Mod 6.2-6.3: Configure EtherChannel Flashcards
CONFIG GUIDELINES:
All Ethernet interfaces must support EtherChannel with no requirement that interfaces be physically contiguous
EtherChannel support
CONFIG GUIDE:
Configure all interfaces in an EtherChannel to operate at the same speed and in the same duplex mode.
Speed and duplex
CONFIG GUIDE:
All interfaces in the EtherChannel bundle must be assigned to the same VLAN or be configured as a trunk (shown in the figure).
VLAN match
CONFIG GUIDE:
An EtherChannel supports the same allowed range of VLANs on all the interfaces in a trunking EtherChannel. If the allowed range of VLANs is not the same, the interfaces do not form an EtherChannel, even when they are set to auto or desirable mode.
Range of VLANs
LACP Config:
Step 1: Use __ command to specify the interfaces that compose the EtherChannel group
interface range interface
LACP Config:
Step 2: Use the ___ to create the port channel interface and to identify the LACP EtherChannel Config
channel-group identifier mode active
L-ACP Config:
Step 3: Use the ___ to change Layer 2 settings on the port channel interface.
interface port-channel
VERIFY ETHERCHANNEL:
The __ command displays the general status of the port channel interface
show interfaces port-channel 1
VERIFY ETHERCHANNEL:
The ___ is used to display one line of info per channel
show etherchannel summary
VERIFY ETHERCHANNEL:
The ___ command display info about a specific port channel interface
show etherchannel port -channel
VERIFY ETHERCHANNEL:
The _____ command can provide info abt the role of the interface in the EtherChannel
show interfaces etherchannel
COMMON ETHERCHANNEL CONFIG ISSUE:
Choose the correct answer:
A. All interfaces within EtherChannel can have varying config of speed and duplex mode, native and allowed VLANs on trunks, and access VLAN on access ports
B. All interfaces within an EtherChannel must have the same configuration of speed and duplex mode, native and allowed VLANs on trunks, and access VLAN on access ports
B
COMMON ETHERCHANNEL CONFIG ISSUE:
Assigned ports in the EtherChannel are ____ the same VLAN, or not configured as trunks
not part of
COMMON ETHERCHANNEL CONFIG ISSUE:
True or false.
Ports with different native VLANs cannot form an EtherChannel.
True
COMMON ETHERCHANNEL CONFIG ISSUE:
True or false.
In an EtherChannel, we can configure one port as trunk and the other as others.
False.
It is not recommended that you configure trunking mode on individual ports that make up the EtherChannel. When configuring a trunk on an EtherChannel, verify the trunking mode on the EtherChannel.
