It
allows directly connected switches to negotiate an EtherChannel link
. It provides a simulated environment for testing link aggregation. It decreases the amount of configuration that is needed on a switch.
What are two advantages of using LACP choose two it decreases the amount of configuration that is needed on a switch?
It decreases the amount of configuration that is needed on a switch. It
provides a simulated environment for testing link aggregation
. It allows the use of multivendor devices. LACP allows Fast Ethernet and Gigabit Ethernet interfaces to be mixed within a single EtherChannel.
What are the advantages of LACP?
LACP
allows Fast Ethernet and Gigabit Ethernet interfaces to be mixed within a single EtherChannel
. It eliminates the need for configuring trunk interfaces when deploying VLANs on multiple switches. It allows directly connected switches to negotiate an EtherChannel link.
What is the difference between LACP and PAGP?
Both LACP and PAGP packets are exchanged between switches over Etherchannel capable ports. 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.
What is LACP port priority?
The LACP Port-priority
determines the ports that are placed in standby mode when hardware limitations prevent a single aggregation of all compatible ports
.
Does LACP load balance?
Load Balancing in LACP Mode
To prevent out-of-order packets, Eth-Trunk
uses flow-based load balancing
. This mechanism uses the hash algorithm to calculate the address in a data frame and generate a hash key based on which the system searches for the outbound interface in the Eth-Trunk forwarding table.
What is the difference between LACP active and passive?
Active mode—the interface is in an active negotiating state. LACP runs on any link that is configured to be in the active state. …
Ports in passive mode respond to LACP packets
. A port in a passive mode cannot set up a port channel (LAG group) with another port in a passive mode.
Does LACP increase bandwidth?
Will configuring LACP increase throughput on the link? A: LACP/Port channel allows multiple ports to be bundled between the controller and the uplink switch. … However, the maximum throughput between any two devices behind each end of the port
channel will not exceed the link speed
of the physical port in the path.
What is an advantage of Pvst +?
PVST+ is
an enhancement for Common STP
which separates 802.1d spanning-tree instance for each VLAN. This protocol is more efficient on the links, however it causes higher CPU and memory usage.
Which two issues are the result of a broadcast storm choose two?
Which two issues are the result of a broadcast storm? Due to high processing demands during a broadcast storm ,
communication may fail between end stations in the broadcast domain
. Durining a boardcast storm , constant changes to the MAC address table prevent a switch from accurately forwarding frames.
How does LACP negotiate?
The LACP provides a standard negotiation mechanism for
a switching device
so that the switching device can automatically form and start the aggregated link according to its configuration. After the aggregated link is formed, LACP is responsible for maintaining the link status.
What does LACP stand for?
Link Aggregation Control Protocol
(LACP) (802.3ad) for Gigabit Interfaces – Cisco.
What is the difference between LACP and EtherChannel?
EtherChannel vs.
Both technologies are capable of automatically configuring this logical link.
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 is LACP rate?
LACP Rate.
Specifies how fast the bonded interfaces should transmit LACPDU packets
. The default is every 30 seconds, characterized by the lacp_rate value of “0” or “slow”, or every second, characterized by the lacp_rate value of “1” or “fast”.
What is a port channel used for?
Port channels
aggregate multiple physical interfaces into one logical interface to provide higher bandwidth, load balancing, and link redundancy
. channel. Load balances across multiple links and maintains optimum bandwidth usage.
How does Cisco LACP work?
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. You can configure maximum 16 ports to form a channel depending on IOS version and platform.
