How do I configure EtherChannel?
Perform these steps to configure the EtherChannel feature on Cisco 1900, 2900 and 3900 series ISRs. Enters global configuration mode. Specify the EtherChannel (port channel) logical interface, and enter interface configuration mode. Assign an IP address and subnet mask to the EtherChannel.
Is EtherChannel the same as LACP?
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.
What are two requirements to be able to configure an EtherChannel?
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 Channel protocol LACP?
The Link Aggregation Control Protocol (LACP), described by IEEE 802.3ad, defines a method for two switches to automatically establish and maintain link aggregation groups (LAGs, also called channel groups or port channels). Using LACP, a switch can configure LACP-compatible ports into a dynamic LAG.
How do I check my port channel settings?
Use the command, show port-channel summary, to verify the number of port-channels already configured. You can have a maximum of 256 port channels on the Cisco Nexus 1000V. Use this procedure to force the physical interface to take on the characteristics of the port channel.
When EtherChannel is configured which mode will force?
When EtherChannel is configured, which mode will force an interface into a port channel without exchanging aggregation protocol packets? The remaining two interfaces continue to load balance traffic. A network administrator configured an EtherChannel link with three interfaces between two switches.
How many etherchannels can I add to a catalyst 2960-s?
For a mixed stack containing one or more Catalyst 2960-S switches, we recommend that you configure no more than six EtherChannels on the stack. With PAgP, if the active switch fails or leaves the stack, the standby switch becomes the new active switch.
Do I need an account on Cisco to set up EtherChannel?
An account on Cisco.com is not required. All ports in an EtherChannel must be assigned to the same VLAN or they must be configured as trunk ports. When the ports in an EtherChannel are configured as trunk ports, all the ports must be configured with the same mode (either Inter-Switch Link [ISL] or IEEE 802.1Q).
How do I configure layer 2 etherchannels?
You configure Layer 2 EtherChannels by assigning ports to a channel group with the channel-group interface configuration command. This command automatically creates the port-channel logical interface.
What is the basic configuration of the Cisco router?
Basic configuration of the Cisco router. Access to the Internet. Let’s consider the simplest case when you have to hook up 3 departments of a company to different logical networks ( Vlans) using one access layer switch Cisco 2960 (Sometimes they are called switches of the second layer of OSI model).
