Configure portchannel on Cisco 9500
Portchannel is Cisco’s implementation of the EtherChannel
technology, (usually) based on the 802.3ad standard
).
Step-by-step guide
Portchannel configuration
To configure portchannel
on Cisco 9500, first create a portchannel
interface:
!
interface Port-channel1
description *** Port-Channel to XYZ***
switchport
switchport mode trunk
switchport nonegotiate
logging event bundle-status
!
After that configure an interface and match the channel-group
with the portchannel ID
.
!
interface TwentyFiveGigE1/0/5
description *** Port-Channel to XYZ***
switchport
switchport mode trunk
switchport nonegotiate
logging event link-status
logging event trunk-status
logging event bundle-status
udld port aggressive
channel-protocol lacp
channel-group 1 mode active
service-policy input AutoQos-4.0-Trust-Cos-Input-Policy
service-policy output AutoQos-4.0-Output-Policy
!
Please note that all the ports on the C9500 series are configured as
routed ports
by default, so we need to manually configure them asswitchport
if we want to use them asL2 interfaces
.
Some of the parameters used in this example are optional (such as description
, service-policy
and logging event
parameters), while others are mandatory.
At minimum, you should configure switchport
parameter, what channel-protocol
you will be using and what channel-group
the port belongs to.
