Create port-channel, Add port member

Page 88 highlights

Static Port-channels are statically configured. Dynamic Port-channels are dynamically configured using Link Aggregation Control Protocol (LACP). Member ports of a LAG are added and programmed into the hardware in a predictable order based on the port ID, instead of in the order in which the ports come up. Load balancing yields predictable results across resets and reloads. Create port-channel You can create up to 128 port-channels, with up to 32 port members per group. Configure a port-channel similarly to a physical interface - you can enable or configure protocols, or assign access control lists (ACLs) to a port channel. After you enable the port-channel, you can place it in L2 or L3 mode. To place the port-channel in L2 mode or configure an IP address to place the port-channel in L3 mode, use the switchport command. • Create a port-channel in CONFIGURATION mode. interface port-channel id-number Create port-channel OS10(config)# interface port-channel 10 Add port member When you add an interface to a port-channel: • The administrative status is applied to the port-channel. • The port-channel configuration is applied to the member interfaces. • A port-channel operates in either L2 (default) or L3 mode. To place a port-channel in L2 mode, use the switchport mode command. To place a port-channel in L3 mode and remove L2 configuration before you configure an IP address, use the no switchport command. • All interfaces should have the same speed. • An interface should not contain any non-default L2/L3 configuration settings - only the description and shutdown or no shutdowncommands are supported. You cannot add an IP address or a static MAC address to a member interface. • You cannot enable flow control on a port-channel interface - flow control is supported on physical interfaces that are port-channel members. • Port-channels support LACP (802.3ad). LACP identifies similarly configured links and dynamically groups ports into a logical channel. LACP activates the maximum number of compatible ports that the switch supports in a port-channel. If you globally disable spanning-tree operation, L2 interfaces that are LACP-enabled port-channel members may flap due to packet loops. Add port member - static LAG A static port-channel (LAG) contains member interfaces that you manually assign using the channel-group mode on command.

Static
Port-channels are statically
configured.
Dynamic
Port-channels are dynamically
configured
using Link Aggregation Control Protocol (LACP).
Member ports of a LAG are added and programmed into the hardware in a predictable order based on the port ID, instead of in the order in
which the ports come up. Load balancing yields predictable results across resets and reloads.
Create port-channel
You can create up to 128 port-channels, with up to 32 port members per group.
Configure
a port-channel similarly to a physical interface —
you can enable or
configure
protocols, or assign access control lists (ACLs) to a port channel. After you enable the port-channel, you can
place it in L2 or L3 mode.
To place the port-channel in L2 mode or
configure
an IP address to place the port-channel in L3 mode, use the
switchport
command.
Create a port-channel in CONFIGURATION mode.

Add port member
When you add an interface to a port-channel:
The administrative status is applied to the port-channel.
The port-channel
configuration
is applied to the member interfaces.
A port-channel operates in either L2 (default) or L3 mode. To place a port-channel in L2 mode, use the
switchport mode
command. To place a port-channel in L3 mode and remove L2
configuration
before you
configure
an IP address, use the
no
switchport
command.
All interfaces should have the same speed.
An interface should not contain any non-default L2/L3
configuration
settings — only the
description
and
shutdown
or
no
shutdown
commands are supported. You cannot add an IP address or a static MAC address to a member interface.
You cannot enable
flow
control on a port-channel interface —
flow
control is supported on physical interfaces that are port-channel
members.
Port-channels support LACP (802.3ad). LACP
identifies
similarly
configured
links and dynamically groups ports into a logical channel.
LACP activates the maximum number of compatible ports that the switch supports in a port-channel.
If you globally disable spanning-tree operation, L2 interfaces that are LACP-enabled port-channel members may
flap
due to packet
loops.
Add port member — static LAG
A static port-channel (LAG) contains member interfaces that you manually assign using the
channel-group mode on
