a ether channel mode. There are two protocols for ether channel negotiation. PAgP is the Cisco proprietary protocol that employs desirable and auto, and LACP is the open standard that uses active and passive.
What are two channel group modes?
Answers Explanation & Hints: There are three modes available when configuring an interface for PAgP: on, desirable, and auto. Only desirable and auto place the interface in a negotiating state. The active and passive states are used to configure LACP and not PAgP.
What is the difference between LACP and PAgP?
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. Thus if you need to form the Etherchannel on stack switch, it is better to choose LACP instead of PAGP.
Can LACP be active active?
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. Passive mode—the interface is not in an active negotiating state.
What is port channel mode?
A port channel bundles individual interfaces into a group to provide increased bandwidth and redundancy. 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.
Should I use PAgP or LACP?
PAGP provides the same negotiation benefits as LACP. Both LACP and PAGP packets are exchanged between switches over Etherchannel capable ports….LACP vs PAGP: How They Differ From Each Other?
| Parameters | LACP | PAGP |
|---|---|---|
| Vendors Supported | Open Standard | Cisco Proprietary |
| Standard | Etherchannel and IEEE 802.3ad | Etherchannel |
Which two channel group modes would place an interface?
What’s the difference between active and passive voice?
Reviewing examples of active and passive voice will make it easier to understand the difference. Active voice describes a sentence where the subject performs the action stated by the verb. In passive sentences, the subject is acted upon by the verb.
What are the three modes of Port channeling?
When it comes to port-channeling there are three modes, “Active”, “Passive” and “on”. “on” is just being on, no negotiation. Hope that answers your question. 05-06-2012 01:41 PM 05-06-2012 01:41 PM Unfortunately, the above poster had some wrong information. While “desirable” is a DTP negotiation mode, it is also a ether channel mode.
What’s the difference between desirable and Auto Channel negotiation?
While “desirable” is a DTP negotiation mode, it is also a ether channel mode. There are two protocols for ether channel negotiation. PAgP is the Cisco proprietary protocol that employs desirable and auto, and LACP is the open standard that uses active and passive.
Which is better LACP mode passive or active?
LACP mode active is to be preferred as it allows to exchange LACP control frames on each member link and allows to prevent some issues that can arise from errors in cabling
