What are two requirements to be able to configure an EtherChannel between two switches choose two?
What are two requirements to be able to configure an EtherChannel between two switches? (Choose two.)
- The interfaces that are involved need to be contiguous on the switch.
- All the interfaces need to work at the same speed.
- All the interfaces need to be working in the same duplex mode.
What is the difference between LACP and EtherChannel?
EtherChannel supports both LACP and Cisco’s PAgP, whereas 802.3ad uses LACP. LACP allows for up to 8 active and 8 standby links, whereas PAgP only allows for 8 active links.
Which two EtherChannel modes can create an LACP EtherChannel?
A port in the desirable mode can form an EtherChannel with another port that is in the desirable or auto mode. A port in the auto mode can form an EtherChannel with another port in the desirable mode….PAgP Mode negotiation –
| PAgP Mode | Desirable | Auto |
|---|---|---|
| Desirable | Yes | Yes |
| Auto | Yes | No |
What kind of EtherChannel auto negotiation is done if the two modes on either side are desirable and desirable?
Desirable mode: Desirable mode in Port Aggregation Protocol (PAgP) initiates the negotiation and tries to form EtherChannel with other end….Port Aggregation Protocol (PAgP) Modes.
| Desirable | Auto | |
|---|---|---|
| Auto | Yes | No |
Which two parameters must match on the ports of two switches to create a PAgP EtherChannel between the switches?
For an EtherChannel to be created, the ports that are concerned on the two switches must match in terms of the speed, duplex, and VLAN information.
What is a requirement to configure a trunking EtherChannel between two switches?
What is a requirement to configure a trunking EtherChannel between two switches? The participating interfaces must be physically contiguous on a switch. The allowed range of VLANs must be the same on both switches. The participating interfaces must be on the same module on a switch.
What is Layer 2 EtherChannel?
A layer2 etherchannel is seen as a single link by STP allowing to use all the member links for better performance. Most of the times a layer2 etherchannel is configured as a trunk ( 802.1Q more often) and can carry multiple Vlans/broadcast domains.
What are two advantages of EtherChannel choose two?
What are two advantages of EtherChannel? (Choose two.)
- Configuring the EtherChannel interface provides consistency in the configuration of the physical links.
- Load balancing occurs between links configured as different EtherChannels.
- EtherChannel uses upgraded physical links to provide increased bandwidth.
Which mode must be used to configure EtherChannel between two switches without using a negotiation protocol?
Which mode must be used to configure EtherChannel between two switches without using a negotiation protocol? The Static Persistence (or ג€onג€ mode) bundles the links unconditionally and no negotiation protocol is used. In this mode, neither PAgP nor LACP packets are sent or received.
Which three parameters must match on the ports of two switches for a PAgP EtherChannel to be created?
Explanation: For an EtherChannel to be created, the ports that are concerned on the two switches must match in terms of the speed, duplex, and VLAN information.
Which two mode combinations would result in the successful negotiation of an EtherChannel choose two *?
Which two mode combinations would result in the successful negotiation of an EtherChannel? (Choose two.) Explanation: The combinations of modes that will form an EtherChannel are as follows: on/on, active/passive, active/active, desirable/auto, and desirable/desirable. 12.
Which combinations of PAgP modes will form an EtherChannel choose all that apply?
Explanation: The combinations of modes that will form an EtherChannel are as follows: on/on, active/passive, active/active, desirable/auto, and desirable/desirable.
